Having trouble solving logic of random number game

I am relatively new to java programming. I am currently working on building a mini guessing game, as a project to learn more Java. I am having some issues with the following:
Here are the 4 main things I am having trouble solving.
Record the answer for each user, if incorrect.
If the user was correct, skip them in subsequent rounds.
Once all players have guessed their correct number, print out the number of guesses it took for each one to guess correctly, the incorrect responses, and show a ranking of the players.
Ask if the user(s) wish to play again. If so, reset all values.
Here are the methods that I have written;
import java.io.*;
public class MultiPlayerRandomGame {
// this method asks how many users will be playing and returns the number of users
public static int howManyUsers() {
System.out.println("How many users will be playing?");
int players = IO.readInt();
return players;
}
// this method generates and returns a random number
public static int generateRandomNumber() {
int randomNumber = (int) (Math.random() * 100);
return randomNumber;
}
// this method compares user's entered guess and the generated random number then returns true/false
public static boolean compareGuess(int guess, int randomNumbers) {
boolean isGuessCorrect = false;
if (guess == randomNumbers) {
System.out.println("CORRECT!");
isGuessCorrect = true;
} else if (guess > randomNumbers) {
System.out.println("Too High");
} else if (guess < randomNumbers) {
System.out.println("Too Low");
}
System.out.println("test1");
return isGuessCorrect;
}
// this method determines whether Player N is correct or incorrect
public static boolean nextPlayer(int numOfUsers, int[] numberOfGuesses, int[] randomNumbers, int[][] numberBoard) {
for (int n = 0; n < numOfUsers; n++) {
int guessedNumber = numberOfGuesses[n];
/* if (guessedNumber == 0) {
return false;
}*/
if (numberBoard[n][guessedNumber] != randomNumbers[n]) {
return false;
}
}
return true;
}
/* this method is supposed to print out the number of guesses it took each player to guess their correct number
* CORRECTION: change the logic of this method to printing the number of guesses for one player then
* in the main method or wherever, make a for loop that prints out the number of guesses for each player
*/
public static void amountOfGuesses(int numOfUsers, int [] numberOfGuesses, int [][] numberBoard) {
int n = 0;
for ( int i = 0; i < numOfUsers; i++ ) {
n = n + 1;
System.out.println("Player " + n + " guessed " + numberOfGuesses[i]+ " time(s)");
}
}
// this method determines whether the user(s) would like to play again
public static boolean playAgain(String answer) {
boolean userWillPlayAgain;
if (answer.compareToIgnoreCase("no") == 0) {
userWillPlayAgain = false;
}
else {
userWillPlayAgain = true;
}
return userWillPlayAgain;
}
// this method controls the entire game
public static boolean playGame(){
boolean gameTerminate = false;
int numOfUsers = howManyUsers();
int [] randomNumbers = new int[numOfUsers];
int [] numberOfGuesses = new int [numOfUsers];
int [][] numberBoard = new int [numOfUsers][100];
// this for loop assigns the n random number(s) to the n player(s)
for (int n = 0; n < numOfUsers; n++){
randomNumbers[n] = generateRandomNumber();
System.out.println("PLAYER " + (n+1) + "'s RANDOM NUMBER: " + randomNumbers[n]);
}
do {
for (int i = 0; i < numOfUsers; i++) {
int guessedNumber = numberOfGuesses[i];
if (guessedNumber == 0 || numberBoard[i][guessedNumber-1] != randomNumbers[i]) {
System.out.println("Enter your guess Player " + (i+1) + ":");
int enteredGuess = IO.readInt();
numberBoard[i][guessedNumber] = enteredGuess;
numberOfGuesses[i] = guessedNumber + 1;
if(compareGuess(enteredGuess, randomNumbers[i])){
return true;
}
}
}
/* int n = 0;
* for ( int j = 0; j < numOfUsers; j++ ) {
n = n + 1;
System.out.println("Player " + n + " guessed " + numberOfGuesses[j]+ " time(s)"); }
*/
} while (nextPlayer(numOfUsers, numberOfGuesses, randomNumbers, numberBoard) == false);
// System.out.println("test");
return gameTerminate;
}
public static void main(String[] args){
boolean playing = true;
while (playing) {
playGame();
System.out.println("Would you like to play again?");
String answer = IO.readString();
playing = playAgain(answer);
}
System.out.println("OK, goodbye!");
}
}
Main issue as of right now: The game terminates and asks if user would like to play again after a player guesses their number, rather than after every player guesses their number.
Do I need actual Objects to make this happen and track every player or can this still be solved without objects? This is a territory I am unfamiliar with.

Right now your playGame method returns true back to main whenever any guess returns correct from compareGuess.
I would recommend setting up another array boolean[] correctGuess in playGame and mark the player number index as true if a player guesses correctly. You can use this new array to skip players who have guessed correctly, also. Once all players are marked true you can return to main.

This won't help improve your current code, but the same game can easily implemented using objects. In my opinion, the code is cleaner and easier to read.
Objects allow you to encapsulate the data required by each class. The target, number of guesses, and whether they were correct is stored in the Person object instead of in a multi-dimensional array. The values can be accessed by referencing the Person object - e.g. person.numGuesses or person.target.
By using objects, you can keep specific functionality scoped out of the main class. i.e. abstract away the implementation. In a future version of the game, you may want to change the way the target value is incremented; by using objects, the change can be made in the class which sets and checks the value - without affecting any other classes.
import java.util.ArrayList;
import java.util.List;
import java.util.Random;
import java.util.Scanner;
public class Game {
private final List<Person> personList = new ArrayList<>();
private Game(int numPlayers) {
for (int i = 0; i < numPlayers; i++) {
personList.add(new Person(i)); // Fill the player list
}
}
public static void main(String[] args) {
System.out.print("Enter the number of players: ");
Scanner sc = new Scanner(System.in);
int numPlayers = sc.nextInt();
// Initialise with the number of players
Game g = new Game(numPlayers);
g.mainLoop(); // Play the game
boolean playAgain = false;
do {
System.out.print("Do you wish to play again?: ");
String in = sc.next();
playAgain = "yes".equals(in);
if (playAgain) {
g.resetAll();
g.mainLoop();
}
} while (playAgain); // Only loop if they answered "yes"
}
private boolean allCorrect() {
// Check if all players have answered correctly
return personList.stream().allMatch(p -> p.correct);
}
private void resetAll() {
for (Person p : personList) {
p.reset(); // Reset each person
}
}
private void mainLoop() {
while (!allCorrect()) {
for (Person p : personList) {
p.doGuess(); // Ask for the guess
}
}
// Everyone is correct, print the scores.
for (Person p : personList) {
System.out.println("Player " + p.id + " => " + p.numGuesses + " guesses");
}
}
}
class Person {
final int id;
int numGuesses;
boolean correct;
private int target;
Person(int id) {
this.id = id;
target = new Random().nextInt(100); // Each player has a random target between 0-100
}
void doGuess() {
if (correct) {
// Skip turn if they're already correct
return;
}
numGuesses++;
System.out.print("Player " + id + " guess " + numGuesses + "(" + target + "): ");
Scanner sc = new Scanner(System.in);
int i = sc.nextInt(); // Read the guess
if (i == target) {
correct = true;
System.out.println("Correct!");
}
}
void reset() {

numGuesses = 0; // Reset the counter
correct = false;
}
}

Java classes and calling variables in other classes

I'm still fairly new in java programming and I've gotten some aspects down but the classes within Java are by far giving me the most trouble. What I'm trying to do is make a random number game where the player has to pick a number 1 through 10 and if it's wrong then try again and have the program record how many times they guessed (but not add to the number of guess when a number has been picked previously or if the number that was picked is outside the specified range) I have already worked out the logic code and was trying to make a class specifically for just the logic and a class that is specifically just for the I/O interface. But I'm having one heck of a time. Any input or tips will be very appreciated and I will provide the code that I already have below:
This is the Logic class where I want it to handle all the logic
package guessapp;
import java.util.HashSet;
import java.util.Scanner;
public class GuessLogic {
public static int Logic() {
HashSet<Integer> hs = new HashSet<>();
int GuessLogic = (int) (Math.random() * 10 + 1);
Scanner keyboard = new Scanner(System.in);
int A;
int guess;
int NumGuess = 1;
do {
guess = keyboard.nextInt();
if (hs.contains(guess)) {
A = 1;
return A;
}
if (guess < 0 || guess > 10) {
A = 2;
return A;
}
if (guess == GuessLogic) {
A = 3;
return A; // this will stop the loop
} else if (guess < GuessLogic) {
NumGuess++;
A = 4;
return A;
} else if (guess > GuessLogic) {
NumGuess++;
A = 5;
return A;
}
hs.add(guess);
} while (true);
}
public static int getGuess() {
int guess;
Scanner keyboard = new Scanner(System.in);
guess = keyboard.nextInt();
return guess;
}
}
And this is the class I want to handle all I/O interface
import java.util.HashSet;
import java.util.Scanner;
public class GuessApp {
public static void main(String[] args) {
int r, w, y;
r = GuessLogic.Logic();
w = GuessLogic.getGuess();
int NumGuess;
NumGuess = 2;
System.out.print("Enter a guess: ");
if (r == 1) {
System.out.println("You have already entered this number");
}
if (r == 2) {
System.out.println("Your guess is out of the specified range. Please try again.");
}
System.out.println("Your guess is " + w);
if (r == 3) {
System.out.println("You got it right!! Congrats!! Total Number of Guesses: " + NumGuess);
} else if (r == 4) {
System.out.println("You are wrong!!! Hint: Guess Higher, Guess number: " + NumGuess);
} else if (r == 5) {
System.out.println("You are wrong!!! Hint: Guess Lower, Guess number: " + NumGuess);
}
}
}

Below is the modified codes. There are some general ideas:
GuessLogic should be used as an instance rather than a static class. Because you need GuessLogic to save the operations and the target number.
The while loop should be coded in main. Because GuessLogic is responsible for logic only.
The elements is Set is unique, so there is no need to count how many different number by yourself.
GuessApp:
public class GuessApp {
public static void main(String[] args) {
int r, w, y;
GuessLogic guessLogic = new GuessLogic();
while(true){
System.out.print("Enter a guess: ");
w = guessLogic.getGuess();
r = guessLogic.Logic();
if (r == 1) {
System.out.println("You have already entered this number");
continue;
}
if (r == 2) {
System.out.println("Your guess is out of the specified range. Please try again.");
continue;
}
System.out.println("Your guess is " + w);
if (r == 3) {
System.out.println("You got it right!! Congrats!! Total Number of Guesses: " + guessLogic.getNumber());
break;
} else if (r == 4) {
System.out.println("You are wrong!!! Hint: Guess Higher, Guess number: " + guessLogic.getNumber());
} else if (r == 5) {
System.out.println("You are wrong!!! Hint: Guess Lower, Guess number: " + guessLogic.getNumber());
}
}
}
}
GuessLogic:
public class GuessLogic {
HashSet<Integer> hs = new HashSet<>();
int number = (int) (Math.random() * 10 + 1);
public int getNumber(){
return hs.size();
}
public int Logic(int guess) {
if (hs.contains(guess)) {
return 1;
}
if (guess < 0 || guess > 10) {
return 2;
}
if (guess == number) {
return 3; // this will stop the loop
} else if (guess < number) {
// just add to the set. The set will guarantee that there is no repetitive item.
hs.add(guess);
return 4;
} else if (guess > number) {
hs.add(guess);
return 5;
}
return -1;
}
public int getGuess() {
int guess;
Scanner keyboard = new Scanner(System.in);
guess = keyboard.nextInt();
return guess;
}
}

Blackjack program score total

So in my blackjack program when each game ends the program asks you if you would to play again. My main problem right now is that when the new game is started the score counter just keeps adding the new score to the old score instead of resetting to 0. Im not really sure how to fix it. Here are the two classes where the problem is.
Player class:
public class Player{
private String name;
private Card[] hand; // from 2 - 5 cards allowed
private int cardCount,
chips;
public Player()
{
hand = new Card[5];
chips = 5;
cardCount = 0;
}
public Player(String n){
hand = new Card[5];
name = n;
chips = 5;
cardCount = 0;
}
public void acceptACard(Card c){
hand[cardCount] = new Card();
hand[cardCount] = c;
cardCount++;
}
public void showHand(int startCard)
{
for (int i = startCard; i < cardCount; i++){
System.out.print(hand[i] + "\t"); // displays one card from hand
}
}
public int calcScore(){
int cardScore =0;
int total = 0;
boolean hasAce = false;
for(int i=0; i < cardCount; i++){
cardScore = hand[i].getValue();
if (cardScore >=11 && cardScore <=13)
cardScore = 10;
else if (cardScore == 14){
cardScore = 11;
hasAce = true;
}
total += cardScore;}
if (total > 21 && hasAce == true)
total -= 10;
return total;
}
public void incrementChips(){
chips ++;
}
public void decrementChips(){
chips --;
}
public int getChips(){
return chips;
}
}
BlackJack class:
public class BlackJack {
private Player human,
computer;
private Deck deck = new Deck();
Scanner scan = new Scanner(System.in);
public BlackJack(){
human = new Player("");
computer = new Player ("");
}
public void playGame()
{
int cardTotal = 0;
String answer, answer2;
deck.shuffle();
do{
for ( int i = 0; i < 2; i++)
{
human.acceptACard(deck.dealACard());
computer.acceptACard(deck.dealACard());
}
System.out.print(" Human hand: ");
human.showHand(0);
System.out.print("\n Computer hand: ");
computer.showHand(1);
System.out.println("\nThe computers total points: " +
computer.calcScore());
System.out.println("Players total points: " + human.calcScore());
if(human.calcScore() == 21 && computer.calcScore() < 21)
System.out.println("You win");
else if (computer.calcScore() == 21 && human.calcScore() < 21)
System.out.println("Computer wins!");
else if (computer.calcScore() == 21 && human.calcScore() == 21)
System.out.println("Tie!");
else if (human.calcScore() < 21)
do{
System.out.println("\nWould you like to hit or stay? Type hit or" +
" stay.");
answer = scan.nextLine();
if(answer.equals("hit"))
{
dealHand();
human.calcScore();
computer.calcScore();
cardTotal ++;
}
}while(cardTotal < 4 && answer.equals("hit"));
determineWinner();
System.out.println("Would you like to play again? Enter yes or no: ");
answer = scan.nextLine();
}while(answer.equals("yes"));
reportGameStatus();
}
public void dealHand(){
int i = 2; int j =2;
human.acceptACard(deck.dealACard());
System.out.println("New card: ");
human.showHand(i++);
while(computer.calcScore() < 17){
computer.acceptACard(deck.dealACard());
System.out.println();
System.out.println("Computer's new card: ");
computer.showHand(j++);
}
}
public void determineWinner(){
System.out.println("\nThe computers total points: " +
computer.calcScore());
System.out.println("Players total points: " + human.calcScore());
if (computer.calcScore() > human.calcScore() && computer.calcScore()<22){
System.out.println("Computer wins!");
computer.incrementChips();
human.decrementChips();
}
else if (human.calcScore() > computer.calcScore() && human.calcScore()
<22){
System.out.println("You win!!");
human.incrementChips();
computer.decrementChips();
}
else if (human.calcScore() == computer.calcScore() )
System.out.println("Tie!");
else if (human.calcScore() > 21){
System.out.println("You bust! The Computer wins!");
computer.incrementChips();
human.decrementChips();
}
else if (computer.calcScore() > 21){
System.out.println("The Computer busts! You win!");
computer.decrementChips();
human.incrementChips();
}
}
public void reportGameStatus(){
if(computer.getChips() > human.getChips())
System.out.println("Overall winner is the computer!");
else if(human.getChips() > computer.getChips())
System.out.println("You are the overall winner!");
}
}
Any help would be much appreciated.

I think here is your problem:
if(answer.equals("hit"))
{
dealHand();
human.calcScore();
computer.calcScore();
cardTotal ++;
}
Instead of making new Objects you use the old ones and keep their inner state. That means your construktor is not used a second time and therefore your score, hand, chips are not resetted.
How about trying this:
if(answer.equals("hit"))
{
dealHand();
Player human = new Player();
human.calcScore();
Computer computer = new Coputer();
computer.calcScore();
cardTotal ++;
}
Also you have to make a new Deck everytime you start a new game:
Deck deck = new Deck();
Edit:
If you want to keep your chipCount place it in an Object wich will be initialiset in the constructor of your Blackjack class. After that call a function chipcount.setChipcount(chips); if you want to change the chipCount. Obvisoulsly your chipcount-object should have a getter getChipcounts() as well to get the actual chipCount.
It could look like this:
public BlackJack(){
human = new Player("");
computer = new Player ("");
ChipCount chipCount = new Chipcount(0);
}
here is how your object would be:
class ChipCount{
int chipCount;
public ChipCount(int startChips){
this.chipCount = startchips;
}
public void setChips(int chipsToAdd){
this.chipCount = this.chipcount + chipsToAdd;
}
public int getChips(){
return chipCount;
}
}
Before youre asking. Of course you could make two objects (ChipCountPlayer & ChipCountComputer). Also there is the possibility of giving setChips & getChips another argument like:
class ChipCount{
int chipCountPlayer;
int chipCountComp;
public ChipCount(int startChips){
this.chipCountPlayer = startchips;
this.chipCountComp = startchips;
}
public void setChips(int chipsToAdd, String player){
if(player.equals("player")){
this.chipCountPlayer = this.chipcountPlayer + chipsToAdd;
} else if (player.equals("computer")){
this.chipCountComp = this.chipcountComp + chipsToAdd;
}
}
public int getChips(String player){
if(player.equals("player")){
return chipCountPlayer;
} else if (player.equals("computer")){
return chipCountcomp;
}
}
}
that would be the other solution :P
PS: I am not fond of blackjack, does the computer even have chips? Anyway you could replace the comp with another player if you want to further extent your programm :D

Having trouble with this java code - supposed to print and count number of heads and tails in a random coin toss

So as the title says, I have to use a class file and also a main method java file that calls the class file and prints out the starting coin face, as well as 40 more coin face flips. I also need to have 2 counters that count the number of heads and number of tails. Here is my code for my class file and main method file. The problem I'm having is that whenever I run it, it always prints out that heads has 0 count and tails as 40 counts.
Class File:
import java.util.Random;
public class CoinToss
{
private String sideUp;
public CoinToss()
{
Random randomNum = new Random();
int number = randomNum.nextInt();
if(number%2 == 0)
sideUp = "heads";
else
sideUp = "tails";
System.out.println(sideUp);
}
public void toss()
{
Random randomNum = new Random();
int number = randomNum.nextInt();
if(number%2 != 0)
{
sideUp = "heads";
}
else
{
sideUp = "tails";
}
System.out.println(sideUp);
}
public String getSideUp()
{
return sideUp;
}
}
Main Method File
public class CoinTossDemo
{
public static void main(String[] args)
{
int headsCount = 0;
int tailsCount = 0;
System.out.print("The Starting side of the coin is: ");
CoinToss coin = new CoinToss();
System.out.println();
for(int x = 0; x < 40; x++)
{
System.out.print("The next side of the coin is: ");
coin.toss();
System.out.println();
if(coin.equals("heads"))
{
headsCount++;
}
else
{
tailsCount++;
}
}
System.out.println("The amount of heads that showed up is: " + headsCount);
System.out.println();
System.out.println("The amount of tails that showed up is: " + tailsCount);
}
}
Please help, thanks in advance.

Currently you're comparing the CoinToss coin object with the String value heads and that's why its always going to the else part.
I can see that you are setting the result of the current coin toss to sideUp(which is a String). Thus you need to compare that with the heads in the if.
if(coin.getSideUp().equals("heads")) { // getSideUp() returns the sideUp value
headsCount++;
} else {
tailsCount++;
}

You are assigning your answer to side up property so get that value coin.getSideUp()
for (int x = 0; x < 40; x++)
{
System.out.print("The next side of the coin is: ");
coin.toss();
System.out.println();
if (coin.getSideUp().equals("heads")) // use the side up property
{
headsCount++;
}
else
{
tailsCount++;
}
}

Making a lottery application: fill array with random numbers

I am making a lottery application in Java. My problem is that I think everything is in place and it (the IDE) is telling me that "int lotteryNumbersCount = Eck_LotteryClass.getLotteryNumbers().length;" needs to be static. So I change it to a static int and then I have to change it again in my class. Problem is when I finally run it I get all 0's for my random lottery data. Please help me find the errors in my ways. Total newb here and I've been looking online here but I want to try to figure it out without just copying code somewhere.
Eck_LotteryClass
import java.util.Random;
public class Eck_LotteryClass {
//instance field
private int lotteryNumbers [];
//Create random lottery numbers method array
public int [] getRandomNumbers(){
lotteryNumbers = new int [5];
Random r = new Random();
for(int i = 0; i < 5; i++)
lotteryNumbers[i] = r.nextInt(10);
return lotteryNumbers;
}
public int compareNumbers(int[] usersNumbers) {
int matchedNums = 0;
if (usersNumbers.length == lotteryNumbers.length) {
for (int i = 0; i < lotteryNumbers.length; i++) {
if (usersNumbers[i] == lotteryNumbers[i]) {
matchedNums ++;
}
}
}
return matchedNums;}
// Display the random lottery numbers for the user
public int [] getLotteryNumbers() {
return lotteryNumbers;
}
}
Eck_LotteryTester
import java.util.Scanner;
import java.util.Arrays;
public class Eck_LotteryTester{
public static void main(String[] args) {
Eck_LotteryClass lottery = new Eck_LotteryClass();
int lotteryNumbersCount = Eck_LotteryClass.getLotteryNumbers().length;
System.out.println("The Pennsylvania Lottery\n");
System.out.println("There are " + lotteryNumbersCount
+ " numbers in my lottery, they are 0 through 9. "
+ "See if you can win big CASH prizes!!!\n");
// Asks the user to enter five numbers.
Scanner keyboard = new Scanner(System.in);
int numbers[] = new int[lotteryNumbersCount];
for (int index = 0; index < numbers.length; index++) {
System.out.print(String.format("Enter Number %d: ", index + 1));
numbers[index] = keyboard.nextInt();
}
// Display the number of digits that match the randomly generated
// lottery numbers.
int match = lottery.compareNumbers(numbers);
if (match == lotteryNumbersCount) {
// If all of the digits match, display a message proclaiming the
// user a grand prize winner.
System.out.println("\nYOU WIN, GO SEE D. LEETE FOR YOUR GRAND PRIZE!!!");
} else {
System.out.println("\nThe winning numbers are " + Arrays.toString(Eck_LotteryClass.getLotteryNumbers()) +
"\nYou matched " + match + " number(s).");
}
}
}

Change
int lotteryNumbersCount = Eck_LotteryClass.getLotteryNumbers().length;
to
int lotteryNumbersCount = lottery .getLotteryNumbers().length;
and you won't have to change the methods signature to static. Also you'll be talking about the same variable.
Also change
// Display the random lottery numbers for the user
public int [] getLotteryNumbers() {
return lotteryNumbers;
}
to
// Display the random lottery numbers for the user
public int [] getLotteryNumbers() {
return getRandomNumbers();
}
So the array gets initialized. And changing the signature of
public int [] getRandomNumbers
to
private int [] getRandomNumbers
wouldn't hurt

package New_list;
import java.util.Scanner;
import java.util.Random;
public class Lottery {
private static Scanner scan;
public static void main(String[] args) {
System.out.println("\t\t\tWelcome to Harsh Lottery System.\n");
Random random = new Random();
int lottery_win_1 = random.nextInt(10);
// Print Lottery winning number...1 :P
// System.out.println(lottery_win_1 + "\n");
int lottery_win_2 = random.nextInt(10);
// Print Lottery winning number...2 :P
// System.out.println(lottery_win_2 + "\n");
boolean loop = true;
while(loop){
System.out.println("\t\t\tEnter your 2 Digit Lottery number.\n");
scan = new Scanner(System.in);
int lottery_no = scan.nextInt();
if ((lottery_no >= 0) && (lottery_no <= 99)) {
int lottery_no_1, lottery_no_2;
if (lottery_no > 9) {
lottery_no_1 = lottery_no / 10;
lottery_no_2 = lottery_no % 10;
} else {
lottery_no_1 = 0;
lottery_no_2 = lottery_no;
}
if ((lottery_win_1 == lottery_no_1)
