My code is not stopping the iteration where i use the do while loop, i wanted to only iterate when the secondThrow is not the same as the firstThrow and not a number 7????? help
import java.util.Scanner;

die2.roll();
}
private int getSum()
{
int sum = die1.getNumber()+die2.getNumber();
return sum;
}

{
rollDice();
int firstThrow = getSum();
int secondThrow = getSum();
//for (int i; i )
if(firstThrow == 7 || firstThrow == 11)

System.out.println("Input the amount of "+scan);
prompt_from_user = scan.nextLine();
if (prompt_from_user == "YES" || prompt_from_user == "yes");
{
}
This is the part that's wrong
do
{
rollDice();
secondThrow = getSum();
System.out.println("SeconndThrow is: "+secondThrow);
System.out.println("FirstThrow is: "+firstThrow);
if (secondThrow == firstThrow)

}
else if (secondThrow == 7)
{
System.out.println("You rolled a 7 You Lose! ");
}
}
while (secondThrow != firstThrow || secondThrow != 7);
I wanted to only iterate when the > secondThrow is not the same as > > the firstThrow and not a number 7
Read the sentence and realise then that your condition should implement an AND instead of an OR

I am currently creating a pig game, and have most functions working.
I need the code to work where if player 1 decides to stop rolling, and player two decides to stop rolling, the game will loop back until one player reaches 20 points. Currently, the code ends after 1 run through.

}
else //if either one is 20 or greater
{
return; //go to main method and finish
}
}
}
My GameContinue() function is what i created to go loop back to PlayerOne.
public static void GameContinue() {
if (playerTotal < 20 && playerTwoTotal < 20) { //if neither players totals or 20 or greater
gameOver = false;
PlayerOneTurn(); //go back to playerOne
}
else //if either one is 20 or greater
{
return; //go to main method and finish
}
}
I know calling PlayerOneTurn(); will not loop it back to the start of the main method. I've tried calling all three methods again like this.
public static void GameContinue() {
if (playerTotal < 20 && playerTwoTotal < 20) { //if neither players totals or 20 or greater
gameOver = false;
PlayerOneTurn(); //go back to playerOne
PlayerTwoTurn();
GameContinue();
}
else //if either one is 20 or greater
{
return; //go to main method and finish
}
}
Obviously that just caused a butload of errors. How should i go about having my code continue to loop back until the if statement in GameContinue() is met?
As Ecto has commented, you could use a while loop in the main function. It is shown here:
public static void main(String[] args) {
while (GameContinue()) {
PlayerOneTurn();
PlayerTwoTurn();
}
if (playerTotal >= FINAL_SCORE) {
System.out.print("Current Score: Player 1 has " + playerTotal);
System.out.print(", Player 2 has " + playerTwoTotal);
System.out.println("");
System.out.println("Player 1 wins!");
}
if (playerTwoTotal >= FINAL_SCORE) {
System.out.print("Current Score: Player 1 has " + playerTotal);
System.out.print(", Player 2 has " + playerTwoTotal);
System.out.println("");
System.out.println("Player 2 wins!");
}
}
Now obviously this would be an error as GameContinue() is a void method. To combat this you can change GameContinue() to this:
public static boolean GameContinue() {
if (playerTotal < 20 && playerTwoTotal < 20) {
gameOver = false;
return true;
} else {
return false;
}
}
This would solve your problems and your code is minimally changed.
Ok, so I have created the following program. It is not yet complete but when the code comes to the end (y or n part) and the user decides to try again they don't get the option to enter a new bet it just uses the one entered from the first time.
(Please comment if you need help about understanding the code or thinking it might be hard for other people to understand)
import java.util.*;
public class Lab15 {
static Scanner kin = new Scanner(System.in);
public static void main(String[] args) {
double money = 1000;
System.out.println("Welcom To Craps You Start With 1000$!!!");
int play = 1; //variable to cancel whole loop
char yesNo; //if user wants to continue playing or not
while(money > 0 && play == 1) {
System.out.print("Please Enter The Amount You Want To Bet: ");
double bet = kin.nextDouble();
while((bet <= money || bet > 0)) {
do { //loop to test if the bet is legit
if(money < bet || bet < 0) {
System.out.print("Sorry Invalid Bet; Please Enter A Legitimant Bet: ");
bet = kin.nextDouble();
}
} while(bet > money || bet < 0);
money -= bet;
System.out.println("You Have Bet $" + bet + " And Have " + money + " Left");
int die1 = (1 + (int) (6 * Math.random()));
int die2 = (1 + (int) (3 * Math.random()));
int sum = die1 + die2;

int loopBreak = 0; //to break do while loop bellow
do {
if(yesNo == 'y') { //take above yes no to restart loop or not
System.out.println("Restarting...");
loopBreak += 1;
continue;
}
else if(yesNo == 'n') {
System.out.println("Thank You For Playing");
play -= 1; //to cancel whole program
break;
}
else {
System.out.println("Please Enter 'y' Or 'n'");
}
} while(loopBreak == 0);
if(play == 0) {
break;
}
}
}
}
}
Its all about nested while loop don't stop when it needed. Its like this
while(money > 0 && play == 1) {
System.out.print("Please Enter The Amount You Want To Bet: ");
double bet = kin.nextDouble();
while((bet <= money || bet > 0)) {
...
do {
if(yesNo == 'y') { //take above yes no to restart loop or not
System.out.println("Restarting...");
loopBreak += 1;
continue;
}
else if(yesNo == 'n') {
System.out.println("Thank You For Playing");
play -= 1; //to cancel whole program
break;
}
else {
System.out.println("Please Enter 'y' Or 'n'");
}
} while(loopBreak == 0);
if(play == 0) {
break;
}
}
}
After you get answer 'y' you don't break the nested while and program never get the
while(money > 0 && play == 1) {
--> System.out.print("Please Enter The Amount You Want To Bet: ");
--> double bet = kin.nextDouble();
//because below while loop continues to loop
while((bet <= money || bet > 0)) {
...
}
}
part. Anyways corrected code is here(i tried every possibility and it worked)
import java.util.*;
public class Lab15 {

System.out.print("Please Enter The Amount You Want To Bet: ");
double bet = kin.nextDouble();
while((bet <= money || bet > 0)) {
do { //loop to test if the bet is legit
if(money < bet || bet < 0) {
System.out.print("Sorry Invalid Bet; Please Enter A Legitimant Bet: ");
bet = kin.nextDouble();
}
} while(bet > money || bet < 0);
money -= bet;
System.out.println("You Have Bet $" + bet + " And Have " + money + " Left");
int die1 = (1 + (int) (6 * Math.random()));
int die2 = (1 + (int) (3 * Math.random()));
int sum = die1 + die2;
System.out.println("You Rolled " + die1 + " and " + die2 + " totaling " + sum);
System.out.print("Do You Want To Play Again(y) Or Not(n): ");
yesNo = kin.next().charAt(0);
int loopBreak = 0; //to break do while loop bellow
do {
if(yesNo == 'y') { //take above yes no to restart loop or not
System.out.println("Restarting...");
loopBreak++;
continue;
}
else if(yesNo == 'n') {
System.out.println("Thank You For Playing");
play--; //to cancel whole program
break;
}
else {
System.out.println("Please Enter 'y' Or 'n': ");
}
} while(loopBreak == 0);
if(play == 0 || loopBreak == 1) {
break;
}
}
}
}
}
Have a good day!
Another solution is to use labeled breaks/continues https://docs.oracle.com/javase/tutorial/java/nutsandbolts/branch.html
However it should be used sparingly (or not at all). You probably can simplify it in some other way.
package test.test;
import java.util.Scanner;
public class Lab15 {
static Scanner kin = new Scanner(System.in);
public static void main(String[] args) {
double money = 1000;
System.out.println("Welcom To Craps You Start With 1000$!!!");
int play = 1; // variable to cancel whole loop
char yesNo; // if user wants to continue playing or not
//Labeled <-----------------
start: while (money > 0 && play == 1) {
System.out.print("Please Enter The Amount You Want To Bet: ");
double bet = kin.nextDouble();
while ((bet <= money || bet > 0)) {
do { // loop to test if the bet is legit
if (money < bet || bet < 0) {
System.out.print("Sorry Invalid Bet; Please Enter A Legitimant Bet: ");
bet = kin.nextDouble();
}
} while (bet > money || bet < 0);
money -= bet;
System.out.println("You Have Bet $" + bet + " And Have " + money + " Left");
int die1 = (1 + (int) (6 * Math.random()));
int die2 = (1 + (int) (3 * Math.random()));
int sum = die1 + die2;
System.out.println("You Rolled " + die1 + " and " + die2 + " totaling " + sum);
System.out.print("Do You Want To Play Again(y) Or Not(n)");
yesNo = kin.next().charAt(0);
int loopBreak = 0; // to break do while loop bellow
do {
if (yesNo == 'y') { // take above yes no to restart loop or not
System.out.println("Restarting...");
loopBreak += 1;
//Labeled continue <-----------------
continue start;
} else if (yesNo == 'n') {
System.out.println("Thank You For Playing");
play -= 1; // to cancel whole program
break;
} else {
System.out.println("Please Enter 'y' Or 'n'");
}
} while (loopBreak == 0);
if (play == 0) {
break;
}
}
}
}
}
I am doing a task I was assigned in my Java programming course and I'm quite new to Java. Everything runs fine in the program as long as you don't trigger the do while statement, that's when it starts to loop out of control saying 'You rolled: 7 You lose'.
import java.util.Scanner; //Importing the java.util class Scanner
public class Craps {
private Die die1;
private Die die2;
public Craps() {
die1 = new Die();
die2 = new Die();
}
private void rollDice() {
die1.roll();
die2.roll();
}
private int getSum() {
return die1.getNumber() + die2.getNumber();
}
private int getSum2() {
return die1.getNumber() + die2.getNumber();
}
public void playRound() {
rollDice();
int sum = getSum();
int sum2 = getSum2();
System.out.println("You rolled: " + sum);
if (sum == 7 || sum == 11) {
System.out.println("You Win");
}
if (sum == 2 || sum == 3 || sum == 12) {
System.out.println("You Lose");
} else if (sum == 4 || sum == 5 || sum == 6 || sum == 8 || sum == 9 || sum == 10) {
System.out.println("Establishing the point, Re-rolling...");
rollDice();
sum2 = getSum2();
do {
if (sum2 == 7) {
System.out.println("You rolled: " + sum2);
System.out.println("You lose");
}
if (sum2 == sum) {
System.out.println("You rolled: " + sum2);
System.out.println("You win!!!");
}
}
while (sum2 != sum || sum2 != 7);
}
}
public static void main(String[] args) {
Craps game = new Craps();
System.out.println("Welcome to the game of Craps!!!");
System.out.println("Rules: ");
System.out.println("Rolling a 7 or 11 will win you the game");
System.out.println("Subsequently rolling 2, 3, or 12 will lose you the game");
System.out.println("If you roll a 4, 5, 6, 8, or 10 you will 'Establish the point'");
System.out.println("Establishing the point allows you to set a new winning number and reroll");
System.out.println("When you establish the point, the goal is to not roll a 7 and instead roll");
System.out.println("the established number, rolling after establishing a point 7 now will");
System.out.println("result in a loss");
String ans = null;
Scanner scan = new Scanner(System.in);
do {
game.playRound();
ans = scan.nextLine();
}
while (ans.equalsIgnoreCase("Yes"));
}
}
EDIT My Die class
import java.util.Random;
public class Die {
private int number;
private Random generator;
public Die() {
generator = new Random();
roll();
}
public int getNumber() {
return number;
}
public void roll() {
number = generator.nextInt(6) + 1;
}
}
sum and sum2 are never updated inside your do/while loop, so once you get into the loop, you're never going to get out of it.
do {
if (sum2 == 7) {
System.out.println("You rolled: " + sum2);
System.out.println("You lose");
}
if (sum2 == sum) {
System.out.println("You rolled: " + sum2);
System.out.println("You win!!!");
}
}
while (sum2 != sum || sum2 != 7); // Condition never changes
Another nice pattern is taking advantage of return to short circuit:
while (true) {
rollBabyRoll();
if (getSum2() == 7) {
// Log
return;
else if (getSum() == sum) {
// Log
return;
}
}
Bonus
As another little tip, I don't know Craps at all, but you may want to think about using recursion instead.
private void reroll(int sum) {
rollDice();
int sum2 = getSum2();
if (sum2 == 7) {
// Do something
else if (sum2 = sum) {
// Do something
} else {
reroll(sum);
}
}
I am doing a project to make a user login, then ask the user to select which game to play, then write the code for the game. I have done everything apart from being able to choose to between the 2 games. Any tips on how to do this would greatly help!

You should create for every game a class and create a start method there to start the game based on your user input for example:
System.out.println("Please type 1 for game 1 or 2 for game2:");
action = Integer.parseInt(br.readLine());
if (action == 1)
{
System.out.println("\nYou have chosen to game 1");
Game1 game1 = new Game1();
game1.start();
}
else if (action == 2)
{
System.out.println("\nYou have chosen game 2");
Game2 game2 = new Game2();
game2.start();
}
This code is based on your code.
Bob, I just check through your code.
According to what I saw, my understanding of your question is that "After user login and selected the game type, both game would run subsequently, while you only want to run the game user chose".
If that is the case, then the solution is easy:
Take the games code parts out from the
while(again){
// In this block, only keeps your user choice code.
}
block. That block would be just for getting user's choice.
After that choice block, you get your users' choice from variable "action". Now you just need to add a if block as below:
if(action == 1){
// Put your Rock,Paper,Scissors game code here, as user chose 1
//******************************
//Rock,Paper,Scissors
//********************************
...
}else if(action == 2){
// Put your Pick Up Sticks game code here, as user chose 2.
//***********************
//Pick Up Sticks
//***********************
...
}
As you only want to run one game at a time, you need a "IF" condition to tell the code which game to run.
So just "IF" is enough, but separating the "Choice" part and "Game" part, from my opinion, would make the code more simpler and easier to be understood.
My variable names are pretty stupid near the bottom but that's not the point. Line 110 says that I'm making an else statement without the if and I'm nearly certain the if is there. Please help in any way you can.
Thank you

Try removing the semicolons in if(chili >= 20); and else (ghost >= 20);.
public static boolean peppers(int chili, int ghost)

{

System.out.println(" YOU WIN!!!");
}
else if (ghost >= 20)

}

}
replace
else (ghost >= 20);
with
else if (ghost >= 20)
and remove the semicolons after the if-statement.
