Here is my main method, I won't include all the rest of the code as it is not necessary. However, I am trying to figure out how to print out the highest score out of the three variables: player1, player2, player3
public static void main(String[] args) {
System.out.println("Welcome to Price is Right!");
System.out.println("Player 1 are you ready to spin?");
int player1 = player();
System.out.println("Player 1 Your final score is: " + player1);
System.out.println("Player 2 are you ready to spin?");
int player2 = player();
System.out.println("Player 2 Your final score is: " + player2);
System.out.println("Player 3 are you ready to spin?");
int player3 = player();
System.out.println("Player 3 Your final score is: " + player3);
// todo..
}
Any ideas would be appreciated. I have thought about calling in a method to calculate this or using if statements, I am not sure what is the best approach.
Same as my other answer, but much simpler, using an int[] array. We store the maxScore and the corresponding maxUser as we go, so we can output them at the end:
public static void main(String[] args) {
System.out.println("Welcome to Price is Right!");
int[] scores = new int[3];
int maxScore = -1;
int maxUser = 0;
for (int i = 0; i < scores.length; i++) {
System.out.println("Player " + (i+1) + " are you ready to spin?");
scores[i] = player();
if (scores[i] > maxScore) {
maxUser = i;
maxScore = scores[i];
}
System.out.println("Player " + (i+1) + " Your final score is: " + scores[i]);
}
System.out.println("Player " + (maxUser+1) + " won with a final score of " + maxScore);
}
you can put all player's scores in an array and then find highest amongst them
List<Integer> scores = new ArrayList<>();
scores.put(player1.getScore());
scores.put(player2.getScore());
int highest = Collections.max(arrayList);
System.out.println("Highest score is: " + highest);
OR you can simply do it via IF-Else
The easiest way I can think of is using if and else statements:
if(Player1> Player2 && Playe1 > Player3){
System.out.println("Highest score was earned by Player 1 which is"+ player1);
}else if(Player2> Player3 && Playe2 > Player1){
System.out.println("Highest score was earned by Player 2 which is"+ player2);
}else{
System.out.println("Highest score was earned by Player 3 which is"+ player3);
}
How about this very compact and easily extendable solution? Your teacher would be proud! If it is too complex take a look at my other solution, which only uses an int[]
public static void main(String[] args) {
System.out.println("Welcome to Price is Right!");
int playerCount = 3;
List<Integer> scores = new LinkedList<>();
for (int i = 0; i < playerCount; i++) {
System.out.println("Player " + (i+1) + " are you ready to spin?");
scores.add(player());
System.out.println("Player " + (i+1) + " Your final score is: " + scores.get(scores.size()-1));
}
System.out.println("The maximum score is " + Collections.max(scores));
}
Instead of storing each player score in its own variable, we just collect them all in a Collection. By doing it this way we can simply change playerCount to accommodate any number of players!
And if you want to print which player won you can replace the last line with this:
int maxScore = Collections.max(scores);
for (int i = 0; i < scores.size(); i++) {
if (scores.get(i) == maxScore) {
System.out.println("Player " + (i+1) + " won with a final score of " + maxScore);
break;
}
}
Or if you want to be (very) fancy:
OptionalInt maxVal = IntStream.range(0, playerCount).reduce((a, b) -> scores.get(a) > scores.get(b) ? a : b);
maxVal.ifPresent(i -> System.out.println("player " + (i+1) + " won with a final score of " + scores.get(i)));
Considering result is your custom object it's contain marks.
First create object of comparator class like
Comparator com= comparator.comparing(Result::getMarks);
Here getMarks is your getter method and mark is your variable.
Result result = List.s stream(). Max(com).get();
You can also find minimum value using min function..

String[][] array = {{"Checkup", "60"},
{"Repairing tooth", "150"},
{"Cleaning", "30"}}; // Menu of treatments
String[] array2 = new String [10]; // New array that saves up to 10 elements(treatments)
int cost = 0;
int treatment = 0;
Scanner input = new Scanner(System.in);
System.out.println("Control" + " " + "1");
System.out.println("Repair tooth:" + " " + "2");
System.out.println("Cleaning:" + " " + "3");
int n = array.length;
for (int i=0; i<n; i++) {
for (int j=0; i<n ; j++) {
System.out.println();
treatment = input.nextInt();
if (treatment==1) {
cost += Integer.parseInt(array[i][1]);
System.out.print("Total cost so far: " + cost);
}
if (treatment==2) {
cost += Integer.parseInt(array[i+1][1]);
System.out.print("Total cost so far: " + cost);
}
if (treatment==3) {
cost += Integer.parseInt(array[i+2][1]);
System.out.print("Total cost so far: " + cost);
}
}
}
How do I move on from here? I figured that I have to store the input in the new array and exit the loop after 10 treatments or add an option to the user to print out the receipt when they're done.
The receipt needs to print all the chosen treatments along with the cost for each individual treatment. I will also need to add a variable to add a total amount for all the chosen treatments.
Here it is what you are trying to do, As the treatments are fixed so you can just index them as 0, 1, 2. One thing you can do is to make a hashmap in which you can store the treatment name and its cost (String,int) every time the user wants to enter.
Look at the code below
import java.util.*;
import java.util.HashMap;
public class treatment {
public static void main(String []args) {
String[][] array = {{"Checkup", "60"},
{"Repairing tooth", "150"},
{"Cleaning", "30"}}; // Menu of treatments
// New array that saves up to 10 elements(treatments)
HashMap<String, Integer> treat = new HashMap<String, Integer>();
int cost = 0;
int treatment = 0;
Scanner input = new Scanner(System.in);
int n = array.length;
int i =0;
char c = '\0';
do {
System.out.println("\n\nControl" + " " + "1");
System.out.println("Repair tooth:" + " " + "2");
System.out.println("Cleaning:" + " " + "3");
System.out.println("Exit: " + "-1");
System.out.println();
System.out.print("Enter treatment value (1, 2, 3): ");
treatment = input.nextInt();
if (treatment==1){
i = 0;
cost += Integer.parseInt(array[0][1]);
System.out.println("\nTotal cost so far: " + cost);
}
else if (treatment==2) {
i = 1;
cost += Integer.parseInt(array[1][1]);
System.out.println("\nTotal cost so far: " + cost);
}
else if (treatment==3) {
i = 2;
cost += Integer.parseInt(array[2][1]);
System.out.println("\nTotal cost so far: " + cost);
}
treat.put(array[i][0], cost);
} while (treatment != -1);
System.out.println("Total COst is : " + cost);
System.out.println("The treatements you opt for are:\n");
System.out.println(treat);
System.out.println("\n");
}
}
I am stuck at a part where in a game, I use while loop and to end the loop and get the results of the game, I want either "player1" or "player2" to enter "Q", and so i tried doing it like this:
if (player1.equals("Q") || player2.equals("Q")){
go = false; //go is a boolean variable
}
This doesn't seem to work as I have to enter "Q" for both player1 and player2 for the game to end, but instead I just want either of them to enter "Q" and the game would stop.
Code:
import java.util.Scanner;
public class Team {
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
System.out.println("Soccer Game Between 2 Teams");
System.out.println("Win is 2 points" + "\n" + "Loss is worth 0 points" + "\n" + "Overtime is worth 1 point");
System.out.println("Type W, O, or L" + "\n" + "Type Q to end the game");
int pointsw = 0;
int pointsl = 0;
int pointso = 0;
int pointsw2 = 0;
int pointsl2 = 0;
int pointso2 = 0;
int totalpoints = 0;
int totalpoints2 = 0;
int counter = 0;
int counter2 = 0;
boolean go = true;
System.out.println("\n" + "Enter team one:");
String phrase = keyboard.next();
System.out.println("\n" + "Enter team two:");
String phrase2 = keyboard.next();
System.out.println();
while (go) {
System.out.println("Enter " + phrase + " Result:");
String team1 = keyboard.next();
System.out.println("Enter " + phrase2 + " Result");
String team2 = keyboard.next();
if (team1.equals("W") || team1.equals("w")) {
pointsw += 2;
} else if (team1.equals("O") || team1.equals("o")) {
pointso += 1;
} else if (team1.equals("L") || team1.equals("l")) {
pointsl += 0;
}
counter++;
if (team2.equals("W") || team2.equals("w")) {
pointsw2 += 2;
} else if (team2.equals("O") || team2.equals("o")) {
pointso2 += 1;
} else if (team2.equals("L") || team2.equals("l")) {
pointsl2 += 0;
}
counter2++;
totalpoints = pointsw + pointso + pointsl;
totalpoints2 = pointsw2 + pointso2 + pointsl2;
if (team1.equals("Q") || team2.equals("Q")) {
go = false;
if (totalpoints > totalpoints2) {
System.out.println(phrase + " wins with " + totalpoints + " points");
System.out.println("It took " + phrase + " " + counter + " rounds to win");
} else if (totalpoints < totalpoints2) {
System.out.println(phrase2 + " wins with " + totalpoints2 + " points");
System.out.println("It took " + phrase2 + " " + counter2 + " rounds to win");
} else if (totalpoints == totalpoints2) {
int totalrounds = counter + counter2;
System.out.println("It is tie game between " + phrase + " and " + phrase2);
System.out.println("The game lasted till " + totalrounds + " rounds");
}
}
}
}
}
You should reorganize your code:
while (true) {
System.out.println("Enter " + phrase + " Result:");
String team1 = keyboard.next().toLowerCase();
if ("q".equals(team1)) {
break;
}
System.out.println("Enter " + phrase2 + " Result");
String team2 = keyboard.next().toLowerCase();
if ("q".equals(team2)) {
break;
}
if (team1.equals("w")) {
pointsw += 2;
} else if (team1.equals("o")) {
pointso += 1;
} else if (team1.equals("l")) {
pointsl += 0;
}
counter++;
if (team2.equals("w")) {
pointsw2 += 2;
} else if (team2.equals("o")) {
pointso2 += 1;
} else if (team2.equals("l")) {
pointsl2 += 0;
}
counter2++;
totalpoints = pointsw + pointso + pointsl;
totalpoints2 = pointsw2 + pointso2 + pointsl2;
} // loop completed
if (totalpoints > totalpoints2) {
System.out.println(phrase + " wins with " + totalpoints + " points");
System.out.println("It took " + phrase + " " + counter + " rounds to win");
} else if (totalpoints < totalpoints2) {
System.out.println(phrase2 + " wins with " + totalpoints2 + " points");
System.out.println("It took " + phrase2 + " " + counter2 + " rounds to win");
} else if (totalpoints == totalpoints2) {
int totalrounds = counter + counter2;
System.out.println("It is tie game between " + phrase + " and " + phrase2);
System.out.println("The game lasted till " + totalrounds + " rounds");
}
I'm not completely sure, but I think the issue is that after player 1 / player 2 says 'Q'
the scanner is still waiting for the next line to read.
String phrase = keyboard.next();
System.out.println("\n"+"Enter team two:");
String phrase2 = keyboard.next();//if player 1 types q this next() method must be resolved before it will continue to the logic
so add an if statement before play 2 goes asking if player 1 typed 'Q' , if so calculate scores and end game, if player 1 did not type 'Q' use else statement to continue on to player 2's turn

I've edited your code. Some errors were related to syntax, and some were possibly related to the logical flows. This should work as a base, and you can modify and improve it as you see fit:

System.out.println("-----------------------------------------");
do { // I always want the dice to roll unless "n" is selected.
System.out.println();
System.out.println("Do you wish to play? [y,n]: ");
answer = stdIn.next();
if (answer.equalsIgnoreCase("y")) {
turnCounter++;
int d1 = (int)(Math.random() * 4) + 1;
int d2 = (int)(Math.random() * 4) + 1;
int d3 = (int)(Math.random() * 4) + 1;
int d4 = (int)(Math.random() * 4) + 1;
System.out.println(d1 + "\t" + d2 + "\t" + d3 + "\t" + d4);

if (userWin < userLose) {System.out.println("You shouldn't bet money on this game...");}
System.out.println(turnCounter + " Rounds played.");
}
} while(answer.equalsIgnoreCase("y"));
}
}
Some points to note:
The game will keep running as long as the user types in 'y', since that is your condition: answer.equalsIgnoreCase("y").
I changed the win condition logic to check for at least a pair using the logical OR operator
I removed the division operator for the ratio result for win/loss and just replaced it with a display of wins:losses; This could be changed if you want it to calculate for an actual percentage or decimal value, but you have to check for cases where losses == 0 to prevent a divide by zero error
The Do-While loop should encompass all of the gameplay from start to finish, so the question that asks you to play again should go at the start or at the end of this loop (I placed it at the start)
I have been trying to figure out how to make it so players could choose to restart the game at the end, but whenever I try to restart the loop, it says
Label Game was not found
even though it is clearly shown in this code.

To keep it simple, you could just change the exit criteria:
if (!input.equals("yes")) {
break; // end the loop
}
Just a hint: it is considered a good practice to compare a literal against some variable:
if (!"yes".equals(input)) {
break; // end the loop
}
Doing the check this way will not fail with NullPointerException in case input is null, it just returns false in this case.
it's easier if you set the opposite:
if(input.equals("no")) running = false;
That way the while loop gets out cleanly and you don't need to use a cumbersome label to control your flow.
From
Branching Statements
The continue statement skips the current iteration of a for, while , or do-while loop.
You want to jump to the label 'Game' from outside of the labelled while loop,
which is not allowed.
This is the assignment that was give to me. But I can't seem to understand what is wrong with my program and how to go about fixing it. It just keeps rolling dice non-stop and freezes my JCreator. I even tried changing the NUMBER value to 10 and it still does the same thing.
I have declared all the variables. You need to add code to simulate rolling the
dice and keeping track of the doubles. Convert the algorithm below to Java and
place it in the main method after the variable declarations, but before the output
statements. You will be using several control structures: a while loop and an if-else-
if statement nested inside another if statement. Use the indenting of the
algorithm to help you decide what is included in the loop, what is included in the
if statement, and what is included in the nested if-else-if statement.
To “roll” the dice, use the nextInt method of the random number generator to
generate an integer from 1 to 6.
You are not using a doop loop correctly. You have a do-loop and while loop, not a single do-loop. In the do-loop count never increases so the loop will never end. A do loop performs the first iteration before evaluating whether to continue.

I think you understood the do-while concept wrong.
The "do {...}" part (where you roll the dice) gets executed as long as the expression inside the while brackets is true.
Move the whole "if (die1Value == die2Value)" part (up to the "counter++;" line) into the do braces, and it should run.
do
{
die1Value = generator.nextInt(6) + 1;
System.out.println("You rolled: " + die1Value);
die2Value = generator.nextInt(6) + 1;
System.out.println("You rolled: " + die2Value);
}
while (count <= NUMBER);
That first keyword do is taking the while to loop the whole block forever since the count variable is only incremented on the next block.
My advice is to remove the do:
//do
//{
die1Value = generator.nextInt(6) + 1;
System.out.println("You rolled: " + die1Value);
die2Value = generator.nextInt(6) + 1;
System.out.println("You rolled: " + die2Value);
//}
while (count <= NUMBER)
{
...
}
Since you already have a block after the while.
