扫描仪可用于提示用户询问他/她是否要继续。

您甚至可以跟踪编号。掷骰子的次数。

import java.util.Scanner;

public class DiceGame {

public static int attempt = 1;

/**

* @param args

* the command line arguments

*/

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

int dice1 = (int) (Math.random() * 6 + 1);

int dice2 = (int) (Math.random() * 6 + 1);

int sum = dice1 + dice2;

while (true) {

System.out.println();

System.out.println("Rolling dice for " + attempt + " time!");

dice1 = (int) (Math.random() * 6 + 1);

dice2 = (int) (Math.random() * 6 + 1);

sum = dice1 + dice2;

System.out.println("Roll: total = " + sum);

if (sum == 2 || sum == 3 || sum == 12) {

System.out.println("Sorry with a " + sum + " you loose :(!");

System.out.println();

break;

} else if (sum == 7 || sum == 11) {

System.out.println("With a " + sum + " you win :)!");

System.out.println();

break;

}

System.out.println();

System.out.println("Do you wish to continue? Press 'y' for YES or ANY key for EXIT");

if (!scanner.next().equalsIgnoreCase("y")) {

break;

}

attempt++;

}

System.out.println("Thanks for playing dice game, you rolled the dice " + attempt + " times!");

}

}

EDIT: 如果要在总和为4 5 6 8 9 10时自动掷骰子，则不再需要Scanner，即用户输入是否继续。

这是相同的解决方案。

public class DiceGame {

public static int attempt = 1;

public static void main(String[] args) {

int dice1 = 0;

int dice2 = 0;

int sum = 0;

while (true) {

System.out.println();

System.out.println("Rolling dice for " + attempt + " time!");

dice1 = (int) (Math.random() * 6 + 1);

dice2 = (int) (Math.random() * 6 + 1);

sum = dice1 + dice2;

System.out.println("Roll: total = " + sum);

if (sum == 2 || sum == 3 || sum == 12) {

System.out.println("Sorry with a " + sum + " you loose :(!");

System.out.println();

break;

} else if (sum == 7 || sum == 11) {

System.out.println("With a " + sum + " you win :)!");

System.out.println();

break;

// this will roll the dices automatically

// when sum is 4, 5, 6, 8, 9 or 10

} else {

System.out.println();

System.out.println("With " + sum + " dices are rolled again automatically!!");

attempt++;

}

}

System.out.println("Thanks for playing dice game, you rolled the dice " + attempt + " times!");

}

}
