Question

我正在制作一个Craps java程序而且我在添加＆＃34时遇到了一些问题;你想再玩一次吗？＃34;最后的声明。如果你能帮助我，我将不胜感激！此外，我必须计算用户赢/输多少游戏的计数器不能正常工作。如果你看到问题，请告诉我！

import java.util.Scanner;
public class Lab5 {
    static int dice2;
    public static void main(String[] args) {
        //variables
        int dice1;
        int dice2;
        int numWins = 0;
        int numLosses = 0;

        //Call the welcome method
        welcome();

        //fetch random numbers

        /*
        * **************************************************************
        *welcome method
        *welcome user
        *no parameters
        *no return
        ****************************************************************
        */
    }
    public static void welcome() {
        System.out.println("Welcome to a Lucky (for me) Dice Game! \nFEELING LUCKY?!? Hope you brought lots of CASH!");{
        }

        int die1 = (int) (Math.random()*6 + 1);
        int die2 = (int) (Math.random()*6 + 1);
        int dice = die1 + die2;
        System.out.println("Roll: total = " + dice);
        int numWins = 0;
        int numLosses = 0;
        if (dice == 7 || dice == 11){
            System.out.println("Woah!!! With a: "+dice+ " You WIN!!!!!!!!");
            numWins++;
        }
        else if (dice == 2 || dice == 3 || dice == 12){
            System.out.println("Sorry, with a "+dice+" You lose:(");
            numLosses++;
        }

        while (dice != 0){
            int die3 = (int) (Math.random()*6 + 1);
            int die4 = (int) (Math.random()*6 + 1);
            int dice2 = die3 + die4;
            System.out.println("Roll: total = "+dice2);

            if (dice2 == 2|| dice2 == 3 || dice2 == 12){
                System.out.println("Sorry, with a "+dice2+" You lose:(");
                numLosses++;
                dice = 0;
            }
            else if (dice2 == 7 || dice2 == 11){
                System.out.println("Woah!!! With a: "+dice2+ " You WIN!!!!!!!!");
                numWins++;
                dice = 0;
            }
            {
                System.out.println("So far you have won " + numWins +
                " times and lost " + numLosses + " times, ");

                {


                }
            }
        }
}}

这是我运行时的输出：

Welcome to a Lucky (for me) Dice Game! 
FEELING LUCKY?!? Hope you brought lots of CASH!
Roll: total = 2
Sorry, with a 2 You lose:(
Roll: total = 8
So far you have won 0 times and lost 1 times, 
Roll: total = 10
So far you have won 0 times and lost 1 times, 
Roll: total = 8
So far you have won 0 times and lost 1 times, 
Roll: total = 3
Sorry, with a 3 You lose:(
So far you have won 0 times and lost 2 times,

只有胜负后才能说出反击。我该如何解决这个问题？

Answer 1

要重复某些内容，请使用循环，例如while循环或do-while循环，如果您不确定循环的manny时间。要获取用户输入，请使用已导入的Scanner对象。 do-while循环结构将类似于......

do {
  // code to do inside of the loop
} while (somethingIsTrue);

您需要使用一些sentinel变量来更改循环，然后在while布尔检查内部进行测试。它可以是一个String，在这种情况下，你可以在while的布尔检查中使用String equals(...)或equalsIgnoreCase(...)方法。

因此，请考虑使用System.out.print(...)在do代码块的末尾提示输入，使用Scanner获取输入，然后在while布尔测试中测试该输入。
