Question

我需要在此问一个循环，询问玩家是否想再玩一次。如果用户说是，则重启游戏。如果他们说没有结束比赛。我一共遇到麻烦。请帮忙！

import java.util.Scanner;
public class HW4ChrisMuncher
  {
  public static void main(String[] args) 
  {
    Scanner input = new Scanner(System.in);

    double a;
    int b;

    System.out.println("Enter a number");
    double userNum = input.nextDouble();
    a = userNum;  

    Scanner input2 = new Scanner(System.in);

    System.out.println("Enter a number (no decimals!)");
    int userNum2 = input2.nextInt();
    b = userNum2;        



    double c = min(a, b);
    double d = max(a, b);
    double e = abs(a);
    double f = pow(a, b);     



    System.out.println("The minimum value of " + a + " and " + b + " is " + c );        
    System.out.println("The maximum value of " + a + " and " + b + " is " + d );
    System.out.println("The absolute value of "+ a+ " is " + e );
    System.out.println(+ a + " to the power of " + b + " is " + f );

  }

  // Returns the minimum of two numbers
  public static double min(double n1, int n2) 
  {
    double min;
      if (n1 > n2)
       min = n2;
      else
        min = n1;

      return min; 
   }

   // Return the max between two numbers
   public static double max(double n1, int n2)
   {
     double max;
       if (n1 > n2)
        max = n1;
       else
         max = n2;

       return max;
    }


   //Returns the absolute value of the two numbers
   public static double abs(double n1)
   {
     if (n1 < 0)
       return -n1;
     else 
       return n1;

   }


   public static double pow(double n1, int n2)
   {
     double f = 1;
         for (int i =0; i< n2; i++)
           {
             f = f * n1;
           }
         return f;

   }


 }

很简单！

只需抓住一个while循环并执行以下操作：

String s = "yes";
while(s.equals("yes") || s.equals("y")) {
    //whatever you want repeated
    System.out.println("Would you like to repeat?");
    s = scan.nextLine();
}

想一想。如果这个人输入“是”，那么while循环仍然是真的，所以它将从头开始。否则，如果此人输入“yes”之外的任何内容，则while循环条件将为false，并且循环将终止。

我希望有所帮助。祝你好运：）
