java - 程序将按降序输出三个整数

Question

该程序旨在提示用户输入三个整数，将这些整数存储在三个单独的变量中，并按降序(从最高值到最低值)输出这三个整数。

import java.util.Scanner;

public class ProgramToo
{
public static void main(String [] args)
{
  Scanner kbd = new Scanner(System.in);

  System.out.println("Enter the first number:");
  int num1 = kbd.nextInt();

  System.out.println("Enter the second number:");
  int num2 = kbd.nextInt();

  System.out.println("Enter the three number:");
  int num3 = kbd.nextInt();

  int result = largeSmall(num1, num2, num3);
  System.out.println(result);
  }
  public static int largeSmall(int one, int two, int three)
  {
  if(one > two && two > three)
  {
     System.out.println(one + " " + two + " " + three);
  }
  else if(two > one && one > three)
  {
     System.out.println(two + " " + one + " " + three);
  }
  else if(three > two && two > one)
  {
     System.out.println(three + " " + two + " " + one);
  }
  else
  {
     System.out.println(one + " " + three + " " + two);
  }
  return largeSmall(one, two, three);
  }
  }       

当我运行这个程序时，它输出整数一百万次并崩溃。为什么？

Answer 1

你的解决方案确实是过度设计的。只需做这样的事情:

public static void main(String [] args)
{
  Scanner kbd = new Scanner(System.in);

  System.out.println("Enter the first number:");
  int num1 = kbd.nextInt();

  System.out.println("Enter the second number:");
  int num2 = kbd.nextInt();

  System.out.println("Enter the three number:");
  int num3 = kbd.nextInt();

  Integer[] arr = new Integer[3]
  arr[0] = num1;
  arr[1] = num2;
  arr[2] = num3;
  Arrays.sort(arr, Collections.reverseOrder());
  System.out.println(arr[0] + " " + arr[1] + " " + arr[2]);
}
