java 输入3个数a,b,c，按大小顺序输出的实例讲解

import java.util.scanner;

public class lianxi34 {

public static void main(string[] args) {

  scanner s = new scanner(system.in);

  system.out.println( "请输入3个整数：" );

  int a = s.nextint();

  int b = s.nextint();

  int c = s.nextint();

   if (a < b) {

   int t = a;

   a = b;

   b = t;

  }

   if (a < c) {

   int t = a;

   a = c;

   c = t;

  }

   if (b < c) {

   int t = b;

   b = c;

   c = t;

  }

  system.out.println( "从大到小的顺序输出:" );

  system.out.println(a + " " + b + " " + c);

}
