java 输入3个数a,b,c，按大小顺序输出 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);
}
