输入三个数，从大到小排序：

import java.util.Scanner;public class Second{  public static void main(String []args)   {    int a,b,c,d;    Scanner sc = new Scanner(System.in);    System.out.println("请输入第一个数");    a =sc.nextInt();    System.out.println("请输入第二个数");    b = sc.nextInt();    System.out.println("请输入第三个数");    c = sc.nextInt();/*....<span style="color:#000099;">第一种方法</span>....*/    if(a>=b)    {      d=a;a=b;b=d;    }    if(b>=c)       {       d=b;b=c;c=d;    }    if(c>=a)      {        d=c;c=a;a=d;      }     System.out.println(a+">= "+b+">= "+c);       }}/*....<span style="color:#000099;">第二种方法</span>....*/ if(a>b)        {           if(b>c)System.out.println(a+">= "+b+">= "+c);           else{              if(a>c)System.out.println(a+">= "+c+">= "+b);               else System.out.println(c+">= "+a+">= "+b);           }        }        else        {            if(a>c)System.out.println(b+">="+a+">="+c);               else               {              if(b>c)System.out.println(b+">="+c+">="+a);                else System.out.println(c+">="+b+">="+a);        }    }
