(二)算法之假设修正法

假设修正法：

/**

      * 1.判断三个数的最大值

      * a = 23

      * b = 12

      * c = 34

      */

     @Test

     public void test() {

           int a = 23;

           int b = 21;

           int c = 34;

           int m = 0;//将m设为一个擂台，让这三个数在擂台上PK

           //比武开始，谁赢了谁留在擂台上

           if(a > m) m = a;

           if(b > m) m = b;

           if(c > m) m = c;

           System.out.println("abc中最大的是："+m);

     }

      // 判断润年

     

     @Test

     public void test01(){

           int year = 2000;

           boolean is = false;

           if(year%4==0) is = true;

           if(year%100==0) is = false;

           if(year%400==0) is = true;

           System.out.println("是否是闰年"+is);

     }
