获取三个数据的最大值:

class Hello2 {    public static void main(String[] args) {        int a = 10;        int b = 20;        int c = 30;        int max;        if (a > b){            if (a > c)            {                max = a;            }else {                max = c;            }        }else {            if (b < c)            {                max = c;            }else {                max = b;            }        }        System.out.println("max = " + max);    }}

结果:
