第九篇 switch case 语句

package com.whs.day04;


public class SwitchDemo26 {
    public static void main(String[] args) {
        //cate  grade分数   case穿透     switch匹配一个具体的值
        char grade = 'A';
        switch (grade){
            case 'A':
                System.out.println("优秀");
                break; //终止
            case 'B':
                System.out.println("良好");
                break;
            case  'C':
            System.out.println("及格");
                break;
            case 'D':
                System.out.println("不及格");
                break;
            default:// 修饰符关键字
                System.out.println("不在评级范围");
        }
    }
}

通过 switch case 语句 输出字符

package com.whs.day04;


public class SwitchDemo27 {
    public static void main(String[] args) {
//        String name = "阿波罗";
        String name = "傻";
        switch (name){
            case "阿波罗":
                System.out.println("太阳神");
                break;
            case  "傻":
                System.out.println("猪头");
                break;
            default://以上条件都不符就执行该语句
                System.out.println("啥也不是");
        }
    }
