JAVA if条件语句，switch多分支结构，与逻辑运算符

import java.util.Scanner;
public class Test{
    public static void main(String[] args){
        Scanner in    =    new Scanner(System.in);
        System.out.println("请输入学生的成绩：");
        int num    =    in.nextInt();
        if(num==100){
            System.out.println("满分！");
        }
        else if(num>60 && num<100){
            System.out.println("合格！");
        }
        else if(num==60){
            System.out.println("刚好合格！");
        }
        else{
            System.out.println("不合格");
        }
    }
}

        //switch只支持整型(int)或字符类型（char）
        switch(num){
            case 1:
