Weight loss plan

Title:

Enter the number of weeks to display today’s weight loss plan

Analysis:

• Keyboard entry A week number is received in a variable;

• uses the switch statement for judgment;

• outputs the corresponding statement.

Practice:

The code is as follows (example):

public class Demo3 {
    public static void main(String[] args) {
    //不爱生姜不吃醋
        // 键盘录入一个星期数，用一个变量接收；
        Scanner sc=new Scanner(System.in);
        System.out.println("请输入星期数：");
        int week=sc.nextInt();

        // 使用switch语句进行判断；
        switch(week){
            case 1:
                System.out.println("今天的计划是：跑步！");
                break;
            case 2:
                System.out.println("今天的计划是：爬山！");
                break;
            case 3:
                System.out.println("今天的计划是：游泳！");
                break;
            case 4:
                System.out.println("今天的计划是：骑自行车！");
                break;
            case 5:
                System.out.println("今天的计划是：拳击！");
                break;
            case 6:
                System.out.println("今天的计划是：健美操！");
                break;
            case 7:
                System.out.println("今天的计划是：休息！");
                break;
            default:
                System.out.println("输入的星期数有误！");
                break;
        }
    }
}
