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;
        }
    }
}

Is Java Platform Independent if then how?Is Java Platform Independent if then how?May 09, 2025 am 12:11 AM

Java is platform-independent because of its "write once, run everywhere" design philosophy, which relies on Java virtual machines (JVMs) and bytecode. 1) Java code is compiled into bytecode, interpreted by the JVM or compiled on the fly locally. 2) Pay attention to library dependencies, performance differences and environment configuration. 3) Using standard libraries, cross-platform testing and version management is the best practice to ensure platform independence.

To set up the JVM, you need to follow the following steps: 1) Download and install the JDK, 2) Set environment variables, 3) Verify the installation, 4) Set the IDE, 5) Test the runner program. Setting up a JVM is not just about making it work, it also involves optimizing memory allocation, garbage collection, performance tuning, and error handling to ensure optimal operation.
