是重复程序/否退出

Question

下面是我的代码：

import java.util.Scanner;
import java.io.Console;

        public class Activity2
       {
        public static void main(String[] args) {
        String name;
        int choice;
        int time;
        Console cons = System.console();
        if (cons==null)
        {
            System.out.println("");
            return;
        }
        name = cons.readLine("Enter your Name: ");
        Scanner scn = new Scanner(System.in);
        
        System.out.println("\nMenu");
        System.out.println("\n[1] Network Engineer\n[2] Software Engineer\n[3] Full Stack Developer\n[4] Technical Support");
        
        
        System.out.print("\nEnter your job(Choose a number from the menu): ");
        choice = scn.nextInt();
        System.out.print("Enter no. of hours present at work: " );
        time = scn.nextInt();
        
        
        if (choice == 1)
        {
            int gsalary = 1200*time;
            int nsalary = gsalary - (gsalary * 12 / 100);
            
            cons.printf("\nHello %s!\n", name);
            System.out.println("Your job salary as a Network Engineer is 1200 per hour.");
            System.out.println("Your gross salary for this week is "+gsalary+".");
            System.out.println("Your net salary for this weeks is "+nsalary+".");
        }
        
        if (choice == 2)
        {
            int gsalary = 800*time;
            int nsalary = gsalary - (gsalary * 12 / 100);
            
            cons.printf("\nHello %s!\n", name);
            System.out.println("Your job salary as a Network Engineer is 800 per hour.");
            System.out.println("Your gross salary for this week is "+gsalary+".");
            System.out.println("Your net salary for this weeks is "+nsalary+".");
        }
        
        if (choice == 3)
        {
            int gsalary = 600*time;
            int nsalary = gsalary - (gsalary * 12 / 100);
            
            cons.printf("\nHello %s!\n", name);
            System.out.println("Your job salary as a Network Engineer is 600 per hour.");
            System.out.println("Your gross salary for this week is "+gsalary+".");
            System.out.println("Your net salary for this weeks is "+nsalary+".");
        }
        
        if (choice == 4)
        {
            int gsalary = 500*time;
            int nsalary = gsalary - (gsalary * 12 / 100);
            
            cons.printf("\nHello %s!\n", name);
            System.out.println("Your job salary as a Network Engineer is 500 per hour.");
            System.out.println("Your gross salary for this week is "+gsalary+".");
            System.out.println("Your net salary for this weeks is "+nsalary+".");
        }
    }
}

以下是示例输出：

输入你的名字: Matsuno Chifuyu

菜单

1网络工程师

2软件工程师

3完整堆栈开发人员

4技术支持

输入您的工作(从菜单中选择)：3输入no。工作时间的百分比: 36

你好，松野千夫宇！作为一个全栈开发人员，你的工作薪水是每小时600美元。你这周的毛薪是21600美元。你这周的净薪是19008美元。

是否要输入其他员工？(是或否)

我如何做一个循环，如果回答是，程序将重新启动，如果否，程序将退出

Answer 1

要做到这一点，最简单的方法是将代码抛入循环，然后在用户输入no时中断。如下例所示：

public static void main(String[] args){
    Scanner in = new Scanner(System.in);
    while (true) {
        // put your app logic here
    
        System.out.println("Do you want to input another employee? [Y]es/[N]o");
        if (!in.next().equalsIgnoreCase("Y") {
            break;
        }
    }
}
