我如何通过回答是或否来重复这个程序？

Question

这是我的密码

我尝试了DO WHILE方法，但它也不起作用：

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

public class Main
{
    public static void main(String[] args) {
    String name;
    int choice;
    int time;
    Console cons = System.console();
    if (cons==null)
    {

        System.out.println("");
        return;
    }

我在这里开始做，但它不起作用

    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+".");
    }
}

}或者可能我只是把那些括号搞错了，你能帮我确定是什么问题吗？我是Java新手

尝试使用intent再次调用main()方法，或者您可以先尝试调用main()，而不使用intent，以节省一些行空间...
