我启动了一个play框架项目，需要通过java类main方法运行它。这是我的java类。

import java.util.Scanner;

public class Tester {
    public static void main(String[] args) {
        System.out.println("Menu");
        System.out.println("Press A to add");
        System.out.println("Press D to Delete");
        System.out.println("Press V to View");
        System.out.println("Press G to Start Server");
        Scanner scanner = new Scanner(System.in);
        System.out.print("Please Enter Your Select: ");
        String select = scanner.nextLine();

        switch (select){
            case "A":
                // add method
                break;
            case "D":
                // delete method
                break;
            case "V":
                // view method
                break;
            case "G":
                // start server
                break;
            default:
                System.out.println("Something went wrong!");
        }
    }
}

启动服务器的方法应该来点什么？？？
