如何在java中等待并关闭命令提示符

import java.util.Scanner;

public class WaitAndClose {
    public static void main(String[] args) {
        System.out.println("请输入任意字符后按回车键关闭命令提示符：");
        Scanner scanner = new Scanner(System.in);
        String input = scanner.nextLine();
        System.out.println("输入的字符为：" + input);
        System.out.println("关闭命令提示符...");
        System.exit(0);
    }
}
