java - 如何循环整个程序？

Question

我是编码初学者，所以我想在我想创建的简单程序/游戏中寻求帮助

我正在尝试创建一个简单的争夺游戏，我几乎已经完成了...... 我想循环我的整个程序，但我遇到了问题.. 关于如何循环我的程序有什么建议吗？或用我正在使用的方法进行更正...任何帮助将不胜感激:)

public static void main(String[] args) throws InterruptedException {

我假设这就是您正在寻找的内容，但在您获取和使用此代码之前，请考虑以下几件事:您的代码编写方式并未最大限度地利用 Java 的面向对象特性。如果这段代码有多个类，那么它通常会更清晰、更好。 Main 类只能用于初始化另一个类或类组。好的，现在来说说代码。这应该可以解决问题:

    import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class Shuffle {
    public static void main(String[] args) {
        startGame();
    }
    public static void shuffle(String input,String rword) throws InterruptedException{
        Scanner scanner = new Scanner(System.in);

        List<Character> characters = new ArrayList<>();
        for(char c:input.toCharArray()){
            boolean scword = characters.add(c);
        }
        StringBuilder scrmbldword = new StringBuilder(input.length());
        while(!characters.isEmpty()){
            int randPicker = (int)(Math.random()*characters.size());
            scrmbldword.append(characters.remove(randPicker));
        }

        // Game loads the game xD
        System.out.print("\rLoading");
        Thread.sleep(500);
        System.out.print("\rLoading.");
        Thread.sleep(500);
        System.out.print("\rLoading..");
        Thread.sleep(500);
        System.out.print("\rLoading...");
        Thread.sleep(500);

        Thread.sleep(500);
        System.out.print("\rLoading.....");
        Thread.sleep(100);
        System.out.print("\rCompleted");

        // Game introduces itself to the user.
        Thread.sleep(2000);
        System.out.println("\rWelcome to Scramble PT!");
        Thread.sleep(1000);
