我是编码的初学者，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，而我差不多已经完成了... 我想循环我的整个程序，但是我遇到了问题。 关于如何循环程序的任何建议？或使用我正在使用的方法进行更正...任何帮助将不胜感激：）

我假设这是您要寻找的东西，但是在使用和使用此代码之前，请考虑以下几件事：代码的编写方式并未最大限度地利用面向对象的Java。如果该代码具有多个类，则该代码更易读，并且通常更好。 Main类只能用于初始化另一个类或一组类。好的，现在输入代码。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{

初恋： -main方法通常应具有最低限度的代码。主要方法实际上应该只是初始化程序并启动它，因此将其中的一些内容移至构造函数或其他地方
无论如何，您正在做的事情是功能确定的，但请尽量避免养成不良习惯：通过从其他方法内部调用方法，将代码分成较小的块。这将使调试容易得多，并使其他人更容易阅读。但是，您正在做一些不错的事情，例如为变量赋一个体面的名称，并且您是一个初学者，因此使东西具有功能性是第一步，因此您做得很好。
关于您的问题，当您真正想在程序中循环一个关键方法时，您想循环整个程序，而程序本身并不需要循环，这并不是要实现的目标。一个程序无法循环自身，因为要循环执行什么（只有另一个程序可以这样做）？
因此，您需要做的是将初始化内容从main方法中移除，然后将其放入可以从main方法中调用的其他方法中。在这个新方法中，在游戏初始化代码内创建while循环，并在初始化类的实例后调用main方法中的方法（main方法是静态的，因此必须在内部将类创建为变量）。
执行以下操作：
//Make a new class containing just the main method
public static void main(String[] args){
//Substitute Class for the name of your class and initiate it as below
Class myClass = new Class():
//
myClass.initiate();
}
//Then in your actual action class
public void initiate(){
while(condition){
//call the shuffle method inside a while loop, if you want to initiate inside too
//then have your array building stuff in a method you call here too
buildArray();
shuffle();
}
}
希望这对兄弟有帮助

惰性选项1：将main（）的内容包装在while（true）{ main内部的任何内容}
懒惰选项2：在要重新启动的末尾创建一个新线程，即new Thread（new Runnable（）{public void run（）{main（null）;}}）。start（）;
任务可能是做什么的：在末尾添加一些问题，询问您是否要再次玩游戏，如果可以，请以某种方式再次循环游戏。
我不得不问，为什么是假的加载屏幕？
