Java 似乎找不到我的构造函数，我不知道出了什么问题。抛出 InterruptedException 有问题吗？任何帮助将不胜感激，谢谢！

    package gameloop;

    import javax.swing.*;

    public class GameLoop extends JFrame {
        private boolean isRunning;
        public int drawx = 0;
        public int drawy = 0;

        public void GameLoop() throws InterruptedException{   
            setSize(700, 700);
            setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            setLocationRelativeTo(null);
            setVisible(true);

            while(isRunning){
                doGameUpdate();
                render();
                Thread.sleep(1);
                if (isRunning){
                    GameLoop();
                }
            } 
        }

        private void doGameUpdate() {
            GameUpdate GU = new GameUpdate();
        }

        private void render() {
            Draw dr = new Draw();
        }

       public static void main(String[] args) {
            GameLoop GL = new GameLoop();
        }
    }

A constructor is named exactly like its class, and has no return type. If you provide a return type, even void, you create a method called GameLoop. What you are looking for is

public GameLoop()

rather than

public void GameLoop()

You need public GameLoop() constructors don't have return types

That's not a constructor - this is:

public GameLoop() throws InterruptedException

A constructor can not have a return type (void in your code), if you add one, Java will interpret it it as a normal method - even if it's called exactly like the class!

You constructor has a return type so it is treated as any other method
