How does this work

[grim coyote]

import java.awt.Canvas;
import java.awt.Dimension;

import javax.swing.JFrame;

public class Shoot_better extends Canvas implements Runnable{
private boolean running = false ;
private Thread thread ;
private synchronized void start() { // starts the game loop
if(running) {
return ; }
running = true ;
thread = new Thread(this) ;
thread.start();
}
private synchronized void stop() {
if(!running)
return;
running = false ;
try {
thread.join();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.exit(1);
}
public void run() {
while(running) {
System.out.println("RUNNING") ; //GAME LOOP
}
}

public static void main(String[] args) {
  JFrame frame = new JFrame() ; 
  Shoot_better obj = new Shoot_better() ; 
  obj.setPreferredSize(new Dimension(200,200));
  obj.setMaximumSize(new Dimension(200,200));
  obj.setMinimumSize(new Dimension(200,200));
  
  frame.setResizable(false);
  frame.pack();
  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  frame.setVisible(true);
  frame.add(obj)  ;
  obj.start(); 
}

}

learning this from a guy on youtube

So basically when the code comes to the last line i.e obj.start() ;

it calls funtion start

function start then starts a thraed

how tf does this thread call the run() methhod

[hard narwhal]

It's because the obj also implements Runnable
