I want to know more about run() and start() methods, how they work. I am confused.Can anybody help me?

Question

class DrawImage extends Thread {
public void run() {
System.out.println("drawing image");
}}
class PlayMusic extends Thread {
public void run(){
System.out.println("playing music");
}}
class MyGame{
public static void main(String[ ] args) {
DrawImage diObj= new DrawImage();
diObj.start(); //diObj.run();
PlayMusic pmObj= new PlayMusic();
pmObj.start(); //pmObj.run();
}}

Answer 1

I mean to ask about the priority..in which order those methods works in thread execution..

Answer 2

if I'm not wrong ..we use run() method in interfaces while start() to start a thread

Answer 3

threads in parellel execution execute randomly..unless priority is set by using setPriority() method.
