Hey guyz , ive got below program :

import java.awt.Graphics;
import java.awt.Image;
public class BJ1 extends java.applet.Applet
{
	
	Image mypic;
	public void init()
	{
		  mypic = getImage(getCodeBase(), "C01.jpg");
	}
	
	public void paint(Graphics screen)
	{
		int	iWidth =71 ;//71 int iWidth =mypic.getWidth(this);
		int iHeight=96;  //96 int iHeight=mypic.getHeight(this);


		int xPos = 10;
		screen.drawImage(mypic, xPos,10, this);
	}
}

However , as i try to run , i got below error :

Exception in thread "main"

How are you trying to execute your applet? The error message says you were trying to use the java command. Applets are executed in a browser by coding an <APPLET tag in some html and having the browser read the html page and then the class file.

If you want to execute a class with the java program you need to have a main(String[] args) method in it.

how can i implement the main thread into my program so it can run on Java ?

Do you want it to run as an applet or as an application?
An applet runs from an html page.
To make a desktop application out of your code requires a major rewrite.

Do you want an applet or an application?
For an applet, write an html page with the applet tag.

To make a desktop application out of your code requires a major rewrite.

First it needs a GUI. Extend JFrame instead of applet
Add a constructor to fill the frame with the components you want (see below).
Move the code from the init method to the constructor
Add a main(String[] args) method that calls the constructor.

Move/change the paint method to be the paintComponent method in a JPanel.
Add that panel to the frame.
