    The public void fill method is what i want to be in jMenu
    Can you explain what you are trying to do?
    Menus usually contain menu items.

    sure...
    the fill method that i have is
    public void fill(Graphics g) {
    		System.out.println("press 1 for oval:");
    		int l = 0;
    		switch(l){
    		case 1: g.drawOval(x+1, y+1, size-2, size-2);
    	 break;
    		case 2: g.drawRect(x+1, y+1, size-2, size-2);
    		break;
    		//g.drawRect(x+1, y+1, size-2, size-2);
    		}

    if I just put g.drawRect(x+1, y+1, size-2, size-2);

    the code is working perfectly fine. Now what i want is give user the option of choosing the shape of the snnake either rect or oval. to do that i want to make a menu and from that menu user will decide the shape.

    Have you read the tutorial about how to create menus?
    That would be a good place to start. Go to this site and Find Menu:

    What does the user need permission for?

    Sorry, I have no idea what your problem is.

    let's see if I can make it more clear. so the following code gives the snake rectangular shape.
    g.drawRect(x+1, y+1, size-2, size-2);

    what I want is make some kind of option for user to choose whatever shape they want to have either rectangle or oval: some thing like this:
    public void fill(Graphics g) {
    		System.out.println("press 1 for oval:");
    		int l = 0;
    		switch(l){
    		case 1: g.drawOval(x+1, y+1, size-2, size-2);
    	       break;
    		case 2: g.drawRect(x+1, y+1, size-2, size-2);
    		break;
    		//g.drawRect(x+1, y+1, size-2, size-2);
    		}
    you understand now ???

    what I want is make some kind of option for user to choose whatever shape
    There are many GUI components that would allow the user to choose a shape.
    A menu item is one.
    You need to look at the choice of components and chose one that will work with your program.

    I know that my friend but I am not too familier with GUI that's why I am asking for help... Hard for me to figure out which component is good for my code
