IOW "give me teh codez". No.

Post your code here along with all compiler messages and/or exceptions as well as a descritpion of what it is suppossed to do and what it actually does and exactly how they differ, and we will help you to correct your own code, but you are going to have to do it.

i hava this code. working perfect.
but i want explanation for it.
I dont know event handling in this .

How snake is moving here?

wht does update and Paint methods do here?

The concept "homework" involves: doing it yourself. Obviously you missed that.

IOW, Someone else already gave me the code, but I can't defend it to my instructor.

Try writing some code. Try doing your homework and you might actually learn something.

I agree :)
b.move(75, 50);    i.move(68, 90);   p.move(68, 130);   X.move(73, 170);

what is the use of "move" method here?

there is no method like "move" in AWT.?

pleas explain....

Using someone else's code for your homework is called "cheating". Nobody here is going to help you cheat.
Write your own code and you will get help.

sory.

I m not cheating any body.
i m trying to learn my self

i found it from a book.

is it cheating to learn from any body who knows well?

>>i found it from a book.
>>is it cheating to learn from any body who knows well?

I don't believe that code comes from a book. If that person ``who knows well' writes such code, full with magic numbers, and no comments at all - just to give a few examples of bad practice - and then publishes this rubbish, then I wouldn't dare to say that this person ``knows well'.

The reason why you're not getting much help is because you're copying and pasting code and asking us to explain it to you. You're not showing any effort at all.

We can help explain to you concepts, for example what's a method, and help you debug your code, but you have to actually try to write the code.

Furthermore, oftentimes writing code helps you answer a lot of your questions (e.g. where does the move() method come from, how does it work).

what is the use of "move" method here?

Here you need to use the API doc. It will explain to you what the move method does.
Find the object class that move is a method for and go to that class's API doc.

back = getImage(getCodeBase(), "screan.gif");
i am using the netbean the snake game above mentioned , in which folder or location i put the image screen.gif plzzzzzzz some reply
