Please edit your post and wrap your code with
[code=java]
<YOUR CODE HERE>
[/code]
to get highlighting and preserve formatting.
What happens when you compile and execute the code?
If you don't understand my answer, don't ignore it, ask a question.
Re: keywords

Re: keywords
There are two assignment statements and two for loops.
Those are VERY BASIC java statements. What is your problem with them? Can you explain?

Re: keywords
I want to comment them like this //comment
but I do not know what to put, could you suggest for each one
Re: keywords
I have no idea what the assignment statements are doing because the posted code does not show what either variable is used for.
For a description of how for loops work see the tutorial:
The for Statement (The Java™ Tutorials > Learning the Java Language > Language Basics)
For how to use methods:
Defining Methods (The Java™ Tutorials > Learning the Java Language > Classes and Objects)
For ArrayList methods see the API doc:
Java Platform SE 7
