Getting the source of a mouse click

Question

I have a Battleship game I am programming and have only one problem. What the program does is to have one array that is visible that will look like the ocean. The array consists of JLabels with icons on them. I have a second array that is not visible that is JLabels with icons that has all hits and then I place the ship icons over them where the ships are located. I am having trouble with comparing the JLabel that was clicked on with the location of that label so I can access the hidden array to get the icon at that location and place it in the location of the JLabel that was clicked on. The code seems to work down to when I click on a JLabel the mouseclicked method is called and I see that it is going through the loops fine, but the if statement for comparison never equates to true. Here is my code and the code I am referencing is in the mouseclicked method:
import javax.swing.*;
import java.awt.event.*;

import java.util.*;

I hope someone can help me. Thanks.

Answer 1

in your first post, on the top right, next to the orange envelope, there is a paper with a pencil in it. That is what you click to edit.
And for the code button, you have to highlight everything you want in "code mode" and then press it.
Alternatively, you can just put (code) and the beginning of your code and one at the end, except replace the ( and ) with { and }.
