*BOLDED METHODS ARE THE PARTS THAT NEEDS CODING*

Main topics: GUIs

Program Specification:

You are to finish the following Graphical Mine Sweap program:

You are given the following Complete class MyJButton:

import javax.swing.*;

public class MyJButton extends JButton

{

private static final long serialVersionUID = 2L;

public final int row;

public final int col;

public MyJButton(String text, int row, int col)

{

super(text);

this.row = row;

this.col = col;

}

}

You are also given the following Partial class MineSweapPart:

import javax.swing.*;

import java.awt.*;

import java.awt.event.*;

public class MineSweapPart extends JFrame

private static int actualMinesLeft = MineSweapPart.MINES;

private static final String FLAGGED = "@";

private static final String MINE = "M";

Rules and Requirements:

- Your game must play equivalently to the original Windows MineSweap game

- You may NOT remove any of the supplied or implied (via the comment blocks) functionality in these classes.

- You must implement ALL of the implied (via the comment blocks) functionality in these classes.

- You MAY implement additional functionality / features in these classes.
