Here is my assignment: In Chapter 5, you created a lottery game application. Create a similar game using check boxes. For this game, generate six random numbers, each between 0 and 30 inclusive. Allow the user to choose six check boxes to play the game. (Do not allow the user to choose more than six boxes.) After the player has chosen six numbers, display the randomly selected numbers, the player ’ s numbers, and the amount of money the user has won, as follows: Matching Numbers Three matches Four matches Five matches Six matches Zero, one, or two matches Award ($) 100 10,000 50,000 1,000,000 0
Additional requirements are as follows:
• Add a menu bar to the program with a File menu.
• In the File menu, add a submenu (JMenuItem) called About.
• When the user clicks on the About menu item, display a
JOptionPane message dialog that contains your name, your
course, the section number, and MEID.
The primary issue I am having is with the limiting of checkboxes, I cannot seem to find examples of this in the text or anywhere online (except in javascript and html, which obviously do not help me here.) I have posted my code below. Please note that I am only looking for answers to the limit on check boxes at the moment the rest of the code I can complete myself.

final int HIGHEST_VAL = 30;
final int LOWEST_VAL = 1;
final int BOXES_CHECKED = 6;
final int WIDE = 400;
final int TALL = 400;
//set random number generator
int numR = ((int) (Math.random() * 100) % HIGHEST_VAL + LOWEST_VAL);
int numR2 = ((int) (Math.random() * 100) % HIGHEST_VAL + LOWEST_VAL);
int numR3 = ((int) (Math.random() * 100) % HIGHEST_VAL + LOWEST_VAL);
