Introduction java programming information

Check Game
With checking user input, we compare each field in the game against the corresponding field in the solution. The result is stored in a two dimensional boolean array. The selected number is also set to 0 (meaning no number is selected). All observers are notified that the model has changed with the corresponding UpdateAction.
View & Controller
There is not much to say about the view part, only the structure of the panels. The controllers react to user input and implement changes to the model. The model notifies it has been changed. The view responses to this notification and updates. These updates of the view are limited to changing colors and changing the number of a field. There is no rocket science involved.
WORD GAME
The view also is the entry point of this application; the Word game  class contains the main method. This class builds up the user interface by creating a JFrame and placing WordgamePanel and ButtonPanel inside this frame. It also creates the Game class, and adds WordgamePanel and ButtonPanel as observers to it.
Wordgame Panel and Fields
WordgamePanel contains 9 sub panels each containing 9 fields. All sub panels and fields are placed in aGridLayout of 3x3. Each sub panel represents a region of a Sudoku game, and is primarily used for drawing a border visually separating each region. They also get the wordgameController added to them, which is in charge of processing user input by mouse.


ButtonPanel
ButtonPanel contains two panels with a titled border. The first panel contains three buttons. Button New for starting a new game, button Check for checking user input, and button Exit for exiting the application. The second panel contains 9 toggle buttons placed inside a button group. This way, they react like radio buttons. Clicking one of these toggle buttons will set the corresponding selected number in the Game class.
Here are a number of ideas to improve the above program,

• 
  Modify the program so that the user can resign so that the computer will print the correct answer.
  
• 
  Modify the program so that you can play the game for multiple words at a time.
