![Instructions Picross 3.0<br>This is the final version of the Picross code development and your task is to produce a program that will allow the user to solve the puzzle. Feel free to take provided solutions from<br>previous labs and assignments to incorporate into this final product. In addition to the functionalities required in the previous working version of the code, add the following:<br>1. Class PicrossPuzzle<br>1. In addition to the solution 2D array, a second 2D array (call it entered) needs to become part of a PicrossPuzzle object. solution holds the key or the secret<br>picture the user is trying to solve; entered holds the current set of inputs entered by the user. solution is filled by information read from a data file, while entered<br>is initially all Os (i.e., user has not clicked on any button yet). Scan through the existing methods and constructors and update any of these where the entered array<br>may need to be initialized or updated.<br>2. A void toggleCell(int i, int j) method which flips the value in the entered array at row i, column j. That is, if entered[i][j] currently holds a 0, this<br>method turns it into a 1, and vice versa.<br>3. Aboolean puzzleSolved () method which returns true if the puzzle has been solved, that is, the solution and the entered arrays contain the same exact<br>values at each row and column. If they differ by at least one element, it returns false.<br>4. Aint [] [] getEntered () getter method which returns the entered 2D array; this could be used in the Controller class to collect the entered array and<br>display the puzzle board as game progresses.<br>5. A void resetEntered () setter method which initializes the entered array back to all Os.This method will be handy when a user has solved a game, or when the<br>user gives up and chooses to play a new game before the current one is solved.<br>6. Any additional private and public methods needed.<br>2. Class PicrossPuzzlePool<br>o No changes needed from the most previous working version (Lab 5).<br>3. GUI and Controller class<br>1. Add an event handler so that when one of the grid pane buttons is clicked, the cell changes from white to black and black to white; and also updates(toggles) the array<br>element in the PicrossPuzzle object.<br>2. Every time a button is clicked, check whether the puzzle has been solved or not. If the puzzle is solved, notify the user using an Alert box with an appropriate<br>message. Displaying the filename when the puzzle is solved is optional. If the puzzle is not solved, the GUI waits for the next button click from the user.<br>3. Add a new button, Start Over, to allow the user to refresh the entries back to their original state, i.e., resets the game. Note that this does not present a new puzzle but<br>keeps the current puzzle blanking out all previous entries, if any. Add a method to handle this button being clicked.<br>](https://s3.us-east-1.amazonaws.com/storage.unifolks.com/qimg-008/008_4crzz0-io040n20.png)
