The grid is further subdivided into nine 3x3 boxes. The goal is to fill in the grid with digits such that one and only one of each digit 1 through 9 appear in every row, column, and box. Create a program that determines whether or not a Sudoku grid filled with numbers is a Sudoku. Import program1.zip (distributed in class) into Eclipse. As discussed in class, make sure that the program is well documented and submitted on time. The code is incomplete, you will have to write the fillGrid and evaluate methods where indicated by the statement: JOptionPane.showMessageDialog(this, "Write the necessary code to ..."); The program starts with an empty grid (See Figure 1). Enter numbers into the grid so that every row, column and 3x3 box contains every digit from 1 to 9 inclusive (see Figure 2) To enter the numbers, click the button, at the bottom of the window, with the number you wish to enter, and then click the button in the grid into which the number should be placed Instead of entering the numbers, there is also an option in the File menu (Fill Grid) that can fill in the numbers read from a file.
