SUDOKU in JAVA Plz Help

Hi

I want to develop a Java program to solve Sudoku puzzles

My program must be able to:

昍ead in a puzzle (from the predefined file format ?see below)

旸isplay the unsolved puzzle

昐olve the puzzle

旸isplay the solved puzzle

File Format

The file consists of a number of integers.

The first integer signifies the size of the puzzle e.g. a 2 indicates a 4x4 puzzle, a 3 indicates a 9x9 puzzle, a 4 indicates a 16x16 puzzle and so on.

The remaining numbers are one integer for each square of the puzzle (e.g. 81 integers for a 9x9 puzzle) and should be read left to right and top row to bottom row. A zero means that the square is empty. A non-zero indicates the number in that square.
