Moving around a 2D array

Read the attached file.
1.start with ‘X’ in array[0][0]
2.Move to Right if end is reach and still Right, ‘X’ appears on left side.
3.Move to Left if end is reach and still Left, ‘X’ appears on Right side.
4.Move to Up if end is reach and still Up, ‘X’ appears from bottom.
5.Move to Down if end is reach and still Down, ‘X’ appears from top.
6. If there is an obstatcle in the way, program beep

Code:

import java.util.*;

	public static void main(String[] args)throws IOException{
