Hi I'm doing a project in java.It is the game othello.It was all going well till i got an ArrayOutOfBoundsException. the array is this buttons[9][9]; If you dont know othello it's a board game with an 8x8 board.

The Exact error is "ArrayOutOfBoundsException: 9" and give the lines which the error is which are:

1->

if (the_buttons[rows][colunm+1].getIcon().equals(BG)== true &&
                  the_buttons[rows+1][colunm].getIcon().equals(BG)== true &&
	  the_buttons[rows][colunm-1].getIcon().equals(BG)== true && 
	  the_buttons[rows-1][colunm].getIcon().equals(BG)== true )
	       {
		dialog(2);
		return false;
	        }		 
    return true;

2->

if(checkIfOccupied() == false && checkForSq()== true )
		   {
		          if(checkIflegal()==true)
		            {
			 if (checkWhichPlayer()==true)
          			     { 							                          the_buttons[rows][colunm].setIcon(r);
				 checkForward(r,Y)  ;
				 checkUpLeft(r,Y)   ;
				 checkUpRight(r,Y)  ;
			            	 checkBackwards(r,Y);
			            	 checkDownLeft(r,Y) ;
			             	 checkDownRight(r,Y);
			             	 checkDown(r,Y)     ;
			                 checkUp(r,Y)       ;
	   		     }

3->

if (cmd.equals(""+i))
	    {
	              checkforColunm(j=0,i);
	             PickButton(rows,colunm);
                            
                      }

CAN ANYONE HELP IT'S THE LAST HURDEL AND THIS NEEDS TO BE IN TOMORROW.....

you are exceeding the array's bounds.
exactly, one can't figure out what causes the error, because the manipulation is done by
your code that comes before these blocks.
check it again, either you go beyond index 8 or below index 0, good luck.

I'm Sorry to do this but I really need help with this I'm posting my project so far to see if you can help

You just forgot to mention that beside that you getting another 30 errors, not nice of you...

I'm very sorry about that this one has no errors I just complied it

did u face null pointer exception?!
u have more than one problem i guess!

no I'm trying to fix that too It's late and I just cant think.Any suggestions on either problems?

take this file, i added this line to help you,
System.out.println("This"+rows+" "+colunm); line number 730

look at the printed values, you are exceeding 9.

I know in the_buttons[2][8],[3][8],[4][8] the lines also says that the rows are -1 so [4][8] say's it's [3][8]. but I cant find why this is happening the same with the exceeding the array I tried changing the array to [8][8] but it doesn't work. I know it's something small and right in front of me i just cant see it.

line 731, adding 1 to colunm 8 makes it 9, which exceeds the array,,

Ya that seemed to work for a few buttons I'll try go through the rest Cause I need this in early tomorrow.Any suggestions on the Null pointer?
