Array out of bounds

I am new at Java and I am not sure if I am posting at the right place. Please let me know if I am not. I am trying to transfer a 2 dimension array to a text file but get the following runtime error:

java.lang.ArrayIndexOutOfBoundsException: 2
at Parts.writeArray(Parts.java:25)
at Parts.main(Parts.java:13)

Here is the code I have so far:



Can someone please help me?

Thanks!

The problem is due to the fact that your 2D array is not 'square' but the inner loop in this pair


assumes it is square. It is easily rectified. You just need to make sure that the inner loop indexes over the length of the row being processed i.e. parts[row].length and not parts.length .
