The problem here is that you've switched requirements again.  Your first 
problems statement was:

 > find the largest product of a group of 5 integers.

And those aren't integers, they're digits.  So it all depends still on 
what you are trying to do.  If you just want the digits:

String str = "30420729485092847590";
int[] x = new int[ str.length ];  // *cough*

	for (int i = 0; i < str.length(); i++)
	{
	  x[i] = str.charAt(i) - '0';
	}

No need to parse a single digit.
