Hi,

Doing homework for a programming course and we're given a 1000 digit
String which we have to convert to integer, load into an array, and
then find the largest product of a group of 5 integers. I know I can
use the Integer.parseInt( ) method but I wanted to play around with
the toInt() method. From what I can gather, it's essentially the same
thing...basically the opposite to the toString() method. So, I've
tried a few things and I can't get it to work the way I want.

Here's a stripped down version of what I'd like to do.

public class thousand_digit_string
{
 public static void main(String[] args)
 {
	int oneBigInt=0;
	String num = "450";
	oneBigInt = toInt(num);
}

How can I use it properly?

I've also seen mention of

static int toInt(java.lang.String str, int defaultValue)

and 

NumberUtils.toInt()

Can someone kind soul give me some pointers?
