A Fast method of Converting String to int array in Java?

[codighack]

Hi,

I am using Java V7. Is there a fast way to convert String to int array in Java?

The Given format is "4 343 234 -24" and so on. Spaces between the numbers, amount of numbers is known beforehand just as is the range within the numbers are

long[] array = new long[length];            
for (int i = 0; i < length - 1; i++) {
    array[i] = Integer.parseInt(n.substring(0, n.indexOf(' ')));
    n = n.substring(n.substring(0, n.indexOf(' ')).length() + 1);
}
array[length - 1] = Integer.parseInt(n);
