Convert a string of numbers into an array

Question

Answer 1

You should split the string once and store the array somewhere.

Here you are iterating up to the number of characters in the string, not the number of space-separated numbers.

int [] n1 = new int [numbers.length()];
for(int n = 0; n < numbers.length(); n++) {
   n1[n] = Integer.parseInt(numbers.split(" ")[n]);
}

Change to:

String[] parts = numbers.split(" ");
int[] n1 = new int[parts.length];
for(int n = 0; n < parts.length; n++) {
   n1[n] = Integer.parseInt(parts[n]);
}
