Return to Question

I was working on a suggestion for this question, but the method, I would've suggested the OP do something similar to, seems a bit convoluted.

It's supposed to take a String input and return an array of only the integers deliminated by spaces. It does this correctly, but It feels like I may be doing some unnecessary things or there's a more succinct way to do this, such as with regex.

public static int[] getIntegers(String s) {
 int[] result;
 ArrayList<Integer> helper = new ArrayList<>();
 StringBuilder sb = new StringBuilder();
 for (int i = 0; i < s.length(); i++) {
 if (s.charAt(i) == ' ' ^ i == s.length() - 1) {
 if (i == s.length() - 1) { sb.append(s.charAt(i)); }
 if (sb.toString().length() > 0) {
 try { helper.add(Integer.parseInt(sb.toString()));
 } catch(NumberFormatException nfe) {
 // Ignore non-integers
 }
 sb.setLength(0);
 continue;
 }
 }
 sb.append(s.charAt(i));
 }
 result = new int[helper.size()];
 int i = 0;
 for (Integer n : helper) {
 result[i++] = n;
 }
 return result;
}
