If you're on Java8, you could do:

int[] array = Stream.of(aa).mapToInt(Integer::parseInt).toArray();

Loop through the array and convert it to int.

int []intArray = new int[strArray.length];
int i = 0;
for(String s : strArray)
  intArray[i ++] = Integer.parseInt(s);
System.out.println(Arrays.toString(intArray));

    int[] bb = new int[aa.length];
    for (int i = 0; i < aa.length; i++) {
        bb[i] = Integer.parseInt(aa[i]);
    }
