string to int

String numStr = "173 2643 123 1 6";

String numStr = "173 2643 123 1 6";
// First we split it into an array
String[] numStrArray = numStr.split(" ");
// What this does is makes numStrArray be:
// {"173", "2643", "123", "1", "6"}
// Now we need to go through the array,
// converting the strings to ints:
int len = numStrArray.length;
int[] numArray = new int[len];
for(int i = 0; i < len; i++) {
    String val = numStrArray[i]
    numArray[i] = Integer.parseInt(val);
}
// Now numArray is:
// {173, 2643, 123, 1, 6}
