Question

my string contains Integer separated by space:

String number = "1 2 3 4 5 "

How I can get list of Integer from this string ?

Answer 1

You can use a Scanner to read the string one integer at a time.

Scanner scanner = new Scanner(number);
List<Integer> list = new ArrayList<Integer>();
while (scanner.hasNextInt()) {
    list.add(scanner.nextInt());
}
