Converting String Array to an Integer Array

Question

so basically user enters a sequence from an scanner input. 12, 3, 4, etc.
It can be of any length long and it has to be integers.
I want to convert the

Answer 1

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

class MultiArg {

    Scanner sc;
    int n;
    String as;
    List numList = new ArrayList();

    public void fun() {
        sc = new Scanner(System.in);
        System.out.println("enter value");
        while (sc.hasNextInt())
            as = sc.nextLine();
    }

    public void diplay() {
        System.out.println("x");
        Integer[] num = numList.toArray(new Integer[numList.size()]);
        System.out.println("show value " + as);
        for (Integer m : num) {
            System.out.println("\t" + m);
        }
    }
}

but to terminate the while loop you have to put any charecter at the end of input.

ex. input:

12 34 56 78 45 67 .

output:

12 34 56 78 45 67
