I am attempting to read an infinite amount of numbers input on the same line from user (separated by a space) and print the square of all values above 0 - all without using for loops.

For example...

Input:

1 2 3 4 -10 -15

Output:

30

Below is the code I have so far:

```
ArrayList<Integer> numbers = new ArrayList<Integer>();

    //insert into array if > 0
    int x = sc.nextInt();
    if(x > 0){
        numbers.add(x);
    }

    //square numbers array
    for (int i = 0; i < numbers.size(); ++i) {
        numbers.set(i, numbers.get(i) * numbers.get(i));
    }

    //sum array
    int sum = 0;
    for(int i = 0; i < numbers.size(); ++i){
        sum += numbers.get(i);
    }
    System.out.println(sum);

```

As you can see I am just scanning one input from the user as i'm not sure how to tackle storing infinite input. Furthermore, I am using for loops for my two equations.

Thanks
