Loop with scanner

[Aron Gaspar]

What I am trying to do here is to make an array with the size asked from the user. Then fill the array with the numbers from scanner. However I am stuck, because the code just asks once, and not as many times as the array's size.

Scanner scan = new Scanner(System.in);
        System.out.println("Mekkora legyen az array?");
        int n = scan.nextInt();
        ArrayList<Integer> szam = new ArrayList<Integer>(n);
        for (int i = 0;i < n;i++);  {
            System.out.println("Mi a szám?");
            int i = scan.nextInt();
            szam.add(i);  } 
        System.out.println(szam);

I probably should do it with something else and not an if loop, but I can't figure it out.

The issue here is that you have a semicolon after your looping statement, which means the For loop has an empty body. So the for loop does nothing, and then executes your following code one time. To resolve, remove the extra semicolon.

[pedantic mode]No you aren't; you are populating a List. When it says ArrayList, it doesn't mean you are creating an array; it means the List maintains an array with all its elements in.[/pedantic mode]
