How can I remove while (true) from my loop in Java?

Question

I heard that using while (true) is a bad programming practice.

So, I wrote the following code to get some numbers from the user (with default values). However, if the user is of type -1, then he will exit the program for them.

How should this be written then without any time (true)? Can I come up with a condition to make the while loop go off, which will be caught right away without continuing until the next iteration?

Here's how I have it now:

 public static void main(String[] args)
    {
        System.out.println("QuickSelect!");

        while (true)
        {
            System.out.println("Enter \"-1\" to quit.");

            int arraySize = 10;
            System.out.print("Enter the size of the array (10): ");
            String line = input.nextLine();
            if (line.matches("\\d+"))
            {
                arraySize = Integer.valueOf(line);
            }

            if (arraySize == -1) break;

            int k = 1;
            System.out.print("Enter the kth smallest element you desire (1): ");
            line = input.nextLine();
            if (line.matches("\\d+"))
            {
                k = Integer.valueOf(k);
            }

            if (k == -1) break;

            List<Integer> randomData = generateRandomData(arraySize, 1, 100);

            quickSelect(randomData, k);
        }
    }
