Comment

To ensure that a method is not able to modify a Collection passed as

an argument, we have to make the Collection read only.

We can make a read only collection by using

Collections.unmodifiableCollection(Collection c) method.

This will make sure that any operation to change the collection will

throw UnsupportedOperationException.

public class Puzzle4 {
  public static void main(String [] args) {
    ___________________________________
    int y = 1;
    int x = 0;
    int result = 0;
    while (x < 6) {
      ___________________________
      ___________________________
      y = y * 10;
      _________________
    }
    x = 6;
    while (x > 0) {
      _________________
      result = result + ___________________
    }
    System.out.println("result " + result);
  }
}
class ___________ {
  int ivar;
  ________ ______ doStuff(int _________) {
    if (ivar > 100) {
      return _________________________
    } else {
      return _________________________
    }
  }
}
