Question

I am trying to clone an array and return as an object, not an array type.
z

 public IntVector clone()
 {

     IntVector cloneVector = new IntVector(3);

     int[] newItems = new int[10];
     for(int i=0 ; i<itemCount_; ++i)
      {
      newItems[i] = items_[i];
      }

     cloneVector = newItems; // is there a way to do something like this??

    return cloneVector;
 }

Main method looks like this

  public static void main(String[] args)
  {

   IntVector vector = new IntVector(5);

   vector.push(8);
   vector.push(200);
   vector.push(3);
   vector.push(41);

   IntVector cloneVector = vector.clone();
  }

*there are two other methods which makes an array:IntVector() and puts value into array:push()

Answer 1

Declare a new constructor for IntVector which takes an int array and a count:

IntVector(int[] data, int n) {
  items_ = data.clone();
  itemCount_ = n;
}

Then you can write clone like this:

public IntVector clone() {
  return new IntVector(items_, itemCount_);
}

You can make that new constructor private if you like, so only clone can use it.
