Hello, I recently struck a trouble spot in which I am attempting to return an array from a public method. How would I go about doing this? I, as well, want to have an argument for a method to be able to recieve an array and manipulate/copy its contents. Pointers seem such a desirable thing to have right now. Thank you.

I hope this helps.

  public void passArray(int [] list)  {  }  public int [] returnArray()  {	int [] list = new int[10];	return list;  }

You do have pointers in Java. All Objects (including arrays) are referred to by a reference type which (other than lack of pointer arithmetic) is the same as C's pointer type. Try creating an object, passing it into a function, and modifying the object in the function; after the function returns, the modifications will have been made to the original object.

Ah I understand - it seems easy enough; much thanks to you both.
