im trying to set an array objects to 0 but the following way doesnt seem to work but i dont know why it wouldnt

  

	public void makeEmpty()
        {
            for (int x=0;x<myList.length;x++)
            {
                (Comparable)myList[x]=0;
            }
	}

mylist is defined as an array of comparables

try:

myList[x] = null;

in Java, null & 0 are NOT the same thing.

We need to see some more code. I think I might have an idea but assumption is the mother of all f*&k ups.

well i dont know what else to show you but null just gives me the same error as setting it to zero

it says this

"SortedArrayList.java": Error #: 361 : variable required, but value found at line 124, column 17

  
private Comparable[] myList; // this is how it is initialized
