Is it your homework ?

Trying in google "Lazy initialization", and found:

http://www.javapractices.com/Topic34.cjp

So it's simply idea - don't create object, until someone will get it...
And your code:

private int array[];
public void setArray(){}
public int[] getArray)(){
  if( array == null)
    array = new int[10];
  return array;
}

But I'm sure that it is homework -
some very simple idea, and big name for it.
Why don't you use Google to search ?
