In Java it is ALWAYS pass by VALUE. Confusion occurs because all OBJECT variables in Java are references to objects. When we call a method in Java the object reference is PASSED BY VALUE to the method (this means that a variable for the method's argument is created and the reference is COPIED to it).

@Bill:Pass by value of objects references is called pass by reference. In java its always pass by references unless we are dealing with primitives which is pass by value.

If a object is reassigned to a new refernces the original reference is not lost
