Java actually passes parameters by value. If you pass an object reference, a local copy of the reference is created but it refers to the same object. So if you want manipulate an object in a method without changing the original, you must make a local copy first by using the clone() method or whatever.

hi!
the only way to pass object to method by call by value is
you need to make a deep clone of the object.This will not affect original one.
