***In Java, primitives and object references are passed by
value.***
The variable represents the bit information which is copied
to the parameter.
eg:primitive****
Say for primitives x=2, the value of 2 is represented in
bits and it is copied to the parameter variable.
eg:object reference***
Button b = new Button("hello");
Button c = b;
Similarly for object reference the bit value in the
reference is copied to the parameter reference. Thus both
references have the same value representing an object. The
object reference(bit representation) represents a way to
get to the object.
