Call-by-value:

  1. Copy the value of an argument into the formal parameter.
  2. Change made to the parameter have no effect on the argument used in the call .

Call-by-reference.

  1. A reference to an argument is passed to the parameter.
  2. Change made to the parameter will affect the argument used to call the subroutine.

When you pass a value type, such as int or double, to a method, it is passed by value.

An object is passed by reference
