Java argument passing
How many ways can an argument be passed to a subroutine and explain them?View Answers
October 25, 2010 at 4:41 PM
Hi,
Here is the answer.
An argument can be passed in two ways. They are passing by value and passing by reference.
Passing by value: This method copies the value of an argument into the formal parameter of the subroutine.
Passing by reference: In this method, a reference to an argument (not the value of the argument) is passed to the parameter.
Thanks.
