Arguments or parameters? [duplicate]

Answer 1

In fact both parameter and argument are different types of parameters. Those are

1)Formal Parameters - variables appear in function/subroutine definitions

for eg. (in Java)

public void foo(Integer integer, String... s2)

Here both integer and s2 are formal parameters or loosely speaking parameters.

2)Actual parameters or arguments - variables appear in subroutines while calling the

already defined subroutine

for eg. (in Java) suppose If the function "foo" resides in object "testObject" ,

testObject.foo(new Integer(1), "test")

So variables in the function definition are called formal parameters or simply parameters and variables while calling methods are called as actual parameters or arguments. I hope it helps.
