I want to the syntex in Java that passes arguments by reference and by value.

um.
Pointers dont exist in java so passing by reference might be troublesome in the sense you might be meaning.

passing by value is easy

Say you have a function, "Blah" for instance and you want to pass it a string by value

You would have the function like so :

CODE

public void Blah(String newvalue)
{
//newvalue contains the passed value
}

To pass something to it you would call it like

CODE

String randomstring = "asdfghjkl";
Blah(randomstring);

Et voila

i think java actually passes to methods as a reference?

I assume that you want to pass a parameter to a method which modifies the parameter's value. There's a good discussion of this at the following web site:

This is generally only needed when you need to return more than one value. Otherwise, make the method return type the object that is created/modified by the method.

Everything is passed by reference in Java. Except primitives.

Note that String objects aren't passed by reference but copied instead.
