Objects are passed by reference. If you need to pass a numeric variable by reference then you can create a single element array.

Thanks Erel, now I remember reading about that before.

You specified that a numeric variable can be done with an array - I assume that string and other primitives can also be done with the array approach?

Strings are objects so they are passed by reference. However strings are immutable. If you want to modify the string then you should use StringBuilder.

Primitives = Numeric variables, booleans and chars.
