Passing by Value (Object References).

In an earlier video, I discussed a common difficulty that every beginner Java programmer encounters - does Java pass primitive data variables (i.e. int, float, char, boolean, etc) to method parameters by value or by reference. Recall Java always passes by value (passes a copy) and never by reference (passes the original).

In this video, I explain using examples how Java passes object references by value (that is to say - passes a copy of the object variables, arrays, etc) . In particular, I illustrate in detail how the passing by value of object references can exhibit behavior that is very similar to passing by reference (i.e. passing the original object memory address).

I hope you find this video beneficial. Please leave any comments or feedback in the comments section and I will respond as soon as I can. Thank you.
