 * What is the difference between an Integer and int?
   - `int` is a primitive data type (with `boolean`, `byte`, `char`, `short`, `long`, `float` and `double`), while `Integer` (with `Boolean`, `Byte`, `Character`, `Short`,`Long`, `Float` and `Double`) is a [wrapper](https://docs.oracle.com/javase/tutorial/java/data/numberclasses.html) class that encapsulates primitive data type, while providing useful methods to perform different tasks with it.
 * Do objects get passed by reference or value in Java? Elaborate on that.
-    - In Java all primitives and objects are passed by reference, meaning that their copy will be manipulated in receiving method. But there is a caveat - when you pass an object reference into a method, a *copy of this reference* is made, so it still points to the same object. This means, that any changes that you make to the insides of this object are retained, when the method exits.
