In an instance variable each class object has its own copy of the class's member variables. An object's member variables are separate and distinct from the member variables of the other objects of the same class. A static member variable on the other hand is when a member variable is declared with the key word static.

Primitives are passed by value, i.e. a copy of the primitive itself is passed. Whereas for objects, the copy of the reference is passed, not the object itself. Primitives are independent data types, i.e. there does not exist a hierarchy/super class for them. Whereas every Object is descendent of class "Object".

Object Oriented Programming(OOP) A class is like a blueprint of data member and functions and object is an instance of class. For example, lets say we have a class Car which has data members (variables) such as speed, weight, price and functions such as gearChange(), slowDown(), brake() etc.

A class can have many Constructors but must not have the same parameters. A class can have many methods but must not have the same parameters. A Constructor cannot be inherited by subclasses. A Method can be inherited by subclasses.

Object is a class but it already has(is) an instance, so you can not call new ObjectName . On the other hand, Class is just type and it can be an instance by calling new ClassName() . In scala, there is no static concept. So scala creates a singleton object to provide entry point for your program execution.

Difference between Structs and Classes: Structs are value type whereas Classes are reference type. Structs are stored on the stack whereas Classes are stored on the heap. ... Structs can not have explicit parameterless constructors whereas a class can structs doesn't support inheritance, but classes do.

Functions do specific things, classes are specific things. Classes often have methods, which are functions that are associated with a particular class, and do things associated with the thing that the class is - but if all you want is to do something, a function is all you need.

An instance is a specific representation of an object. An object is a generic thing while an instance is a single object that has been created in memory. Usually an instance will have values assigned to it's properties that differentiates it from other instances of the type of object.
