a class describes the contents of the objects that belong to it : it describes an aggregate of data fields (called instance variables), and defines the operations (called methods). object: an object is an element (or instance) of a class; objects have the behaviors of their class.

There are four different type of classes available in c#. A class with static keyword that contains only static members is defined as static class. A static class cannot be instantiated.13 Kas 2018

Read moreWhat is EQ class in Haskell?
The Eq class defines equality ( == ) and inequality ( /= ) . All the basic datatypes exported by the Prelude are instances of Eq , and Eq may be derived for any datatype whose constituents are also instances of Eq . The Haskell Report defines no laws for Eq .
Read moreWhat is type of a class?
In computer science, a type class is a type system construct that supports ad hoc polymorphism . This is achieved by adding constraints to type variables in parametrically polymorphic types.
Read moreWhat is an instance of a Haskell type class?
An instance of a class is an individual object which belongs to that class . In Haskell, the class system is (roughly speaking) a way to group similar types. (This is the reason we call them “type classes”). An instance of a class is an individual type which belongs to that class.
Read moreWhat is a class constraint Haskell?
Everything before the => symbol is called a class constraint. We can read the previous type declaration like this: the equality function takes any two values that are of the same type and returns a Bool. The type of those two values must be a member of the Eq class (this was the class constraint).
