Class is a key word to create an User defined data type. Every language have data type like int,float etc, but we can’t do all the work by these data types so we need some data type for user requirement that’s why we are creating class.

Class is template of object. EX - suppose we have a car & there are different type of accessories in car. like breaks, gear, CD player, etc all are the object & combination of it is called class.

It is a logical representation of a physical object(entity).
Example:
Class Fruit {
string name; string shape; string odour; double price; -- ---
}

public static void Main() {
Fruit Apple=new Fruit();
}

Here Fruit is a class (general representation ) and Apple is physical.

Encapsulation :- It is a process of wrapping or binding state(variables) and behavior(methods) in a single container.
  Posted by Gautam Kushwaha. (Feb 13, 2014)
 

polymorphism: one thing in different form. like as let us take a function area().

we use this area function in different form in same class like.
area(rock);
area(rock,socks);
area(rock,socks,takes); etc. means different uses of one function.

Encapsulation: Writing Operations and methods stored in a single class. This is Called Encapsulation Real Time Example:

Medical Capsuals i.e one drug is stored in buttom layer and another drug is stored in Upper layer these two layers are combined in single capsual.
