| polymorphism :best example is human .we perform different activities at different places in home we are a doughter or son at school we are a student outside we are a citizen . Abstraction: when we have an idea about an start up we just tell the idea but not about the implementation details similarly in java abstraction we are just telling functionality nut not the code. inheritance: in company there is s project with 1000 lines of code and the first 500 are generated by an employee and he left the office after that the work is given to other employee so the other employee extends the properties done by previous employee to reduce his time in working over 1000 lines again. | 0 |

| OOPS Concept With Real Life Example Objects: Object is the basic unit of object-oriented programming.Objects are identified by its unique name. An object represents a particular instance of a class. There can be more than one instance of an object. Each instance of an object can hold its own relevant data. An Object is a collection of data members and associated member functions also known as methods. Classes: Classes are data types based on which objects are created.Objects with similar properties and methods are grouped together to form a Class. Thus a Class represent a set of individual objects. Characteristics of an object are represented in a class as Properties. The actions that can be performed by objects becomes functions of the class and is referred to as Methods. Example #1: For example consider we have a Class of Cars under which Santro Xing, Alto and WagonR represents individual objects. In this context each Car Object will have its own, Model,Year of Manufacture, Colour, Top Speed, Engine Power etc.,which form Properties of the Car class and the associated actions i.e., object functions like Start, Move, Stop form the Methods of Car class. No memory is allocated when a class is created. Memory is allocated only when an object is created, i.e., when an instance of a class is created. | 0 |
