- 3. JAVA Java is an object Oriented computer programming language which is used to develop desktop and web based applications. It is developed James Gosling in 1991.Oracle Corporation has acquired Sun Microsystem in 2010 . Over the period of time many versions of Java have been released with new enhancements and features.

- 5. OOPS(Object-Oriented Programming System) Object means a real-world entity such as a pen, chair , table , computer , watch , etc . Object Oriented is a methodology to design a program using classes and objects . It simplifies software development and maintenance by providing some concepts like Object , Class , Inheritance , Polymorphism , Abstraction , Encapsulation.
- 7. Object Any entity that has state and behavior is known as an object. Like a chair , pen , table , keyboard , bike , etc. It can be physical or logical . An Object can be defined as an instance of a class. An Object contains an address and takes up some space in memory
- 8. Class Collection of objects is called class. It is logical entity . A class can also be defined as a blueprint from which we can create an individual object. Class doesn’t consume any space.

- 10. Inheritance When one object acquires all the properties and behaviors of a parent object , it is known as inheritance . It provides code reusability . It represents the relationship between Parent and child Types of Inheritance in Java Single level Multi level Hierarchical
- 11. Polymorphism When one task is performed in different ways , it is known as polymorphism .We can perform a polymorphism in java by:- method overloading and method overriding Shape Circle Triangle Rectangle
- 12. Abstraction Abstraction means hiding internal details and showing functionality . In Java, abstraction means simple things like objects, classes, and variables represent more complex underlying code and data .
- 13. Encapsulation Binding (or wrapping) code and data together into a single unit are known as encapsulation . A java class is the example of encapsulation . Java bean is the fully encapsulated class because all the data members are private here. Methods Variables Class
- 14. Advantages of OOPs OOPs makes development and maintenance easier OOPs provides data hiding . OOPs provides the ability to simulate real world event much more effectively . Reuse also enables faster development. It is easy to make minor changes in the data representation or the procedures
