Introduction of Java:• Java Platform is a collection of programs that help
programmers to develop and run Java programming
applications efficiently.
• James Gosling developed the Java platform at Sun
Microsystems, and the Oracle Corporation later acquired it.
• Java is pure object oriented programming language
(Not 100 %)
1. Java class does not support multiple inheritance
2. Java still use primitive data types
3. Static keyword is used in java so that no need to create
object
• There are four types in Java
Class
Interface
Enumiration
Annotation
Features of Java :• Great Performance
• Inspired by c and C++
• Multi-threaded
• Platform Independence
• Truly Object-oriented
• Secure and Simple
Oop’s concept :• Oop’s means object Oriented Programming concept.
• Oop’s concept is used in various programming
language
• There are four major pillers in this concept
1. Inheritance
2. Abstraction
3. Polymorphism
4. Encapsulation
Oop’s concept :Inheritance :•
The relation between parent class and child class is called as
Inheritance.
•
The purpose of inheritance is code reusability.
•
We use ‘extend’ keyword for inheritance in java.
Polymorphism :-
•
Polymorphism means one name many form.
•
we achieve polymorphism through “overloading” and “Overriding”.
•
The purpose of Polymorphism is to make readability and
understanding easy.
Oop’s concept :Abstraction :• Abstraction is process of hiding implementation details and showing
only functionality to the user.
• We achieve abstraction by using “interface” and “abstract class”.
• Interface :• It is a bunch of rules, guidelines and specifications.
• In interface all methods are ended with semicolon(;).
Abstract class :• Abstract class means partial class.
• We achieve security using abstraction.
Oop’s concept :Encapsulation :Grouping of data members and methods are called as
encapsulation.
We can achieve encapsulation by making data members as private.
Setter and getter method is best example of Encapsulation.
