Slide2

Introduction of java

Java is a general-purpose computer programming Language.

It is a subset of C and C++.

Developed James Gosling in Sun Microsystems Labs USA in 1995.

Java, initially called Oak after an oak tree that stood outside

Gosling's office.Slide3

Where it is used?

Desktop Applications such as media player, antivirus etc.

Web Applications such as irctc.co.in, javatpoint.com etc.

Enterprise Applications such as banking applications.

Mobile

Embedded System

Smart Card

Robotics

Games etc.Slide4

Types of Java Applications

Standalone Application

It is also known as desktop application such as media player, antivirus etc

Web Application

It is also known as dynamic page that runs on the server side

Enterprise Application

An application that is distributed in nature, such as banking applications etc.

Mobile Application

An application that is created for mobile devices. Like currently Android and Java ME Slide5

Features of Java

Simple

Platform independent

Secured

Robust

Portable

Reliable

High Performance

Architectural NeutralSlide6

Object-Oriented :Its features are:

Object

Any entity that has state and

behavior

is known as an object. For example: chair, pen, table, keyboard, bike etcSlide7

Class

Collection of objects is called class. It is a logical entity.Slide8

Combining data(variabl

) and functions(methods) into a single unit called

class

and the process is known as

Encapsulation

.

DATA ABSTRACTION AND ENCAPSULATION:Slide9

Encapsulation

It binds together the data and functions that manipulate the data, and that keeps both safe from outside interference and misuse.Slide10

Inheritance

It is a mechanism in which one object acquires all the properties and

behaviors

of parent object.Slide11

Types of inheritance

Single Inheritance

Multilevel Inheritance

Multiple Inheritance

Hybrid Inheritance

Hierarchical InheritanceSlide12

Polymorphism

Polymorphism is the ability of an object to take on many forms.Slide13

Types of Polymorphism

Compile Time

Run TimeSlide14
