Introduction to JAVA

The document is a presentation on Java, an object-oriented programming language developed by James Gosling at Sun Microsystems, known for its 'write once, run anywhere' functionality. It outlines various applications of Java, such as in desktop, web, enterprise, mobile, and gaming, and highlights its key features like simplicity, robustness, security, and portability. The presentation also briefly explains object-oriented programming concepts and the process of Java program translation into machine language using the Java Virtual Machine.

PRESENTATION ON PROGRAMMING LANGUAGE JAVA SUBMITTEDBY ParminderSingh 1635499
WHAT IS JAVA?  Java is Object Oriented Programming language as well as Plateform.  Java was developed by James Gosling at Sun Microsystems.  It promised Write Once, Run Anywhere (WORA) functionality.
WHERE IS JAVAUSED ? There are many devices where Java is currently used.  Desktop Applications - Acrobat reader, Media player, Antiviruses etc.  Web Applications - irctc.co.in , javatpoint.com etc.  Enterprise Application – Banking Application, Business Application.  Mobile.  Games
FEATURES OF JAVA • Java is Simple. • Java is Object Oriented. • Java is Architecture Neutral(Fixed). • Java is Robust. • Java is Interpreted and Compiled. • Java is Secure. • Java is Portable. • Java is Multi-Threaded.
JAVAPROGRAM TRANSLATION Hello.java javac Hello.class Interpreter for WinXP Interpreter for Mac Interpreter for Unix Source Program Java Compiler Java Bytecode
JAVA VIRTUAL MACHINE  Java virtual machine is the like usual computer which translate high level language into machine language.  Just like that Java virtual machine also translate Bytecode into machine language.  JVM are available for many hardware and software Plateform.
WHAT IS OBJECT ORIENTED PROGRAMMING Object-oriented programming is a method of implementation. A language in which everything represent in the form of Object is called Object. It makes the program less complex & software reuse feasible and possible. Java is not truly OOP’s Based.
CONCEPTS OF OOP • Object • Class • Encapsulation • Inheritance • Polymorphism • Abstraction
JAVA PROGRAM- DEVELOPMENT PHASES
ADVANTAGESOF JAVA Java is platform-independent.  It follows LIFO (Last in First Out) so data can be stored and retrieved easily.  Java programs can be executed using web.  Write Once Run Anywhere (WORA).
