Introduction To Java

Java is a very popular programming language. It is an open-source technology for developing platform-independent applications.

Depiction of the Need for Java using a Real-Time Scenario:-

Arya - Hey, Suhani I love playing the CRISS CROSS Game on my mobile. I am not able to install that game on my mobile.......... Can you please help me out?

Suhani - Sorry Arya. It can be installed on Android mobiles only. Yours is iOS. So you are not able to install it.

Arya - It would be great if games are developed such that, they can run on any mobile, irrespective of the underlying OS,

Suhani - Yes, For that, they should have used technology like Java.

History of Java

James Gosling initiated the development of Java at Sun Micro Systems in June 1991. Finally, Sun released the first public implementation as Java 1.0 in 1995. Java runs on various platforms, like Windows, macOS, Unix, etc.,

Because of its various features which are more advantageous than other languages, Java is one of the fastest growing and the most widely used programming languages of all time.

What is Java?

Java is a high-level, class-based, simple, secure, platform Independent, and object-oriented programming language. It mainly focuses highly on data and is followed by the behaviors that affect this particular data thereby changing the state of the corresponding object from one form to the other form.

Features of Java

Object Oriented Programming Language
Platform Independence
Architecture Na or J2EE) - Used to develop complex applications for large organizations. It focuses more on server-based applications that can be used by multiple users at a time.
Java Micro Edition (JME or J2ME) - Used for developing mobile applications and also for applications on embedded devices.

Java Platform

Java platform is the name given to a computing platform from Oracle that helps programmers to develop and run an application. Java was originally developed by Sun and later acquired by Oracle in 2010.

The Java Platform consists of two essential software -

Java Development Kit (JDK)
Java Virtual Machine (JVM)
