What is Java? Why should you learn Java?

Before getting into the technical stuff of Java, let’s start out with the history of this game-changing programming language which is now powering more than 3 billion devices in the world.

Java is a general-purpose object-oriented programming language that is developed by Sun Microsystems. Earlier Java was known as Oak. But after some time it is named as Java.

James Gosling was the lead designer behind the Java programming language. Now it is owned by Oracle Corporation. Java is as known as a programming language as well as a platform because of its JVM (Java Virtual Machine).

The first public release of Java alpha and beta version were announced in 1995. JDK 1.0 released in 1996. Java 1.2 in 1998 and so on. In 2014, Java SE 8 was announced.

The current stable release is Java version 9. Java 9 came up with various bug fixes.


Why should you learn Java?

In today’s era of new emerging technologies, Java still has its reputation maintained in the market. It is the second highest used language in GitHub repositories.

Java is used for the backend development by many of the top companies around the globe. It is also a choice for Android application development by the tech giant Google.

Following are some of the reasons to learn Java:

  1.  Used in web application for server programming such as gmail.com
  2.  Desktop application can be developed like antivirus and games
  3.  You can get into Android app development as well
  4.  Various frameworks like Hadoop and Apache Spark are developed using Java
  5.  Huge number of open source libraries are available
  6.  Huge community support
  7.  Also used for embedded application development and robotics.


What are the features of Java programming language?

Following are the features of Java programming language:

Simple – Java is simple because it does most of the work behind the scenes such as garbage collection so that programmer does not have worry about deallocating the memory. It is based on CPP, so it will better if you have knowledge about CPP.

Object Oriented – Java is a pure object-oriented programming language. Everything is kept in a class. Every object in Java has some data and behaviour. OOP is the methodology that simplifies the development of software.

Portable (Write Once Run Everywhere) – Bytecode is the Java’s magic behind making every program portable on different machines which are having a different platform such as Windows, Mac, and Linux.

Multithreaded – Java allows the programmer to create multiple flows within a single program. In simple words, a single river can be divided into multiple flows. In the same way, multithreading allows a programmer to do multiple tasks concurrently.

Secure – Java programs run inside a Sandbox. Now, what is Sandbox? Well, Sandbox is a memory area where program keeps its data and don’t allow other programs to access it without permission. Hence making it more secure.

Distributed – Programmers can develop such programs which can be executed on different machines to achieve a single goal. RMI and EJB are the concepts used for developing such type of applications.


Why should you learn Java before getting into Android app development?

Android is a Linux based open source operating system which is currently holding approximately 87 percent part of the market. Java is a programming language which is used for developing the Android application. Most of the Core Java concepts will be used while developing an android application.
