History of Java

James Gosling initiated Java language project in June 1991 for use in one of his many set-top box projects. The language, initially called ‘Oak’ after an oak tree that stood outside Gosling's office, also went by the name ‘Green’ and ended up later being renamed as Java, from a list of random words.


Sun released the first public implementation as Java 1.0 in 1995. It promised Write Once, Run Anywhere (WORA), providing no-cost run-times on popular platforms.

On 13 November, 2006, Sun released much of Java as free and open source software under the terms of the GNU General Public License (GPL).


On 8 May, 2007, Sun finished the process, making all of Java's core code free and open-source, aside from a small portion of code to which Sun did not hold the copyright.


Java is a high-level programming language originally developed by Sun Microsystems and released in 1995. Java runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. This tutorial gives a complete understanding of Java. This reference will take you through simple and practical approaches while learning Java Programming language.



Why to Learn java Programming?

Java is a MUST for students and working professionals to become a great Software Engineer specially when they are working in Software Development Domain. I will list down some of the key advantages of learning Java Programming:


Object Oriented − In Java, everything is an Object. Java can be easily extended since it is based on the Object model.


Platform Independent − Unlike many other programming languages including C and C++, when Java is compiled, it is not compiled into platform specific machine, rather into platform independent byte code. This byte code is distributed over the web and interpreted by the Virtual Machine (JVM) on whichever platform it is being run on.


Simple − Java is designed to be easy to learn. If you understand the basic concept of OOP Java, it would be easy to master.


Secure − With Java's secure feature it enables to develop virus-free, tamper-free systems. Authentication techniques are based on public-key encryption.


Architecture-neutral − Java compiler generates an architecture-neutral object file format, which makes the compiled code executable on many processors, with the presence of Java runtime system.


Portable − Being architecture-neutral and having no implementation dependent aspects of the specification makes Java portable. Compiler in Java is written in ANSI C with a clean portability boundary, which is a POSIX subset.


Robust − Java makes an effort to eliminate error prone situations by emphasizing mainly on compile time error checking and runtime checking.


First Java Programming (Hello World)

Just to give you a little excitement about Java programming, I'm going to give you a small conventional C Programming Hello World program,



public class MyFirstJavaProgram {


   /* This is my first java program.

    * This will print 'Hello World' as the output

    */


   public static void main(String []args) {

      System.out.println("Hello World"); // prints Hello World

   }

}



Tools You Will Need

For performing the examples discussed in this tutorial, you will need a Pentium 200-MHz computer with a minimum of 64 MB of RAM (128 MB of RAM recommended).


You will also need the following softwares −


Linux 7.1 or Windows xp/7/8 operating system

Java JDK 8


Microsoft Notepad or any other text editor


This tutorial will provide the necessary skills to create GUI, networking, and web applications using Java.

  • .


Popular Java Editors

To write your Java programs, you will need a text editor. There are even more sophisticated IDEs available in the market. But for now, you can consider one of the following −


Notepad − On Windows machine, you can use any simple text editor like light Notepad++ Free  Notepad Download


Netbeans − A Java IDE that is open-source and free which can be free Netbeans download 


Eclipse − A Java IDE developed by the eclipse open-source community and can be downloaded from free Eclipse Download



Applications of Java Programming

The latest release of the Java Standard Edition is Java SE 8. With the advancement of Java and its widespread popularity, multiple configurations were built to suit various types of platforms. For example: J2EE for Enterprise Applications, J2ME for Mobile Applications.


The new J2 versions were renamed as Java SE, Java EE, and Java ME respectively. Java is guaranteed to be Write Once, Run Anywhere.


Multithreaded − With Java's multithreaded feature it is possible to write programs that can perform many tasks simultaneously. This design feature allows the developers to construct interactive applications that can run smoothly.


Interpreted − Java byte code is translated on the fly to native machine instructions and is not stored anywhere. The development process is more rapid and analytical since the linking is an incremental and light-weight process.


High Performance − With the use of Just-In-Time compilers, Java enables high performance.


Distributed − Java is designed for the distributed environment of the internet.


Dynamic − Java is considered to be more dynamic than C or C++ since it is designed to adapt to an evolving environment. Java programs can carry extensive amount of run-time information that can be used to verify and resolve accesses to objects on run-time.

How to become a Java Developer?(Improving Skill Set)

These are the steps to become a successful Java developer –


1. Master Core Java


Begin your Java journey with Core Java and master it. You should have a crystal clear understanding of basic Java concepts like arrays, loops and operators. Moreover, you have to have intermediate knowledge of APIs such as java.io and java.math.


2. Practise till you get it right


Keep practising everything you learn in Core Java so that you can write syntaxes without errors. The best way to understand Java is by executing and implementing code and not by simply learning the theory. 


3. Transition to Java EE


Once you grasp Core Java completely, move on to Java Enterprise Edition or Java EE. This is the advanced version of Java where you can acquire skills needed for web development. Java EE includes technologies such as WebSocket, Servlet and Java Server Faces.


4. Work on projects


Implement your learnings from Java on Front-end languages such as HTML and Javascript to make small projects. This will widen your understanding of Java by helping you comprehend how to use the capabilities of Java to create. Make projects with Servlet and JSP to enhance your skills and knowledge.


5. Learn Spring and Hibernate framework


Once you have a thorough understanding of Java EE, the next step is the transition to Java frameworks, which include Hibernate and Spring Frameworks. Frameworks are prewritten code that you can add to your own code to customised solutions. The two most popular Java frameworks used by companies around the world are Hibernate and Spring. If you are able to develop projects on these frameworks, then your chance of being a successful developer is very high.


How to become successful java development as fresher 


Java is the most popular language used for coding purposes and platforms for practical application. Its popularity can be credited to its multidimensional nature as it can be used to create personalised applications which are fast and light and serve a broad spectrum of purposes.


Java is used in almost every company, whether they are start-ups or tech giants like Amazon, Google, etc. Hence, Java Developer jobs can significantly boost your career in today’s world. 


Java ranks among the top five professional programming languages as per the reports of the 2019 Stack Overflow survey.


Here’s how you can better your chances of getting a Java Developer job:
