Java Features and its importance

Java Features(Importance)

The main aim of Java programming language generation and Java Features was to make it portable that means it can be easily carried. It is simple and secured programming language. A part from this, there are also some important Java Features which play most important role in the popularity of this Java Programming language. The Following are the list of most important features in Java programming. The Java Features are simple and secured and also easy to understand. The features or Characteristics of Java are also known as Java Buzzwords. Mainly there are 12 Java Features (Java Buzz words). They are:

Java Features1. Simple
2. Object-Oriented
3. Portable
4. Platform independent
5. Secured
6. Robust
7. Architecture-neutral
8. Dynamic
9. Interpreted
10. High Performance
11. Multithreaded
12. Distributed

Java Features1. Simple(Java Features)

Java is easy to learn. If you learn the basic concepts of Object Oriented Programming through Java, it would be easy to be master or expert in Java. Java is easy to understand and the syntax are very clear to understand.

2. Object-Oriented

Java is Object-oriented programming language. Every existing thing in Java is an object. Object-oriented means to organize the software as a combination of different types that consolidates both data and behaviour of an objects. It can be easily extended since it is depended on the Object model.

3. Portable

Java is portable because it makes easy you to carry the java bytecode into any platform. It is easily carried and movable so, Java is said to be Portable. In Java compiler it is written in ANSI C with a clean portability or flexibility boundary, that is a POSIX subset. Being architecture-neutral and having no implementation or execution dependent forms or conditions of the specification or blueprints makes Java portable.

4. Platform independent

Disparate many other like C and C++. When Java is compiled, it is not compiled into platform specific machine or platform dependent machine, rather into platform independent and divided into byte code. This byte code is distributed and interpreted by the Java Virtual Machine (JVM) on every platform it is being run on.

5. Secured

With Java’s secure feature it enables to create virus-free, damage-free systems.  Java is familiar with its security and its Flexibility.

6. Robust

Java makes an struggle to assassinate the error collapsed situations by indicating mainly on compile time error and runtime error checkings. Robust means strong and Java is robust because Java has Strong memory management and automatic garbage collection.

7. Architecture-neutral

Java is architecture neutral because it has no implementation dependent features for example size of primitive data types is fixed.

8. Dynamic

Java is designed to be more dynamic than C or C++ since it is considered to adjust to an deriving or growing environment. Java programs or records can carry comprehensive amount of run-time instructions that can be used to authenticate and resolve approaches to objects on run-time.

9. Interpreted

Java FeaturesJava compiler translates the code or program into bytecode and then the Java Interpreter generates machine code from bytecode that can be executed directly by the machine and that is known as running of Java program.

10. High Performance

The use of Just-In-Time compilers, Java approves high performance.

11. Multithreaded

Java FeaturesIn Java, the multithreaded feature that is possible to write programs and execute the multiple tasks or requests by the same user simultaneously.

12. Distributed

Java is designed to be distributed environment of the internet. RMI(Remote Method Invocation) and EJB(Enterprise JavaBeans) are used for development of distributed applications. Java is distributed because it promotes users to create distributed applications in java.

Introduction for Java and Overview(History of Java- James Gosling)

Introduction for Java

Introduction for Java

Java is Object oriented language because it supports all oops concepts. We cover the topics that the Introduction for Java and History of Java and its basics.

It is a high level programming language and it is not understandable by machine in introduction for java. Java was firstly developed by Sun Microsystems which was initiated by “James Gosling” and java was released in 1995 as core component of the ‘Sun Microsystems’ Java platform (Java 1.0 [J2SE]) and later it is implemented and undertaken by Oracle. And now we are using or latest version of java is Java 8.0 [J2SE]. There are 2 more versions java 9(older version) and java 10(latest version).

There are three latest J2 versions of java they are:
1. J2SE
2. J2EE
3. J2ME

1. J2SE: It is a Java Standard edition. The latest version of Java Standard edition is Java SE 8.It can work on various types of platforms.
2. J2EE: J2EE means Java Enterprise Edition. It is used for enterprise applications. Java EE are increasing day by day.

Introduction for Java
3. J2ME: J2ME means Java Mobile Edition. It is used for the implementation mobile applications.

Java can run anywhere it is a slogan given by Sun Microsystems “Write once, run anywhere”, or sometimes it maybe “write once, run everywhere”. It was a catchphrase said by Sun Microsystems because they want say benefits of Java programming language.

History and Introduction for Java

Introduction for Java

Java was first initiated by James Gosling. James Gosling originated Java project in June 1991 for use of his many set-top box designs and programs. The Java language, firstly called as ‘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 Microsystems released first version of Java in 1995 the version is Java 1.0. Java aasured Write Once, Run Anywhere (WORA), it providing no cost and it runs on popular or various types of platforms.

Sun Microsystems announced Java for free and open source software for everyone under the terms of the GNU General Public License (GPL) in 13th November 2006.

On 8th May 2007, Sun Microsystems finished the process and making of all Java’s core code for free and open-source, seperately from a small segment of code to which Sun did not hold the copyright.

James Gosling is known as the “Father of Java“. At present James Gosling is working as chief technology officer at Sun Microsystems. But now java is under taken by Oracle. Java was the first programming language that was designed with internet in mind and which is used to highly distributed applications. Java is First initiates by James Gosling later it is worked by some others.
