Introduction of Java:
Java is a high-level programming language recently developed, concurrent, class-based, object-oriented programming and run-time environment. Java is originally developed by Sun Micro-systems and released in 1995. Java runs on a variety of platforms such as Windows, Mac OS and the various versions of UNIX. This blog gives a complete understanding of Java. In June 1991 James Gosling initiated Java language project for use of his many set top box projects. Sun released Java 1.0 in 1995 “the first public implementation”.
Features Of Java:
There is given many features of java. The Java Features given below are:
1. Compiled and Interpreter : Java has compiled and interpreter feature program and java is first compiled and then it is must to Interpret it. First of all the program of java is compiled then after compilation it creates bytes codes rather than machine language.
2. Platform Independent : A program or technology is said to be platform independent if and only if which can run on all available operating systems with respect to its development and compilation. (Platform represents O.S).
3. Simple and familiar : Java programming language is designed to be easy and understand to learn. If you understand the basic concept of OOPs Java, it would be easy to master.
4. Robust : Robust means reliability. Java makes an effort to eliminate error level situations by emphasizing mainly on compile time error checking and run time checking.
5. Object-Oriented : This allows you to create modular maintainable applications and reusable code.
6. Distributed : We can create distributed applications in java. RMI and EJB are used for creating distributed applications. We may access files by calling the methods from any machine on the internet.
7. Multi-threaded and Interactive : Java uses Multithreaded Techniques For Execution Means Like in other in Structure Languages Code is Divided into the Small Parts Like These Code of java is divided into the Smaller parts those are Executed by java in Sequence and Timing Manner this is Called as Multi-threaded.
8. Dynamic and Extensible Code : Java has Dynamic and Extensible Code Means With the Help of OOPS java Provides Inheritance and With the Help of Inheritance we Reuse the Code that is Pre-defined and Also uses all the built in Functions of java and Classes.
9. Secure : Java was designed with security in mind. As Java is intended to be used in networked/distributor environments so it implements several security mechanisms to protect you against malicious code that might try to invade your file system.
10. High performance : Java programs are complied to portable intermediate form know as byte codes, rather than to native machine level instructions and JVM executes Java byte code on. Any machine on which it is installed.
Version of Java :
The version of java programming are:
2. Java version JDK 1.0 was released in 1996
3. Java version JDK 1.1 was released in 1997.
4. Java version J2SE1.2 was released in 1998.
5. Java version J2SE1.3 was released in 2000.
6. Java version J2SE 1.4 was released in 2002.
7. Java version J2SE 5.0 was released in 2004.
8. Java version Java SE 6 was released in 2006.
9. Java version Java SE 7 was released in 2011.
10. Java version Java SE 8 was released in 2014.
ADVANTAGES OF JAVA:
1. Simplicity : Java is easy to learn.Java programming provides a very easy interface between the users and developers. Java has been considered as the simplest language when compared to other programming languages.
2. Portability and Platform Independent Behavior : Java is platform of independent. Java has been provides to “Write Once and Run Anywhere”facility.The Java applications are supported by every Java. The applications developed by using java language can be run on any software and hardware platform.
3. Allocation : Java has the feature of “Good deal” allocation system. Java helps the data to be stored and can be restored easily.This management system makes it easy to store and restore any object. Java has automatic garbage collection and memory allocation facility.
4. Execution : Java is relatively slower and takes more memory space than the other native programming languages like C and C++.
5. Single Inflection Language : Java is actually predominantly a single inflection language but in the newer versions of Java like Java 5.0 and on wards, the proceeding inflection is made batter by adding some static imports in it.
SCOPE OF JAVA:
Java is everywhere on all platforms and devices and in all countries around the world. It enables developers to make programs work just about anywhere. And it inspired the evolution of an incredible technology community. The brilliance of Java is the platform Independence. Thanks to the internet and the community spirit around it, so many people have been able to make a difference, earn a place in the spotlight with their own framework or tool, be recognized for their contribution, and really influence the Java world.
In today’s competitive business world, organizations are struggling to stand first and get more benefits. In India, Information technology is the one, which has held the first position for long years with many innovative trends. It has multiple stream and platforms to develop an application or product. When we talk of programming languages and technologies, Java is the most popular platform, which is used to develop several applications for the systems as well as embedded devices like mobile, laptops, tablets and many more. It is an object oriented programming language and has a simple object model, as it has derived from C and C++. It provides a virtual machine, which is accumulated with byte-code and can run on any system .
