What is JAVA

Java, the programming language. It was introduce by Sun Microsystems. This work was initiate by James Gosling and the final version of Java was release in the year 1995. Download JAVA click here

However, initially Java was release as a component of the core Sun Microsystem platform for Java called J2SE or Java 1.0.

The latest release of Java or J2SE is Java Standard Version 6. The rising popularity of Java, as a programming platform and language has led to the development of several tools and configurations, which are made keeping Java in mind.

For instance, the J2ME and J2EE are two such configurations. The latest versions of Java are called Java SE and Java EE or Java ME instead of J2SE, J2EE and J2ME.

The biggest advantage of using the Java platform is the fact that it allows you to run your code at any machine. So, you just need to write your code once and expect it to run everywhere.

JAVA is :

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.

 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.

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.
