About JAVA

Java is an object-oriented computer programming language released by Sun Microsystems IN 1995. Mobile phones to scientific supercomputers, most of the devices employ the usage of Java applications. Java programming derives most of its syntax from C and C++. It is one of the fastest, simplest and reliable platforms as it is one of the most widely used programming languages due to its simplified coding and dynamic functioning.


JAVA Training in PUNE of certification courses are available for various IT professionals who aspire to gain expertise in Java development and programming. Java programming has 50 JVM languages. A complete java training program incorporates practical knowledge and hands-on experience of object-oriented concepts. Apart from this, there are many other topics covered in the course. The course would ask for some prerequisites in the trainee i.e. for instance, as a learner one is expected to have worked on a programming language (C/C++); basic concepts of HTML, database, and SQL syntax etc. The salary and perks offered to a Java developer is an added advantage which in turn add to brighter career scenarios.

How does Java work?

A Java application is compiled to Java bytecode which is the instruction set for Java Virtual Machine (JVM).

Java compiler does not translate Java codes directly to machine code instead it first translates the Java program to BYTECODE which is essentially an object file for a virtual machine that uses the extension.class This byte-code is created for a virtual platform known as the Java Virtual Machine or JVM.

The bytecode verifier in the JVM then checks the bytecode after which the JVM converts the bytecode to a machine-friendly code. To be more specific it is the Just In Time (JIT) compiler of the JVM which is responsible for this conversion. It also keeps the track of the frequently repeated byte-codes so as not to repeat the compilation of same codes again and again.

This is how Java functions. As the JVM converts the bytecode to a machine specific code, therefore we have different JVMs for different Java platforms because JVMs are not platform independent, the platform independence that Java shows is a layer of abstraction, under which dependence on the platform actually exists.

Some advantages of JAVA:
It is an open source programming language, so does not require heavy license fees each year.
It is Platform independent.
Java API's can easily be accessed by the Java developers.
Java always allocates the objects on the stack.
Java embraces the concept of exception and specifications.
Incorporated with multi-platform support language as well as web-services support.
Promotes the development of dynamic web applications.
Java programming allows the creation of modular programs and reusable codes.
Enables secure and high-performance software development.

Java programmers are in demand all over the world. Experienced professionals with Java certification earn higher packages. The job roles one can apply for after completing certification course is that of a Web developer, Software Developer, Application Developer and more. The career prospects in Java Programming are very bright and promise a long term career opportunities by helping them to acquire their dream jobs in the respective field.
