Features of java

Java is now one of the most popular programming language. Its success can be traced by its programming features and designs. The “write one run anywhere” is one of the most important feature.

Some of the features of java are as follows,

1. Object Oriented
2. Platform Independent
3. Distributed
4. Robust
5. Secure
6. Multithreaded
7. High Performance

Object Oriented

Java is a purely object oriented language. Every variable, constant or function is a part of an object. An object or a class is always needed to access its member variables or member functions.

Platform Independent

It is one of the main feature of java. Java is platform independent at source code level i.e. at bytecode level. Java bytecode can be moved from one platform to another platform without any difficulty. Java is a strongly typed language, we have to declare type for every variable. The data types in java are consistent across all platforms. The java interpreter read the bytecode and converts it into the native language of the machine.

Distributed

Using java we can create applications than can run on different platform, GUI and operating system. Java is designed to make distributed computing easy and efficient. Java also provides various libraries for creating network based applications.

Robust

Java is a designed to create highly reliable and robust applications. It checks errors in code during compilation as well as at the time of interpretation. This eliminates various programming errors. Java does not have pointers and pointer arithmetic. In java programmer does not need to bother about memory deallocation as this task is done by garbage collection very effectively.

Secure

Java implements a good security mechanism to protect the system from viruses in code. It assumes that “no code is safe” for execution.

Multithreaded

Multithreading is now a very essential for software applications. Applications have to carry various tasks at a given time. Java provides a very easy mechanism to develop multithreaded applications that are capable to perform various tasks simultaneously.

High performance

Performance plays a very important role in software. It is always believed that execution of bytecode is not as fast as a complied language. But as the processors are advancing this become a myth. Java bytecode executes nearly as good as C or C++
