Features Of Java

 

o   Simple

    Java is a simple language, due to the following reasons.

                        1. Garbage collection.

                        2. Provides huge predefined code

                        3. Documentation.

                        4. User Friendly Syntax.

o   Platform Independent

    Developing and compiling the code on one operating system, if the same compiled code is successfully running on other operating system is called Platform Independent.

o   High Performance

    other programming languages use only one translators to  

    Application performance is depends upon the following things.

                    1) Less response time

                    2) Less memory utilization

                    3) More end users.

        If we go for other languages, they are using only one translator for executing the program so those languages will take more time to execute. If any application take more time to execute then that application performance will be decreased.

        To avoid this problem java internally uses two translators

                1. Interpreter.

                2. JIT Compiler

            Compiler: 

It is a translator. It will convert our source code to byte code. It checks all lines at a time.

Interpreter 

It  translate from byte code to machine understandable code. It will check line by line.

JIT Compiler

              Jit compiler mainly used for increasing the speed of interpreter.

o   Security

    Java provides huge security in the following ways.

                1) Avoiding the pointers.

                2) Security Packages

                3) Byte code verifier

               

o   Architectural Neutral

   Developing and compiling the code under one processor, if the same compiled code is successfully running on different processor is called Architectural Neutral.

o   Portable

  The combination of both Platform in-dependency and Architectural Neutral is called portable. 

o   Robust

    Java is a robust language due to the following reasons.

                     1) Proper Memory Management.

                     2) Exception Handling.

                     3) Casting.

o   Multithreaded

      Java is multithreaded language as it allows us to execute multiple task at a time. Executing multiple threads simultaneously is called multithreading.

o   Distributed    

Distributed applications (distributed apps) are applications or software that run on multiple computers within a network at the same time and can be stored on servers or cloud computing platforms.

o   Dynamic

Java is considered dynamic because of Bytecode. The source code which is written in one platform that code can be executed in any platform. It loads the class file during runtime only. Hence, any thing that happens in runtime is dynamic.

o   Oops

    Java is purely oop due to following reasons

        class , object, abstraction, Inheritance , Polymorphism , Encapsulation
