Features of Java

By : Chirantan Mungara

Here is given many feature of java and also java feature also none as Buzzwords all features is given bellow :

1. Simple
2. Object-Oriented
3. Platform independent
4. Secured
5. Robust
6. Architecture neutral
7. Portable
8. Dynamic
9. Interpreted
10. High Performance
11. Multithreaded
12. Distribute

• Simple

  1) Simple means java  Syntax is base on C++ so easy to learn after c++.
  2) and also remove many confusing and/or rarely use feature like explicit pointer and operator overloading.
  3) and also in java no need to remove unreferenced variable because java have Automatic Garbage collector
   

• Object-oriented

  object oriented means we organise our software as a combination of different type of object that is incorporate both data and behaviour.
  
  
  Class
  Object
  Inheritance
  Polimorphisam
  Abstraction
  Encapsulation
   

• Platform Independent

  A platform is the hardware or software environment in which a program runs. There are two types of platforms software-based and hardware-based. Java provides software-based platform. The Java platform differs from most other platforms in the sense that it's a software-based platform that runs on top of other hardware-based platforms.It has two components:    
• Runtime Environment
• API(Application Programming Interface)

Java code can be run on multiple platforms

• Secured

   

   Java is secured because:
  
  
  • No explicit pointer
  • Programs run inside virtual machine sandbox.

   

  Robust

  • Robust simply means strong. Java uses strong memory management. There are lack of pointers that avoids security problem. There is automatic garbage collection in java. There is exception handling and type checking mechanism in java. All these points makes java robust. 
  
  

  Architecture-neutral

  • There is no implementation dependent features e.g. size of primitive types is set. 
  
  

  Portable

  • We may carry the java bytecode to any platform. 

  High-performance

  • Java is faster than traditional interpretation since byte code is "close" to native code still somewhat slower than a compiled language (e.g., C++) 

  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. 

  Multi-threaded

  • A thread is like a separate program, executing concurrently. We can write Java programs that deal with many tasks at once by defining multiple threads. The main advantage of multi-threading is that it shares the same memory. Threads are important for multi-media, Web applications etc.
