Unit 4: What are all the features of Java Programming Languages? Features Contd....

Features Contd....

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

- Architectural-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 bytecode 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 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.
