Features of Java
Features of Java
java features:
- Features of Java
- Simple
- Object-Oriented
- Platform Independent
- secured
- Robust
- Architecture Neutral
- Portable
- High Performance
- Distributed
- Multi-threaded
There is given many features of java. They are also known as java buzzwords. The Java Features given below are simple and easy to understand.
- Simple
- Object-Oriented
- Platform independent
- Secured
- Robust
- Architecture neutral
- Portable
- Dynamic
- Interpreted
- High Performance
- Multithreaded
- Distributed
Simple
| According to Sun, Java language is simple because: |
| syntax is based on C++ (so easier for programmers to learn it after C++). |
| removed many confusing and/or rarely-used features e.g., explicit pointers, operator overloading etc. |
| No need to remove unreferenced objects because there is Automatic Garbage Collection in java. |
Object-oriented
| Object-oriented means we organize our software as a combination of different types of objects that incorporates both data and behaviour. |
| Object-oriented programming(OOPs) is a methodology that simplify software development and maintenance by providing some rules. |
| Basic concepts of OOPs are: |
|
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:
|
Secured
| Java is secured because: |
|
|
| These security are provided by java language. Some security can also be provided by application developer through SSL,JAAS,cryptography etc. |
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.
