Java Features
In this section we will discuss about the feature of java, they are as follows.
Simple : Java is a very simple language, syntax is taken from C and C++. so many features are removed like pointer, operator overloading etc. garbage collector is used for object which are not having any reference in memory. so there is a automatic garbage collection in java.
Platform Independent : This is the very important feature of java that make java so popular. Java is a platform independent language so it is called Write Once Run Anywhere(WORA) because output of java code compiler is bytecode that is executed by JVM . Converting a java program into bytecode makes it easier to run on any platform because JVM need to be implemented for each platform.
Secure : Java is secured because it does not provide explicit pointer concept. All program in java are run under Sandbox, security manager determine what resources a class can access for reading and writing to the disk.
High performance : Java is faster than traditional interpretation ,since java uses bytecode that is close to native code.
Distributed : Through RMI and EJB we can create distributed application, we may access file calling methods from any machine.
Multithreaded : Java is a multithreaded programming language. Multithreading means a separate program executing separately. We can write a program that can have many task and it run simultaneously.
Robust : Java is strong language as it support automatic garbage collection, memory allocation and exception handling and also type checking mechanism from as compare to any other programming language.
Object oriented : object oriented mean it will support four feature of OOPs:
- Encapsulation : It is wrapping of data with the method together and using that data and restricting on some object.
- Inheritance : It is mechanism by which one class can acquire the feature of its super class.
- Polymorphism : It means create a function ,variable which have more than one form. so by it one object treated like another object and by this way multilevel inheritance is acheived . It is used foe message passing.
- Dynamic Binding : If a class inheriting super class and have same method , so we don't know which method will compiler called while creating object through dynamic binding means providing maximum functionality to an abject at run-time.
