FEATURES OF JAVA

(Tap the post to see more)


1) Simple

Java is easy to learn and its syntax is quite simple, clean, and easy to understand. The confusing and ambiguous concepts of C++ are either left out in Java or they have been re-implemented more cleanly.

Eg: Pointers and Operator Overloading are not there in Java but were an important part of C++.

2) Object Oriented

In Java, everything is an object which has some data and behavior. Java can be easily extended as it is based on the Object Model.

Following are some basic concepts of OOPs.

•        Object

•        Class

•        Inheritance

•        Polymorphism

•        Abstraction

•        Encapsulation

 

3)  Robust

Java makes an effort to eliminate error-prone codes by emphasizing mainly compile-time error checking and runtime checking. The main areas in which Java improved were Memory Management and mishandled Exceptions by introducing automatic Garbage Collectors and Exception Handling.

4) Platform Independent

•         Unlike other programming languages such as C, C++ etc which are compiled into platform-specific machines. Java is guaranteed to be a write-once, run-anywhere language.

•         On compilation Java program is compiled into bytecode or .class file

 •        This bytecode is platform-independent and can be understood by JVM (Java Virtual Machine).

•        The Java Virtual Machine (JVM) is the runtime engine of the Java Platform, which allows Java bytecode to run on any computer that has a native JVM.

Java is a platform for Independent Language

 

5) Secure

When it comes to security, Java is always the first choice. With java secure features it enable us to develop virus free, temper free system. Java program always runs in Java runtime environment with almost null interaction with system OS, hence it is more secure.

6) Multi-Threading

Java multithreading feature makes it possible to write program that can do many tasks simultaneously. Benefit of multithreading is that it utilizes same memory and other resources to execute multiple threads at the same time

7) Architectural Neutral

Compiler generates bytecodes, which have nothing to do with a particular computer architecture, hence a Java program is easy to interpret on any machine.

8) Portable

Java Byte code can be carried to any platform. No implementation-dependent features. Everything related to storage is predefined, for example: the size of primitive data types

9) High Performance

Java is an interpreted language, so it will never be as fast as a compiled language like C or C++. But, Java enables high performance with the use of just-in-time compilers.

10) Distributed

●     Java is also a distributed language.

●     Programs can be designed to run on computer networks.

●      Java has a special class library for communicating using TCP/IP protocols.

●     Creating network connections is very much easy in Java as compared to C/C++.

The most important resource that enterprises must protect is information. In an effort to learn how to secure such vital information resources, the relevant business may incur significant losses in terms of money, brand reputation, customers, etc., if sensitive information ends up in the wrong hands. Various statistics, threat forecasts, key terms related to information security, information security components, and the security, functionality, and usability triangle are covered ...
