Java is the most widely used programming language in developing client-server applications, web-based applications, desktop applications, mobile applications etc. There are several benefits of learning java language. 1. Platform Independent First and foremost benefit of learning Java is that it is platform independent, means a java program written in one computer can be run in any other computer without recompiling it because java compiler does not convert source code of java directly into machine code, rather it first converts it into bytecode, which is then converted by Java virtual machine (JVM) into machine code. So, that generated bytecode can be run in any computer regardless of environments, and this is also called portability (WORA) means write once run anywhere. 2.  Easy To Learn Java language is very easy to learn for professionals and also for beginners because its syntax is inherited from C and C++, so those who know basic of one of these languages can easily...

Importance Of Object-Oriented Programming (OOP) What is OOP? What are the benefits of using OOP language? How it is used in any language? There are a number of programming paradigms used in programming like imperative programming, declarative programming, structured programming, functional programming, procedural programming etc. OOP is the most widely used programming paradigm nowadays which defines the concept of classes and objects. The class is the template or form of the object, just like the map is the architecture of the house. It defines the blueprint of data representations and methods for manipulating and using that data, and an object is the real entity of the program which works exactly as defined in the class, as the house will be constructed exactly same as defined in map. Programming Paradigms OOP defines the features like Inheritance, Polymorphism, and Encapsulation which are used to simplify code and reduce the complexity of the programs when they become l...

Java Programming Language Java is a high-level language developed by James Gosling and others at sun microsystems (a company which has since been acquired by Oracle Corporation in 2010) in 1992 to resolve the problems of portability means a program written on one machine can be run or execute on other machines without recompiling it. This is achieved by converting source code into bytecode then in machine code. Java compiler converts the source code into bytecode, then java virtual machine converts that bytecode into machine code. So that bytecode can be run on every computer where there is JVM exists regardless of any environment and we don't need to recompile the program. The second aspect of developing java was networking because internet also requires portability means one website should be run on any computer. Java consists of several versions like J2SE (Java 2 Stand-Alone Edition) used to develop desktop applications and applets (the special type of programs which ru...
