Guide To Java Programming Language
Introduction to Java
Java is a general purpose and the most popular object-oriented programming language. Due to its simplicity and easy to learn features, it is the first choice of programmers today. The Java programming language is related to C and C++ but it is organized rather differently, with many sources of bugs and complex features of C and C++ omitted and as few ideas from other languages included. In addition to the object-oriented features, it also provides features such as platform independence, security, multithreading, portability, etc. The Java platform has benefits for the end user as well as developers and support personnel.
Java is conventional languages which are generally designed either to be compiled to machine code or to interpreted from source code at run time, Java applications are intended to be compiled to bytecode that can run on any Java Virtual Machine (JVM) regardless of the computer architecture.
History of Java
The idea of Java was conceived in January 1991 by James Gosling, Mike Sheridan, Patrick Naughton and several other individuals who met in Aspen, Colorado to discuss the Stealth Project funded by Sun Microsystems. This project was started due to the profound impact of microprocessors. The goal of this project was to control microprocessors embedded in consumer-electronic devices.
Gosling was convinced that C++ was inappropriate for this project. So, he decided to create his own simplified computer language that would avoid all the problems he had Oak. Thus, resulted in a new language known as ‘Oak’ named after an Oak tree outside the gosling office window. The first implementation of Oak was in the PDA type device that released in September 1992. After that, Sun formally announced Java at major conference Sun World in 1995.
Features of Java
- Object-Oriented: Java is a fully object-oriented language because programming in Java is centered on creating objects, manipulating objects and making objects work together. In Java, everything is an object.
- Simple: Java is a compact and simple language.
- Secured: Java was designed with security in mind.
- Platform Independent: Unlike many other programming languages including C and C++, when Java is compiled, it is not compiled into platform specific machine, rather into platform-independent byte code.
- Robust: Java is designed for writing programs that are highly robust. By robust, we mean reliable. Java provides strong type checking feature and eliminates error prone programming constructs such as pointers.
- Portable: The portability actually comes from architecture-neutrality. In Java, the size of the primitive data types are machine independent. It has been simplified.
- Architecture Neutral: One of the key features of Java that makes it different from other programming languages is architectural neutral. This means that the programs written on one platform can run on any other platform without having to rewrite one recompile them.
- Dynamic: Java is designed to be dynamic. In Java, a program can dynamically extend itself by loading the classes it needs to expand its functionality. Also new code can be added to the libraries without affecting the application that are using the libraries.
- Interpreted: Unlike most of the programming languages which are either compiled or interpreted, Java is both compiled and interpreted. These two steps allow extensive code checking and improved security.
- High Performance: Java programs are faster than program or scripts written in purely interpreted languages but slower than C and C++ programs that compiled to native machine languages.
- Multithreaded: Java is also a multithreaded programming language. It allows you to write a program that can do many tasks simultaneously. This feature makes Java most suited for the interactive, GUI based networked environment where idle time is common.
- Distributed: Java is a distributed language which means that the programs can be designed to run on computer networks.

Java is an object-oriented programming language. It is a general-purpose programming language, mainly designed to run developed java code on all platforms that support Java without recompilation.
As we all know, Java is one of the most popular and in-demand programming languages to learn and it was one of the first languages to standardize high-level threading utilities.
