Having celebrated its 22 nd anniversary in , Java has experienced consistent development in its programming efficiency for decades. It is one of the most popular programming languages around the world and is designed to keep running on any stage consistently. One of the biggest reasons why Java is so popular is the platform independence. Programs can run on several different types of computer; as long as the computer has a Java Runtime Environment JRE installed, a Java program can run on it.
Most types of computers will be compatible with a JRE including PCs running on Windows, Macintosh computers, Unix or Linux computers, and large mainframe computers, as well as mobile phones. Since it has been around for so long, some of the biggest organisations in the world are built using the language. Many banks, retailers, insurance companies, utilities, and manufacturers all use Java.
Steve Zara, a programmer for more than 40 years, describes how there is no sign of Java declining in use. Instead, it is an evolving language which almost uniquely combines stability with innovation. Highlighting the longevity of the language, Zara states that the code you may have written 15 years ago will run on the most up-to-date JVMs and gain the speed advantage of the latest profiling, native code translating, and memory management.
Java is fundamentally object-oriented. The code is so robust because Java objects contain no references to data external to themselves. Java API, the class library, is as much a part of Java as the language itself. The language consists of 50 keywords, but the Java API has thousands of classes with tens of thousands of methods you can use in your programs. Java is still a relevant programming language that shows no sign of declining in popularity and, for that reason, is worth learning.
Since the language has an English-like syntax with minimum special characters, Java could be learned in a short time span and used to build suitable applications.
Swarnim Srivastava , a Java Enthusiast, agrees that the language is worth learning. He explains the critical areas in which it is used:. Many government, healthcare, insurance, education, and defence departments have their web applications built in Java. Many useful software and development tools are written and developed in Java, e. Once a program has been written, the high-level instructions are translated into numeric codes that computers can understand and execute.
In the early 90s, Java, which originally went by the name Oak and then Green, was created by a team led by James Gosling for Sun Microsystems, a company now owned by Oracle. Java was originally designed for use on digital mobile devices, such as cellphones. However, when Java 1.
However, there have been many updates since version 1. Over the years, Java has evolved as a successful language for use both on and off the internet. Java was designed with a few key principles in mind:. The team at Sun Microsystems was successful in combining these key principles, and Java's popularity can be traced to it being a robust, secure, easy to use, and portable programming language.
To start programming in Java, you first need to download and install the Java development kit. After you have the JDK installed on your computer, there's nothing stopping you from using a basic tutorial to write your first Java program. Here's some more information that should be helpful as you learn more about the basics of Java:. Actively scan device characteristics for identification.
Use precise geolocation data. Select personalised content. Before then, all communication was sent using plain text. JavaScript is a client-side programming language that runs inside a client browser and processes commands on a computer rather than a server.
Despite its name, JavaScript is not related to Java. JavaScript is used primarily in Web development to manipulate various page elements and make them more dynamic, including scrolling abilities, printing the time and date, creating a calendar and other tasks not possible through plain HTML.
It can also be used to create games and APIs. C Language is a structure-oriented, middle-level programming language mostly used to develop low-level applications. C Language is used to develop systems applications that are integrated into operating systems such as Windows, UNIX and Linux, as well as embedded softwares. Applications include graphics packages, word processors, spreadsheets, operating system development, database systems, compilers and assemblers, network drivers and interpreters.
Pronounced C-sharp not C-hashtag , C is a multi-paradigm programming language that features strong typing, imperative, declarative, functional, generic, object-oriented and component-oriented disciplines.
C helps developers create XML web services and Microsoft. NET-connected applications for Windows operating systems and the internet. Objective-C is a simple, general-purpose and object-oriented language. It uses a system of message passing borrowed from the language Smalltalk; when an object in Objective-C is sent a message, it can choose to ignore or forward to another object, rather than return a value. Objective-C was developed at Apple in to address deficiencies specifically lack of object-orientation in C language.
It was licensed by NeXT in PHP is an open-source scripting language designed for creating dynamic web pages that effectively work with databases. It is also used as a general-purpose programming language.
