Java is a universal and all-encompassing programming language used to develop cross-platform software (applications) that runs on desktops, mobile devices and servers.
Java is a simple, object-oriented, distributed, interpreted, secure, reliable, architecture-neutral, portable, powerful, multithreaded, and dynamic programming language.
Java has attracted programmers from the beginning because they can run Java programs from a web server. These programs are called applets.
This is the reason why Java is very popular today for developing applications on web servers. These applications process data, perform calculations and generate dynamic web pages.
Many commercial websites are developed with Java in the backend. Applications for Android mobile phones are developed with Java.
Message: A platform is defined as any hardware or software environment in which a program runs. Since Java supports a runtime environment, it is called a platform.
In this section we will discover the history of Java, which is very interesting. In 1990, Sun Microsystems Inc. (US) presented a project to develop software for electronic consumer equipment that can be controlled by remote control.
This project was originally called the Stealth Project, but the name was later changed to Green Project.
In January 1991, Bill Joy, James Gosling, Patrick Naughton, Mike Sheridan and several others met in Aspen, Colorado to discuss the project.
Mike Sheridan has focused his work on business development. Patrick Naughton is going to work on the graphics system.
James Gosling had to find a suitable programming language for the project. He thought the C and C++ programming languages could be used to develop this project.
However, the problem he faced in using these languages was that C and C++ were system-dependent programming languages. Therefore, they cannot be used in different computer systems or electronic devices.
So he began to develop a new programming language that was completely platform independent and could run on any electronic device.
This programming language was originally called Oak, but was replaced by Java in 1995.
Java, for example, was developed in 1991 by James Gosling, Patrick Naughton, Chris Worth, Ed Frank and Mike Sheridan at Sun Microsystems. It took 18 months to develop the first working version of Java.
Why the name Java?
James Gosling and his team members drank a lot of tea while developing the Java programming language. They felt that they had developed a better programming language because they had drunk high quality tea.
For example, tea also played a role in the development of the Java language. Therefore, the name of the language has been retained as Java. Because Java was such a unique name, most team members decided to choose that name.
Java, the island in Indonesia where the first coffee was produced, was called Java coffee. The name Java was chosen by James Gosling while drinking coffee in front of his desk during the development of the Java language. The symbol of Java is therefore a teacup.
Java Line: C and C++
As you know, the modern era of programming started with the language C, then C++ and finally Java. C and C++ are the most important computer programming languages ever invented and still widely used.
Java inherits its syntax from the C language. Many object-oriented features of Java are influenced by C++. When Java was created, many programmers were familiar with the C/C++ syntax.
As a result, Java used a syntax similar to that of C/C++, so C/C++ programmers could learn Java relatively easily.
C, C++, and Java provide the general and conceptual framework of a professional programmer, so programmers don’t have major problems switching from one language to another.
Although both C++ and Java support object-oriented programming. But Java is not an extended version of C++. It’s not just an internet version of C++. It is not compatible with C++, either in the bottom-up or top-down direction.
Besides, Java wasn’t really meant to replace C++. Java was designed and developed to solve a specific set of problems that arose during the project.
There are many functions developed in C++ to perform a different set of tasks. C++ and Java will coexist for years to come.
Connecting C# with Java
C# was developed by Microsoft to support the .NET framework. This is closely related to Java. For example, both define the same general syntax, support distributed programming, and use the same object model.
Of course, there are many differences between Java and C#, but in general these languages are very similar.
How has Java affected the Internet?
The Internet has played an important role in promoting Java programming. Java, in turn, has also had a profound influence on the Internet.
First, the development of Java technology has simplified web programming in general and acted as a catalyst that has attracted many programmers to the web.
Second, Java introduced a new type of networking program called an applet that changed the way the world thinks online.
Last but not least, Java also solved some of the Internet’s most difficult problems: Portability and safety. Let’s take a quick look at these issues.
1. Applets :
At the time of the emergence of Java, the applet was one of the most widely available functions. An applet is a special kind of small Java program designed to be sent over the Internet.
It is automatically executed by a browser that supports Java. When the user clicks on a link that contains an applet, it is automatically downloaded and executed in the browser.
Applets are typically used to display data provided by a server, process user input, or perform simple functions, for example. B. provide a credit calculator. They also allow some functions to be transferred from the server to the client.
The creation of an applet has changed the way the Web is programmed by expanding the universe of objects that can move freely in cyberspace.
In the early days of Java, applets were an integral part of programming in Java. But over time they have become less important. Finally, applet support has been completely removed with JDK 11.
As we know, we take a risk when we download a program, because the downloaded code may contain a virus, a Trojan horse or any other malicious code.
For example, a virus program can collect personal information such as credit card numbers, account balances, and passwords by scanning the contents of a computer’s local file system.
Java technology makes it possible to download and run programs safely on the client computer. Java provides this protection (security) by restricting the applet application to the Java runtime environment and denying access to other parts of the computer.
3. Portability :
This is one of the most important aspects of the Internet, as there are different types of computers and operating systems that are connected to the Internet.
With Java, the program can be run on almost any computer with an Internet connection, and it will show the same result. Java has made the Internet inherently portable.
So far, several versions of Java have been released. They are as follows:
1. JDK Alpha and Beta (1995): JDK Alpha and Beta were the first versions in 1995, but their APIs and ABIs are very unstable.
2. JDK 1.0 (January 23, 1996): JDK 1.0 was the first stable version of Java. His code name was Oak. The first stable version of the JDK was JDK 1.0.2, which was called Java 1.
3. JDK 1.1 (19 February 1997)
4. J2SE 1.2 (8 December 1998)
5. J2SE 1.3 (8 May 2000)
6. J2SE 1.4 (6 February 2002)
7. J2SE 5.0 (30 September 2004)
8. Java SE 6 (December 11, 2006)
9. Java SE 7 (July 28, 2011)
10. Java SE 8 (March 18, 2014)
11. Java SE 9 (September 21, 2017)
12. Java SE 10 (March 20, 2018).

frequently asked questions
What is the development of Java?
The Java programming language was originally developed by Sun Microsystems. It was launched by James Gosling and released in 1995 as a core component of Sun Microsystems’ Java platform (Java 1.0 [J2SE]). … The new versions of J2 have been renamed Java SE, Java EE and Java ME respectively.
How did Java come to be?
Java was developed at Sun Microsystems, Inc. where James Gosling led a team of researchers to develop a new language that would allow electronic devices to communicate with each other. Work on the language began in 1991, and the team’s attention soon turned to a new niche: the World Wide Web.
What explains Java?
Java is a programming language and computer platform developed by Sun Microsystems in 1995. There are many applications and websites that will not work if Java is not installed on your computer, and more are added every day. Java is fast, safe and reliable.
