What Is Java Programming Language? Here's the explanation
Many people say that Java is a powerful programming language. This is because it is multiplatform and known to have a complete library.
Therefore, it is not surprising that Java is one of the programming languages that are widely used today.
Curious what Java programming language is like? Come on, see the following explanation from Glints.
The History of Java
In 1991, the Java programming language was first developed through a project called “The Green Project” formed by Sun Microsystems.
With members James Gosling, Patrick Naughton, and Mike Sheridan, the project aims to create a new programming language that is more reliable than C and C++.
After 18 months of work, developer James Gosling developed a new programming language called Oak.
Unfortunately, the name has been registered as a trademark of the Oak Technology company.
Finally, around 1995, Sun Microsystem then officially changed the name Oak to Java which reportedly inspired from Java java coffee/coffee. That is why, the logo of the Java programming language is pictured a cup of coffee.
Understanding Java Programming Language
Java is known to have the motto “Write Once, Run Anywhere”. This shows that any program code written using Java can be directly run on different platforms without the need to reorder.
Why could that be?
Java code writing is usually stored in a java extension file. By using the javac compiler, you can compile a java extension file into a class extension file.
This class extension file is referred to as bytecode and can be run throughout the Java Virtual Machine (JVM).
Judging from its use, as a general programming language you can use Java to create various forms of applications.
This applies ranging from desktop-based applications, websites, mobile, to embedded device applications such as smart devices or microprocessors.
While in practice, Java language does not support procedural programming but uses object-based programming concepts.
Why is Java Used?
Reporting from ThoughtCo, there are several reasons why the Java programming language is used, including:
1. Easy to use
The basis of Java is the C++ programming language. Although the programming language is quite powerful, but classified as context and not enough for various Java needs.
Java was built from and became a kind of improvement from the programming language. This makes Java a powerful and simple programming language to use.
In particular, if you are familiar with C++, you will most likely not have much trouble learning Java.
2. Oriented to object
As mentioned above, it is related to its nature which is an object-oriented programming language. This is different from the C++ programming language which can be considered semi-authorized on objects.
Java has several features of an object-oriented programming language (OOP). These include abstraction, encapsulation, inheritance and polymorphism.
3. Security
Java was originally intended for mobile devices that exchanged data over a network. This makes the Java language built with a high level of security.
Java itself can be said to be one of the programming languages with a high level of security. According to CodeJava, there are no viruses attacking Java applications.
4. Can be used on various platforms
A program can ideally work regardless of what platform it is used to execute it. Java is written as a portable programming language and can be used across platforms.
Use of Java Programming Language
Reporting from w3schools, Java can be used for several things, including:
mobile applications (especially Android)
desktop application
web application
web server and server application
game
database connection
In addition to the above, there are actually many more uses of Java. This indicates that the language is a programming language that is widely used.
Essential Components of Java
Reporting from JournalDev, there are three important components of Java. The three components are:
1. JDJ
The Java Development Kit (JDK) is a core component of Java. It provides all the tools, executables, binaries, and binaries needed to compile, debug, and execute a Java program.
2. JVM
The Java Virtual Machine (JVM) is often considered the heart of the Java programming language. When running a Java program, JVM is responsible for converting byte code into more specific code.
3. JRE
The Java Runtime Environment (JRE) is an implementation of JVM. JVM provides a platform for executing Java programs.
Examples of Java Framework
Talking about the world of computer programming, framework becomes a familiar term. Simply put, a framework can be interpreted as a ready-made programming component and ready to use at any time.
In general, the framework is composed of MVC (Model, View, Controller). Well, in this MVC you can group which are the input functions, processes, and outputs of an application.
If you want to build a website using the Java programming language, the following web framework for Java is often used.
1. The Vaadin Framework
Vaadin Framework has advantages in the form of code used to have similarities with Java SE source code.
If you have previously used Swing, it will not be difficult to adapt to the Vaadin Framework.
2. MVC Spring
First released in 2003, Spring Framework is an open source framework that uses the basis of object-based programming in it.
In addition, this one framework allows programmers to work with technologies and libraries from three different parties.
3. The Java Server Pages (JSP)
JSP is one of the most well-known frameworks for developing web applications. For someone who is used to using Java, it is definitely not going to find any difficulty when using it.
Performance affairs, JSP tends to have good performance because in it has been done compile process to become Java servlet—class that is ready to be run by a web server.
That's a review of what Java programming language is complete with a framework that you can use.
For those of you who want to struggle in the world of programming, then mastering the Java language can be an advantage. If you have mastered it, maybe it is time for you to work in the IT field.
