What is Java and How to Learn it for Free

Learn Java Programming – Taking technology to new heights Coding And Computer is a very important role. Such mobile applications are created through coding, which we use in our daily life.

Today we can do online transactions at home with just an application created by coding. We can play games for fun and do many things through the mobile application.

In today’s article, we are going to tell you about Java which is one of the computer programs. In this article, you What is Java and how to learn Java Full information will be available.

In this article, you will learn about the history of Java, its features, and its usage of Java. So let’s start without delay and let’s start this article with an introduction to Java.

What is Java Programming

Java Computer A language is a general purpose language. It is used in many ways to build applications and software.

Java is a high-level programming language. You can run Java on any platform. It supports all operating systems.

The code in Java is written in English so that anyone can understand it easily. In this C++, the basic principle is used.

Java is a widely used computer language, which is simpler and safer than other computer languages.

Java is an oriented computer programming language.

Inventor of Java Programming

Java language was discovered by James Gosling. He first started Java in 1991 as a project called Oak. The first public implementation of Java was Java 1.0 in 1995.

The object of Java Programming

The main goal of the Java programming language was to write once and run everywhere, which means you have to write the language once and then you can use it any way you want. Web Browser can run inside.

History of Java

Java is an oriental programming language. In 1991, a group of engineers at Sun Microsystems, led by James Gosling, decided to develop a programming language for a consumer device.

This project was named Green Project. C++ was then chosen as the first choice, but C++ was not the best language for the project, so a new computer language, Oak, was born.

Java was originally called Oak. It got its name because there was an oak tree outside James Gosling’s office. And the language was named Oak after this tree. Earlier Oak was also known as Green Talk but in 1995 Oak was renamed Java.

The first public implementation of Java was Java 1.0 in 1995. The latest version of Java right now is JavaSE 16.

The Java language is currently owned by Oracle Corporation, according to which Java runs on 3 billion devices worldwide today.

Now we know all the versions of Java that have been released so far. ,

Java version

With the advancement of technology, new versions of Java are released from time to time, following are all versions of Java so far.

Types of Java

By now you must have understood what Java is, now you know how many types it is. Java is mainly divided into three parts.

  • Java Standard Edition
  • Java Enterprise Edition
  • Java Micro Edition

Java Standard Edition (Java 2SE)

Java SE provides us with all the tools to build server applications and desktop applications. All programs are written in Java SE Operating system Let’s go inside.

Java Enterprise Edition (J2EE)

JEE is useful for a web applications, component models, and enterprise-class services.

Java Micro Edition (J2ME)

JME is used in developing a mobile applications, gaming applications, and set-top box software.

Java application types

Four types of applications can be created using Java programming.

Web application

The application that is used to run the server is called a web application. All kinds of web applications can be created with the help of Java.

Standalone application

No browser is required to run this type of application. It can be easily run on any computer.

Standalone applications are desktop and mobile applications that are mostly used. Like Media Player, MS Office, Browser, etc.

Mobile application

Java mobile application is a platform developed for running mobile applications on smartphones. Java is used to create all kinds of mobile applications.

Enterprise application

Java language is used to create enterprise applications such as banking software, accounting applications, etc.

Features of Java Programming

Java A language has many features that make it special, some of the important features are as follows.

  • Safe language – Java is a secure language compared to other computer languages. It protects the application from external attacks.
  • Plain language Java is a simple language whose code is very easy to read, write and compile.
  • Object Oriented Programming Language It is an object-oriented programming language, which means that everything in it is viewed as an object.
  • Architectural Nature – The bytecode generated by the compiler can be run in any operating system, so it is called architectural.
  • Platform independent – Its program can be run on any platform.
  • Portable language Being platform independent, it is a portable language.
  • Multi-threaded With the help of this feature, programs can be written that can perform multiple tasks. This means that multiple tasks can be performed in one application.

Uses of the Java language

The Java language is used for many things. Following are some major uses of the Java language.

  • Java is widely used in creating web applications.
  • Desktop applications can be easily developed with the help of Java.
  • All mobile applications are developed with the help of the Java language.
  • Java is the best language for developing gaming applications.
  • The software can be created with the help of Java.
  • Java is also used to create financial applications.
  • Scientific applications are also created with the help of Java.

Java components

To learn the Java language it is important to know about its components. Only then you will be able to learn Java easily.

Whenever we do any programming it is in human-readable language. This means that humans can understand this coding but machines cannot. Machines can only understand machine language.

So the coding which is done by humans has to be converted into machine language to be understood by machines.

To convert code in the Java language to machine language, three components are important.

Java Development Kit (JDK)

Jdk is a tool package that provides us with the tools we need to program on Create. Jdk is used only by Java developers.

Java Runtime Environment (JRE)

JRE is a set of software used in the development of Java applications. It is a part of JDK itself. JRE provides us with the tools with which the program can be run.

Java Virtual Machine (JVM)

The JVM is a part of the JRE that converts bytecode into machine language. The JVM provides the runtime environment for running Java programs.

How Java Works

Before learning Java it is also important to know how Java works, so let’s know.

When compiling a Java program, first the program is not converted to machine language but to an intermediate language called Java bytecode. This code can be used on any operating system. 

It then interprets the bytecode to execute the program. Java source code is compiled into bytecode by the javac compiler and converted to machine language.

Therefore, a Java program is compiled twice to be executed.
