What is Java?
Java program structure, what is Java in computer
As you may be aware the computer understands not any human
language but a programming language. The programming language is many. One of
them is the Java Programming Language. In this post, we have given information
about Java.
In this post, we will learn what is Java? What is the use of
Java? (What is Java in Hindi), how Java works? History of Java, Types of Java
Applications, Java Version, and applications for writing Java Program.
It is important to have this information about the Java
language used to build Desktop and Mobile applications. In this post, Java has
been told in the first place. With which you will be able to settle very
easily.

What is Java?
Java is a very popular and commonly used General Purpose
Programming Language. Java is a High-Level Programming Language.
Java is used for the development of mobile applications and
desktop applications. Any software developed by programming Java is better and
secure.
To save any file coded from Java Programming Language, .Java
is applied after the file name. That is the extension of Java.
Java's programming code is in English, anyone can read and
understand it very easily. Due to which it is considered High-Level Language.
Java is a programming language that is also based on the
concept of C ++ or Oops. Fundamentals of Oops are used in Java.
Java is a popular programming language that is not designed
for any particular hardware or operating system. A code written by programming
from Java can run on any other platform.
What is the use of Java?
What is Java used for, features of Java
There are many fields where Java is used.
It is used by the programmer to develop programs. If other
programming languages like C, C ++ are compared then it is easier to develop
programs from Java itself.
Java Programming language is used in almost all places due
to Java Security and regular updates in it. Web applications, desktop, and
mobile apps are made using it.
Code is written in Java programming language also runs on
all computers such as Mac Os except Windows.
Below you will now know where Java language is used.
Web application
Web applications are developed using Java.
Java language is also used in some important fields due to
its easy to use and secure. like:-
Java is used in education, in any department of government,
in its alba and other large private institutions.
Desktop application
By this, any type of application of desktop is developed.
For this, various types of application program interface
(API) like Toolkit (AWT), Swing, and JavaFX are used.
Mobile Application
The application is installed and used on mobile. Java is
considered to be a better programming language to develop it.
The Java Micro Edition framework is used to build mobile
applications.
Standalone Application
Standalone Application, which is installed in a computer or
laptop, is also called as desktop applications or Windows applications.
Enterprise Application
Enterprise application is used on a large scale like
Government, Corporate, Business, Schools, etc.
Is more secure and powerful than other languages. Provides
API and Runtime environment for scripting and runtime enterprise software.
Scientific Application
Most developers of developing scientific applications prefer
to do it through Java language.
How does Java work?
How to work Java
Java has more advance and simple features as well as is more
secure in comparison to other programming languages.
For programming with Java language, rules like syntax are
followed.
Java Virtual Machine or Abstract Computing Machine is used
to run its code.
Java Virtual Machine: -
Java Program is run using Java Virtual Machine (JVM).
With Java Java Machine already installed, Java code runs on
every computer.
The code programmed to run on one platform is easily run on
another platform. It does not need to be recompiled again.
Platform Independent: -
Java is called Platform Independent Language because of
running on all operating systems like Windows, Linux, Mac, Android.
There is a difference between platform-independent and
platform dependent.
The reverse happens in the Platform Dependent. Its
programming code cannot be run on every OS.
History of Java
Java History
Java programming language was introduced in the year 1995
by Sun Microsystems developer James Gosling and his team.
James Gosling is considered the main developer of Java.
Whose principle was. "write once run anywhere". That means write once
and run anywhere. Java programming is compatible with all OS platforms.
The Java program was first named greentalk by James Gosling.
It was renamed Oak from Greentalk.
It was renamed again due to being already registered by Oak
Technology. And Java was named.
Types of Java Applications
The Java Programming Language is placed in 3
departments. Whose name is given below?
JAVA 2 Micro or Mobile Edition (J2ME)
JAVA 2 Standard Edition (J2SE)
JAVA 2 Enterprise Edition (J2EE)
J2ME: - JAVA 2 Micro
or Mobile Edition is used to develop mobile applications using the wireless
access protocol.
J2SE: - JAVA 2
Standard Edition is used to develop client-side applications.
J2EE: - JAVA 2
Enterprise Edition is used to develop server-side applications.
It is a Platform Independent Program. With the help of which
Web-Based Enterprise Application can be created.
Java Version History
Java version list, Java version check

version list with the released time is given.

Application to write Java Program
application for Java programming, Java document creation
application
A Java Editor's application is required to write any Java
program.
There are many computer applications available for
programming computer languages such as Java, HTML.
Such as - Notepad ++, Netbeans, Eclipse, etc.
Notepad ++ is a small application that is easy to use. It is
also easy to find the error or Missing Bracket. Which is used by most people?
If you want, you can use any of it.
The more we know about Java, the less is considered. Because
every version of it brings something.
In this post, you got to know “What is Java? What is the use
of Java? (What is Java in Hindi), how Java works? History of Java, types of Java
applications, Java Version, and applications for writing Java programs ”.
