Java Tutorial | Learn Java Programming – Digital Namanji


In this article, we had to describe what java programming is, its application, types of its application, their edition, and features of java. So read this article till the end to get basic details about java.

Java is a programming language that is based on class.Java is a programming language that was developed by Sun Microsystems in the year 1995 and the father of java is James Gosling. As its name before this was Oak and that was already a registered company so James Gosling and his team gave the name java From Oak. Java is known as a platform because it runs in a software and hardware environment. 

Edition of java 

4 types of java addition are described below:-

Java Micro Edition (ME)- This is a micro platform that is made for mobile applications.

Java Enterprise Edition (EE)– Java EE is an enterprise platform. It is mainly used for developing web and enterprise applications. Java EE is an enterprise platform.

JavaFX  – It is mainly used for developing rich internet applications. 

Java Standard Edition (SE) – Java SE is a programming language that includes java programming APIs like java. lang, java.sql, java.math,, java.util.

Features of java 

Making a portable, simple, and secure programming language was the primary objective of the java programming languages creation. Here are some Java buzzwords which play an important role in this language. Java has robust, simple, secure, portable, interpreted, architecture-neutral, object-oriented, dynamic, multithreaded, distributed, and high-performance features. All these come under the most important features of the java programming language. 

Let’s describe this one by one- 


It is strong because it uses strong memory management. To get rid of objects Which are not being used by java applications it provides an automatic garbage collection that runs on the java virtual machine. 


the Java programming language is very easy so we can learn it easily.  its syntax is simple because it is based on C++. Java has removed Operator overloading, explicit pointers, and many complicated and rarely used features. It is clean and easy to understand. Java has an automatic garbage collector so there is no need to remove unreferenced objects. 


 Bytecode verifier, Security manager, classloader,  are the securities that are provided by Java programming by default. Java programming runs inside a virtual machine sandbox and has no explicit pointer. Due to the above security features, java is best known for its security. 


It gives us a facility to carry the java code(bytecode) at any platform without any implementation, so it is also a portable language. It provides three types of portability: source code portability, CPU architecture portability, and OS/GUI portability. 

Architecture neutral-

In java, there are no implementation-dependent features so it’s architecture-neutral. 


Everything in java is considered an object so java is based on an object-oriented programming language. Providing some rules java that is object-oriented programming is a methodology that simplifies maintenance and software development.


Java supports the dynamic loading of classes because it is a dynamic Language. Classes are loaded on demand and java also supports functions from native languages, dynamic compilation, and automatic memory management. 


In multithreading, the thread is the smallest processing unit and it is a process in which multiple threads are executed simultaneously. It is mostly used in animation and gaming. 


By using the Hadoop and Spark frameworks, distributed map-reduce programming in java. For creating distributed applications RMI and EJB are used. 

High performance- 

Java bytecode is close to native code so it is faster than other interpreted programming languages. Java is a little bit slower than compiled language because it is an interpreted language. 

Java Frameworks

Java frameworks are the software that is created by themselves to make programming with java. Java has many frameworks. Here are some Java-based common and mostly used frameworks.

Spring –  Besides the default container it doesn’t require a web server and it’s light in weight. Spring java framework makes authentication, validation, and verification processes much easier to include in any project. Spring is a modular project that can be used for any level of the project.  

Hibernate – Hibernate is an ORM (Object Oriented Mapping) based framework. It is open-source and makes common data handling mismatch cases. Hibernate is perfect for OOP-type projects that require high portability and productivity at the same time, with little coding hibernate having the capability for Strong data manipulation. 

Application of Java

A huge amount of devices run java. Here are some examples of devices where java is used are- games, Mobile, smart cards, robotics, embedded systems, desktop applications such as Acrobat reader, media player, antivirus, web application, enterprise application, etc. 

Types of application: 

Web application  

This application runs at the server-side and forms a dynamic page known as a web application.

Mobile application

Mobile application is the application that is created for mobile devices. For example, Android is the application that is currently used for mobile.

Enterprise application

A banking application is an example of an enterprise application. These applications are distributed in nature. It provides a high level of security, load balancing, and clustering. 

Standalone application

Desktop applications and Windows  Based applications come under the standalone application. Media players and antivirus are examples of standalone applications.  

Companies that use java:-

Netflix It provides movies and TV shows on streaming multimedia. It is One of The largest and most popular US entertainment companies.

Spotify It is an online audio streaming service. For implementation, The functionality of its web application java is being used by Spotify.

MinicraftIt is a famous computer game which is written in java.


Java is an object-oriented programming language and it is widely used today for making various web applications and mobile applications. It is used in banking applications too because of its security. Java supports cross-platform. It is also a compiled programming language. But it is also flexible as an interpreted programming language. Java compiles the code and converts it into bytecode. Java has an access modifier for checking memory access.
