There is a cluster of coding languages to learn but you don’t need to learn all of them, just maintain command on one of them strongly. So many beginners have this same confusion of what language should I choose to better lead my coding carrier.

So the suggestion is to go with Java. Now again the question arises why Java? So in this article, we are going to discuss all java languages and complete a guide to unlocking your java carrier.

What is Java?

Java is an object-oriented and general-purpose programming language. It was developed by James Gosling at Sun Microsystem in 1991. It is used for designing and developing mobile applications, web applications, database connections, etc. It is one of the most popular and widely used programming languages that work on different platforms.

The structure of java allows the users to reuse the code and lower the development cost. The rules and syntax of Java are based on C and C++ language.

Why learn Java?

Here we will see some of the features of the Java programming language to find the reason why to learn Java?

  • Java is easy to learn: It takes very less effort in learning as it has a very simple syntax based on C and C++ languages. The coder can easily learn and understand the concept of java and get started with it very soon.
  • Java has an abundant API: It has a very liberal API (Application Programming Language) which involves classes, packages, interface, etc.  It has three types of API named Official Java core API, Optional Official Java APIs, and Unofficial APIs. These APIs are used for networking, I/O, databases, media, XML parsing, speech, etc. 
  • Java is platform Independent: Since the java code is converted to byte code with the help of a compiler that can be run on any platform. Java can be executed on any platform like windows, LINUX, etc. 
  • Java is versatile: Java is used for programming applications on the web, mobile, desktop, etc., and used on different platforms. It has so various features like dynamic coding, multiple security, platform-independent and network-centric designing, etc.
  • Java is secured: it can develop a virus-free system and is best known for its security because it has no explicit pointer, runs inside a virtual machine sandbox, security manager, byte-code verifiers, etc.
  • Java is robust: java is a very robust programing language as it uses strong memory management and provides automatic garbage collection to get rid of the object which is not used by the java applications anymore. It has also a checking mechanism and exception handling which makes java robust.
  • Java is portable: Java is said to be portable because the coder carries the java byte-code to any other platform and it does not need implementation everywhere.
  • Java is dynamic: Java has dynamic nature as it loads the dynamic classes on-demand, dynamic compilation, memory management, garbage collection, etc.

Types of web development:

Learn Java - types of web development

Before starting your carrier in web development, you should know the various kinds of web development in the IT field. So web development is categorized into three main parts:

  1. Front-end web development: The responsibility of the front-end developer is to make the look of the website interactive and professional including images, colors, icons, etc. This is responsible for the look and feel of the website. The front-end programming languages include HTML, CSS, and Javascript. It is also known as client-side web development. The client-side web development includes the designing procedure of websites based on front-end technologies.
  2. Back-end web development: It is also known as server-side web development. The back-end developers are responsible for the source code and logical part of the website. It includes the coding and algorithm part by focusing on back-end logic, databases, servers, and APIs.This includes the typical programming languages such as JavaScript, PHP, MySQL, etc. The back-end coding joins the website to the server.
  1. Full-Stack web development: Full-stack web development includes both the front-end and back-end responsibilities. Full-stack developers do the back-end coding as well as design the user interfaces. They have the proper knowledge of web designing, database, and website debugging as well. Additionally, the full-stack web developers are continuously in search of new trends like block-chain, deep learning, and multi-cloud based on the projects they are provided.

  • Keep Practising: Practice makes the man perfect. So keep practicing the core java so that at least you should not face any error while writing syntax. Command on theory is good but practical implementation is the most mandatory thing in learning a programming language. You should know the approach and error-solving concepts. So this all comes by practice again and again.
  • Start learning Java EE: After completing the core java part start your advanced java journey. Advanced java enables you to work on web development, web services, servelet, Web-Socket, java server faces, etc. 
  • Start making projects with Servlets and JSP: Try to make small projects based on your concept. After finishing with the advanced java, join it with front-end languages like HTML, CSS, and javascript so that you can make complete projects even for the presentation, mention in the resume, or your accomplishments. You should make at least two projects, one on JSP and the other on Servlet. This will give an analysis of your command of Java Programming.
  • Start learning Hibernate and Spring Framework: Almost all of the big companies are using frameworks such as Spring Boot, Spring MVC, and spring cloud. So after finishing up with both the core and advanced java, you should go with some projects based on the Java framework including the Hibernate Framework and Spring Framework.
