Roadmap for Java developer – 2021

Roadmap for Java Developer

You might find unspecific and odd answers to the question on online forums regarding how long it takes to be a Java developer. However, it entirely depends on the learning dimensions of a person. But, usually, it takes almost three months to twelve months for an individual to learn Java.

The core aim of this roadmap is to assist you in identifying what to find out next instead of encouraging you to choose what’s in trend. Here you’ll find a list of technologies, libraries, and tools that you have to accustom to be a Java developer.

1. Skillset for Core Java Development

As a Java beginner, commence learning the core Java development. Here are the capabilities required you to progressively work on Core Java development and website development company:

Core Java

Core Java is truly the base for all the Java EE technologies and frameworks and so be sure that you simply have a decent foundation in the core java segment.


Data Structures and Algorithms

Data Structures and Algorithms are the basic building blocks of any programming language.
As a programmer, you ought to have an affable understanding of data structures and algorithms.

Java Testing

Check out the Mokito and JUnit framework for unit testing in Java. As a Java programmer, you ought to have good knowledge of testing your core logic utilizing the JUnit framework.

Knowledge on Databases

As a core Java developer, you must have basic knowledge of databases. Here are some mostly used No SQL databases and relational databases:

       No SQL Databases:

• CouchDB

• MongoDB

• Elastic Search

     RDBMS:

• MySQL

• MS-SQL server

• PostgreSQL

• Oracle

Design Patterns

In software engineering, a design pattern is the usual repeatable solution to a generally occurring problem in software design. It’s an outline or template for how to unravel an issue that could be utilized in various different situations.

Desktop Application Development

Within the Java community, you’ve JavaFX and Swing to develop desktop-based applications. Swing and JavaFX are such legacy libraries that can be utilized to build desktop applications.

2. Skillset for Java EE development

Once you’re conversant in Core Java development, then learn the below skills to figure on Java EE development to work at a website development company:

Servlets and JSP

Servlets and JSP are utilized to develop web applications.

JPA

The Java Persistence API (JPA) is a standard for mapping out Java objects to a relational database. Mapping Java objects to database tables is known as Object-relational mapping (ORM).

JAX-WS

Java API for the XML Web Services (JAX-WS) is a standardized API for making and consuming Simple Object Access Protocol (SOAP) web services.

JAX-RS

JAX-RS is actually Java API for the RESTful Web Services (JAX-RS). It’s a Java programming language API spec that gives support in making web services.


Microservices

Spring Cloud and Spring Boot are the super combination to develop Microservices in Java. Spring Boot is currently a leading trend and broadly utilized Java framework for constructing MicroServices. Spring Cloud is truly an implementation of varied design patterns to be followed while making Cloud Native applications.


Spring Framework

Spring framework makes Java EE development much easier. Spring framework is definitely a must-learn skill for Java EE developers. The Spring Framework is a Java platform that gives inclusive infrastructure support for advancing Java applications. Spring handles the Java infrastructure so that application developers can immensely focus on your application.

Hibernate Framework

As a Java EE programmer, you have to learn the Hibernate framework to develop DAO layer. Hibernate is truly a java based ORM tool that gives a framework for mapping out the application domain objects to the relational database tables and the other way round.

Spring Boot

Spring Boot is actually an extension of the Spring framework which mitigated the boilerplate configurations needed for fixing a Spring application.

Top Required Skillset To Be a Java Developer in 2021

1. SQL

With the assistance of SQL, it becomes quite easier to troubleshoot backend issues. SQL supports the API for processing and accessing data that are stored within the database for Java.

2. Git & Github

Both Git and Github proffer irreplaceable version-control functionality to the developer, which helps in the incessant development of the project.

3. Data Structures & Algorithms

Programmers utilize data structures to organize and store data. On the opposite hand, algorithms are employed by programmers to control data inside data structures.

4. Linux

Linux is a broadly used OS for databases, servers, applications, and websites. It makes the Linux command line tremendously imperative for developers.

5. HTTP/HTTPS

For a developer, it’s essential to understand the difference between HTTP and HTTPS, different HTTP methods, how they work, which one is safer, and the objective of both.

Finally, yet importantly, one thing that you have to ensure is learning incessantly. On average, you have to be learning Java for around 1-3 hours routinely. You can’t learn by just reading the books or from a website development company in Kolkata. Programming is unquestionably a practical activity. To become a skillful programmer of Java, commence practicing code as earlier as possible.
