What Are Skills Required for A Java Full Stack Developer?

In today’s digitalized era, software development has become an integral section of technology updates. Various ways within software development include different career options. Some of the career pathways in the software engineering ground stand at the verge, which indicates the career choices are not so simple. JavaScript programming is such a section of software engineering that needs profound knowledge and sharp intellect. If you aim to develop Java-based websites and web applications, you should hire Angular Developers (expert Java full stack Developers) who possess the core knowledge.

The blog will focus on the whereabouts to be Java Full Stack Developers. 

Who is a Java Full Stack Developer?

Full Stack Developer is the one (an engineer) who can work on both the software backend and frontend.

Usually, the term ‘Full Stack’ refers to focusing on the overall potential of a person or a machine like an applicant should have broader knowledge, or an employee must show his/her skills in different job areas, and so on. However, in the case of software development, it depends on the complexity and specification of the project (including other factors) whether the company will hire Full Stack Developers in charge of some specific parts of the software or not. 

For example, a software company may have a devoted Database Developer who can work on the complex database logic, a web designer who can perform a good deal associated with the front end or, a development and operational engineer who will supervise the whole project. Now, all of these developers work on the specific parts individually, which is the entire work arena of the Full Stack Developer. In that case, the company does not need to hire Full Stack Developers.

A Full Stack Developer does not get the chance to work on both the frontend and backend with a 50-50 ratio in bigger software companies. Often, the developer is given the responsibility to work on either the front end or backend. If we talk about the Java Full Stack Developers, they mostly get exposure to the Java backend. 

Resources To Become a Java Full Stack Developer

  • CodeGym

CodeGym is one of the most influential and upgraded online training platforms that will help you to learn Java in detail. Java is the base of online training. If you are interested, you can begin with the introductory courses to know the fundamental core concepts about Java, followed by database and advanced chapters of your choice. 

You can also get into the learning process in a fun way. Here, you will get the opportunity to create your customized versions of the most popular games, like Snake. In addition, this online platform will allow you to access a broader fellow students’ community. 

  • Kotlin for Java Developers 

One of the most effective ways to learn a technology is to listen to the creator. Kotlin is a modern programming language compatible with Java. Kotlin is often referred to be the official language for Android application development. Now, the language also helps in the backend development. If you are familiar with Kotlin, your job search options will get broader automatically. Complete knowledge of Kotlin will boost your experience the most if you work on the current stack projects with young, new teams.

  • Java Fundamentals by Pluralsight

The Pluralsight offers a quality set of courses for different levels to the students. You can start as a beginner and proceed to the advanced levels. Classes for advanced developers are also available, but the number is limited. This platform will offer you essential learning and support from expert developers. The important, crucial topics are covered in detail for the beginner and intermediate levels. The final result reflects in your application development only. 

Backend (Java) Skills

Core Java and Java Ecosystem

You must learn coding to become a software engineer. If you choose to proceed with Java, you have to acquire the basic Java skills and concepts. The topics of variables and literals, arrays and collections, loops and if-else clauses, exceptions, classes, and interfaces, multithreading basics come under the basic knowledge. You may read a classic book or have online training on it.

In this process, you need to delve deep into the Java ecosystem as well. Java cannot work without Java Virtual Machine (JVM) and Java Runtime Environment (JRE). Therefore, it would be beneficial for you to learn the terms early and get a brief knowledge about JVM and JRE. Companies prefer to hire full stack developers with complete understanding.

You need to practice your skills constantly. You may think of hypothetical problems and try to solve them using Java. 

Know How to Store Your Data

Various ways are available to store data. The implementation of applications becomes restricted without data persistence. 

Using a database and keeping your information in files are different. A database comes with the technology that allows you to arrange your data and provides access and data manipulation facilities like searching, sorting, filtering, querying, etc. The difference between database and database management systems is huge. In practice, you can think of two major databases, SQL and No SQL.

SQL is the most important for Java developers for its popularity in corporate and enterprise applications. There are rare giant whales on the scene as Oracle and SQL Server. You will know about relational and non-relational databases as whether data is arranged based on the relations between data types. Most of the SQL databases are relational, and the rest are not.

In the initial phase, you will learn some SQL language used to interact with the SQL database. You will also learn how to perform the basic CRUD (Create, Read, Update and Delete) operations on your created application. Then, you can take the first step by direct use of the JDBC driver. Gradually, you will learn to use Object Relational Mapping systems (including the software libraries) and work on the data more naturally. These qualities and knowledge ease a company’s decision to hire Full Stack developers and hire Angular Developers. 

What is Your Stack?

After you learn the fundamentals, you need to develop and get into the backend stack of choice. You have to use a specific set of technologies to work further on the project. You cannot only use the basics in the medium and large projects; instead, you need to use technologies, libraries, and frameworks. The software companies look for this specific knowledge before they hire full-stack developers

The two most effective stack options for Java are Java Enterprise Edition and Spring Framework. It is not right to consider these two as interchangeable, as Spring is a set of frameworks, and JavaEE is a set of standards and specifications. Spring Framework may be compatible with Java Enterprise Edition. It is a larger ecosystem to build the backend. At present, Spring Framework is considered to be the most dominating stack. The most significant parts of Spring are,

  • Core Spring Components
  • A Spring Security 
  • Spring Data
  • Spring AOP

On the other hand, Java Enterprise Edition has an application server that provides you with libraries. Then, you need to learn the APIs. Some of the essential APIs are, 

  • EJB (Enterprise JavaBeans)
  • JPA (Java Persistence API)
  • JMS (Java Message Service)

Java Enterprise is comparatively complicated than Spring. This stack is used hugely, but mainly on the old systems. The stack will continue to be a feasible choice for the companies to develop their corporate strategies. 

Frontend Skills 

You do not have to be web design to work on frontends. This will have to work on the User Interface (UI) and User Experience (UX). You may work daily and add some features from time to time. In most cases, you do not have to develop a public-facing frontend. You may have to work on either graphic sketches or HTML templates. 

You can hire a Front-end developer in the team if working for clients. In the case of web-based frontends, there is no way to avoid the use of JavaScript. Directly or indirectly, JavaScript is the primary language used here. You may also learn the basics of Typescript to use the language in specific apps. 

Be Comfortable with the Frontend World

You need to be updated with the current popular frontend framework and libraries to be an excellent Full Stack Developer. The languages you can use are Angular, React, Vue.js, etc. You must know the basics and advanced qualities of these languages and how and where to use them. Angular has been a little backdated; still, the companies hire Angular developers for the Enterprise types applications. 

Automated Testing, Development & Operations 

Here, two testing processes come; Unit testing and Integration Testing. After the testing process is over, the building machine process also comes to the ground. 

You must have profound knowledge of the concepts mentioned below,

  • Software Design and Architecture 
  • Design Patterns 
  • Microservices 


Java Full Stack Developer has a versatile role that attracts open-minded people. It would help if you begin with the basic level and proceed to the advanced stage through a thorough learning process. You need to learn and acquire all the skills and ideas to become a successful full-stack developer. The companies will hire full-stack developers with the highest potential.
