Skills for Java Developers
Very few people know that Java developers are widely known for the skills they own. Consequently, it is of utmost importance to bear in mind whether they own the desired skill set or not. Otherwise, there is no point in hiring java developers.
Let’s have an insight into the required top skills for Java Developers and make it easy for businesses to hire the best Java Developers for their projects.
Java Fundamentals
The basics are always important. The fundamentals of Java mean the basic skills one needs to have as a java developer. It is the basic knowledge only which brings to light whether you have a clear understanding of the basics or not.
The fundamentals of Java include Object-oriented programming concepts, interface, and serialization. It is object-oriented programming that serves as the guiding principle of programming in Java.
Next comes the java interface. The Java interface contains constants, static methods, default methods, and nested types. Having these basic skills makes the operations go smoothly with the software development.
Serialization occurs when the project is converted into bytes. All these three skills are a must-have for java developers.
Web technologies
Another crucial skill for java developers is the knowledge of web technologies. It is the understanding and knowledge of web technologies that assist java developers to build rich, engaging, and dynamic applications.
Be it front-end, back-end, or full-stack, possessing these skills on the part of java developers is important. Some of the crucial web technological skills required by java developers are:
HTML- It is the programming language and forms the basis of the web application. This forms the basis of the starting point of the web developer.
CSS- The next most important technological skill required on the part of the web developer is CSS. It governs the elements of the HTML and allows the developers to manipulate the design so that web content remains organized.
Javascript- It is a logic-based programming language for creating and modifying web content so that all its elements can interact with each other.
JSP- Java Server technology pages technology is effective in creating dynamic web applications which remain independent of the server and the platform.
Java web frameworks
The next crucial skill required for Java Developers is proficiency in java web frameworks. The frameworks refer to the tools with a pre-written code acting as a template. The developers are free to re-use the framework and make the desired changes to make new applications and that too without working from scratch.
Consequently, when hiring a java developer for your organization in 2022, it is imperative to do a knowledge check of the candidate and decide. The candidate must be well conversant with some of the popular frameworks which include spring, Hibernate, Google Web Toolkit, struts, and play.
The java developer having all these skills will face no trouble in developing the solutions and that too in minimum time.
Design and architecture
Be it software, webpage, or any other thing, system design, and architecture form the basis of all applications. The java developers need the working knowledge of design patterns so that they can devise appropriate solutions. The design patterns include the following:
- Creational pattern designs
- Structural pattern designs
- Behavioral pattern designs
- Miscellaneous design patterns
It is not only about having theoretical knowledge of these designs but also practical knowledge. The practical knowledge will only make you capable of implementing these designs into the architecture.
DevOps Tools
DevOps has played a groundbreaking role in streamlining software development irrespective of the programming language employed by the business. It is the DevOps tools only that infuse java development with the principles of continuous integration and continuous development.
While hiring the java developer for the next project, make sure the following DevOps skills are presented to him:
Docker- This DevOps tool is used to build, and execute distributed applications on multiple systems.
Jenkins- Jenkins tool is widely known for monitoring the execution of recurring tasks which in turn will make room for continuous integration.
Apache ANT- It is a command line tool for automating the software build processes.
Chef- The next best DevOps tool is the chef which is used for incorporating the speed and consistency in infrastructure during the project development.
Ansible- It is a tool used in automating application deployment, cloud provisioning, and many more such things. The java developers can make the most out of this tool by boosting their productivity.
The java developer adept in using these advanced DevOps tools can bring long-term value to your business and project.
Database management
The next crucial skill required for the java developer is database management. Not many businesses and companies realize that database management is a key component for maintaining a high volume of data.
The java developers are expected to understand the nuances of database development and management. Figure out if the java developer has these advanced skills present in him or not and decide accordingly. The advanced skills of a java developer include:
Oracle- It is a widely known database management tool and is readily available for the use of businesses.
SQL- It is a standard language used for storing, manipulating, and retrieving data in database management.
Tableau- It helps to visualize the data and extract business intelligence from it.
Apache camel- It allows the java developers to integrate systems for producing or consuming data.
Apache Hadoop- It assists with the database management and processing of big data. Some of its crucial components include Hive, Pig, HDFS, Hbase, and many more to go.
Testing Tools
Is your java developer acquainted with the top tools and their functionalities or not? The java developers should be familiar with how to write a code and also test its performance later on irrespective of the language they are using.
The testing tools which are highly significant for java developers include Selenium, TestNG, and Mockito. With the help of these testing tools, java developers can easily evaluate the functionality of the java application no matter what size it is.
It will also eliminate the worry of hiring a separate candidate for testing purposes. Consequently, do ask the developer about his testing skills and make out if he’ll be the best fit for your project or not.
Soft Skills
In addition to all the technical skills, the java developer should also possess soft skills. Usually, the java developer’s skills are only technical but the java developer should also have soft skills.
By soft skills, we mean communication, teamwork, time management, and creativity. As java developers have to work with people from different walks of life, they need strong communication skills to convey the meaning.
The teamwork allows the java developers to work within or outside the organization. Likewise, a java developer has to make efficient use of one’s time to fulfill the deadlines. It is these soft skills that determine if the java developer is the right fit for your organization or not.
