Introduction

Avoid being asleep at the switch when hiring Java Developers! Are you a bit taken aback, wondering how it is even possible to be negligent while hiring them? Do you know how you can prevent hiring incompetent Java developers and save your money, time, energy, and effort?

The straightforward answer is to enlighten yourself with the skills and frameworks that a good java developer must know to do justice to your project.

For instance, when you hire Java developers without carefully sieving through the skills of your interviewees, chances are that you end up hiring someone who has faked their proficiency. They may not be able to do justice to their assigned tasks. Such a situation is undesirable for any entrepreneur or an established organization that wants to roll out an app or website needing Java. One deems hiring the wrong Java developers unpleasant as it causes you to waste your money on liabilities. You waste your precious time and end up with buggy software or website.

However, you can keep such a mess at bay by equipping yourself with the right information on how you should go about hiring your Java developers. All it takes is acquiring the right knowledge to segregate the best from the rest!

Who are Java Developers?

We all know Java developers are professionals who use Java Technology to create software, products, and applications. But do you know what Java is?

Java is a programming language based on the syntax of C++ and C and is concurrent, object-oriented, and class-based. Sun Microsystems, now acquired by Oracle, released this programming language in 1995. The basic definitions of Java and Java developers concisely help us understand what these developers do. Let us dive into what their responsibilities look like. 

What do Java Software Developers do?

Hiring Java developers means you must know what skills you need to look for in your candidates. Your ideal Java Software developers must be able to handle the entire development lifecycle of applications well. From the project’s concept and designs to testing them for errors, they must know how to execute these phases keeping in mind the time constraints and the resources at hand. We list their responsibilities below for your reference.

  1. Build app code for Java programs.
  2. Design, implement and maintain various Java app phases.
  3. Come up with technical designs for app development.
  4. Participate in architectural and software development activities.
  5. Suggest changes to improve established java app processes.
  6. Carry out programming, software analysis, testing, and debugging.
  7. Transform requirements into stipulations.
  8. Create, test, implement and handle application software.
  9. Must be able to identify production and non-production app issues.

These are the responsibilities of Java developers, and you, as a recruiter, need to ensure that the ones you want to hire can carry these responsibilities. But the question arises, how will you know what you should look for in your candidates? 

If you ask the same question, you no longer need to rake textbooks to find the solution. Here we list the seven frameworks your Java Developers must know to stand up to your expectations.  

What are the skills you need to look for when hiring Java software developers?

Although your Java developers must know various technologies and possess the right soft skills, a few frameworks exist without which java developers can not ace their jobs.

These frameworks are as follows:

Spring

If you are looking to hire Java developers, you should test their knowledge of the Spring framework. The features of Spring that have made it popular are:

  1. Type-safe configuration
  2. YAML Support
  3. Web development
  4. Spring Application
  5. Properties files
  6. Externalized configuration

  2. Your developers can now test the developed apps along with backward compatibility.
  3. Establishing JDBC connections becomes easier with it.
  4. This framework is compatible with XML Configurations.
  5. Using the Spring framework makes your apps less prone to errors, increasing reliability. Even if bugs arise, their number will be insignificant.

Hibernate

The second framework your Java Developers must know how to use is Hibernate. It can extend Java’s persistence API Support and is an open-source, performance-oriented, lightweight, and Object-Relational-Mapping tool.

When your Java developers use this framework, they simplify the app development with the help of Database interactivity, etc.

The following features make Hibernate popular among Java Developers:

  1. 1. Scalability
  2. 2. Lightweight
  3. 3. Caching
  4. 4. Auto-generation
  5. 5. Hibernate Query Language

Why must you test your java developers’ knowledge on Hibernate?

  1. 1. This framework’s ORM lets communication happen between the app and any database.
  2. 2. It reduces redundancy via JDBC API.
  3. 3. Using the Hibernate framework improves maintainability and productivity.
  4. 4. It is an open-source framework supporting Persistence APIs.

Struts

The third framework your Java developers must be conversant with is Struts. This framework belongs to the Apache Software Foundation. It inherits the Java Servlet API properties, making the entire development process simpler than before.

The reasons for this free and open-source framework being famous are as follows:

  1. Theme and template support
  2. Configurable MVC components
  3. AJAX support
  4. POJO Based Actions
  5. Various result types and tag support
  6. Integration support
