Skill Sets to Look For in a Java Developer

Java developers are skilled in a variety of skills. They are able to work with different languages and frameworks. Java developers have an array of skills that they need to master. These skills will depend on the type of company they are working for and the kind of projects they are working on. Some Java developers might need to know how to use a specific framework or language, while others will be expected to know how to create user interfaces or work with databases. Some of the most important skills include design patterns, database design, and queries, concurrency, and multi-threading, performance tuning, debugging, unit testing, and refactoring.

• Proficiency

  The developer must have strong proficiency in the latest Java concepts and the ecosystem surrounding it. Java8 is currently the widely used programming language; look out for that.

• OOPs

  Since Java is an object-oriented programming language, look for developers who are well-versed in OOPs concepts.

• Frontend

  Although Java is a backend programming language, developers must also be proficient with frontend skills to build enjoyable user experiences. A full-stack Java developer is an ideal option.

• ReactJS

  Expertise in ReactJS is crucial as it simplifies frontend development for developers. It enables developers to describe user interfaces declaratively, removing most of the legwork from the coding activity and making the code easier to read and understand.

• Database integration

  All Java developers must be proficient in data storage, processing, retrieval, migration to different databases, and have basic knowledge of how to link databases with the application.

• Core-Java

  It is a part of the Java language which can be used to develop general-purpose applications. An ideal Java developer candidate must be proficient in Core Java.

• DevOps

  To ensure continuous integration and deployment, Java developers must have DevOps expertise. Developers must understand programming best practices, how to set up an infrastructure environment, write scripts, and follow rules.

• Git

  Git is a vital tool for Java developers; every Java developer should master it. See if the developer has worked on projects in Git; it can be used as an added advantage.

Most Popular Java Frameworks

Sun Microsystems first made Java available in 1995 as a programming language and computing platform. Java is the second most popular programming language in the world, after JavaScript. There are many Java frameworks available, and it can be difficult to choose which ones to explore. Some of the most popular Java frameworks include Spring Boot, Dropwizard, and SparkJava. The list of Java frameworks below comprises some of the most popular frameworks that Java developers use to build their applications.

• Spring

  Spring Framework is one of the most widely used, high-quality, sleek software application frameworks designed for Java software design, development, and deployment.

• Hibernate

  Hibernate is among the most effective Frameworks for augmenting Java's Persistence API support. It is an open-source ORM (Object-Relational-Mapping) technology that is exceptionally robust.

• Struts

  Apache Struts is a dynamic open-source web application framework. It adheres to the MVC (Model-View-Controller) model and improves the JSP API to accelerate the development process.

• Wicket

  Jonathan Locke created Apache Wicket, a component-based application development framework. Wicket is a simple Java web framework with a component-oriented structure.

• Dropwizard

  Dropwizard is a lightweight and simple Java Framework that allows developers to create Java web applications easily. Dropwizard is used for creating friendly RESTful web applications.

• Play

  Play is an open-source web application framework based on the MVC architecture. Since Play is compiled to Java bytecode, it is one of the most powerful frameworks.

• Vaadin

  Vaadin is the open-source flagship of the Java Framework. It employs HTML 5 and provides the tools required for web application development.

Questions to Ask When Hiring Java Developers

1. What are the various access specifiers for Java classes?

ava’s Access Modifiers are designed to specify the accessibility to or the scope of a field, class, method, or constructor. Java developers can change the access levels as required by implementing the access modifier. There are four types of access modifiers or visibility specifiers for Java classes: default, public, private, and protected. A Private Modifier gives access only within the class, while the Default Modifier provides access only within the package. The Protected Modifier uses child class to protect the class both within and outside the package. Last, but not least, the Public Modifier provides access within and outside the class, and also within and outside the package.

2. What are the benefits of using Spring?

If you are hiring a Java developer, it is important to have a list of questions ready. This will help you screen candidates and make sure that they are the right fit for your company. Design your questions in a manner that you can acquire more information and understanding about their experience with Java, experience with web applications, open-source contributions on GitHub, experience with JVM, experience as a team lead or project manager, proficiency with big data technologies, and more.

• Simple Testing & Non-Invasive

  Testing an application end-to-end with Spring is easy owing to the dependency injection system. Also, Spring eliminates the need for developers to inherit specific classes or applications/implementations/executions on any UI.

• Fast & Well Organized

  The Dependency Injection functionality in Spring makes framework integration easier and faster while also providing robust support to JavaEE-based apps. Spring also comes with an MVC Web Framework that helps Java developers build apps using Struts and the like.

• Suitable API & Lightweight

  As compared to EJB containers, Spring is significantly lightweight. The light nature of Spring helps Java developers develop and deploy apps even on computers that restrict memory & CPU resources. Spring has the capability to translate anomalies in tech into consistent but uncontrolled exceptions.

3. Does Java have a static class?

Yes, Java has static classes. Java supports Static Methods, Static Classes, Static Instance Variables, and Static Block. The nested class is defined in the Outer Class while the Inner Classes can be both static and non-static. You can create a static nested class without having to create its outer class. Also, a static class has access to only the static members from the outer class, but the inner class has access to both static and non-static members of the outer class.

4. What is the Java Classloader?

Java ClassLoader is an object which is used to load Java classes to JVM. It basically refers to an abstract class from java.lang package that loads classes from multiple resources and helps load classes at runtime. Your developers will load the classes into the JVM as per application-specific requirements. Java Classloader typically works with three principles, i.e., Delegation Principle, Uniqueness Principle, and Visibility Principle. The types of Java Classloader would include Boostrap Class Loader, System Class Loader, and Extensions Class Loader.

5. How can you connect a Java application to a database?

Java Developers can connect a Java application to a database in a few simple steps

• Register the Driver class
• Establish a connection
• Create a statement
• Run queries
• Close the connection
