Understanding Java Development
Due to the broad and capable nature of the Java language, experience can come from any number of areas of interest. Understanding these, and the unique skills required to create a functional team, is key to knowing what you require to move your firm forward.
An experienced Java developer, for example, would be expected to have in-depth knowledge and understanding of modern versions of the language and its latest features. They would be expected to bring a high-level understanding of the project architecture and potentially come with specialist skills such as web services, enterprise beans, or Android development experience.
To understand the ecosystem of Java development and the skills necessary to navigate it, our article on the top Java development skills in demand right now takes a look at precisely these challenges. From tracking the latest language releases to practicing the latest skills and knowledge required to remain up to date, knowing the most in-demand skills can keep you ahead of the curve.
For developers with less experience in the language, the knowledge requirements should be slightly less focused and more broadly applied. Hiring managers should instead look for practice in some of the common libraries used for production and testing, API experience, and some degree of familiarity with common frameworks and tools as a reasonable baseline.
Some common technologies developers should be familiar with in Java development include:
- The JVM (Java Virtual Machine) that runs all Java-written code in a virtual environment on any hardware
- JVM Components and subsystems including ClassLoader Subsystem, Runtime Data Area, Execution Engine
- Garbage collection. Used to retrieve unused objects from memory and create space
- Multithreading, parallelization, and thread synchronization. Key performance tools in developing Java
One of the more modern trends of Java development is a shift toward microservice architectures. Consisting of independent modular services, these can be used to deploy major applications in an efficient way that can be easily modified, upgraded, and maintained by developers. Our article on Microservice trends in Java analyses the technologies that are making microservices popular amongst teams and what they will mean for organizations in the future.
Whether deploying microservices, mobile apps, or a cloud platform—it’s the core skills in Java that will define application success. Taking a broader look at these essential skills, and how they impact services, tips to be a better Java developer takes a close look at understanding Java and listing the things necessary to make up your teams.
