Not everything is about technical knowledge.
DEV article examples include software design and architecture, DevOps containers and tools, Spring framework, unit testing, application program interfaces (APIs), libraries, Java Virtual Machine (JVM) internals, design patterns, Kotlin, microservices and integrated development environments (IDEs). .
The fact that Java is so widely used means that many resources are available for people who want to learn it. Engineers can learn Java in a university Bachelor of Arts or Master's degree program in Computer Science, Computer Engineering, or other related fields. They can also learn from online programs or be self-taught. Once trained, Java engineers can choose to acquire additional certifications, such as those offered by Oracle.
Employers typically look for formal education as well as practical experience. Some hiring managers may waive the degree requirement for candidates with extensive practical experience.
Developers trained in Java can use it to build a wide variety of software products including those mentioned above, as well as financial trading applications, Java 2 Platform Micro Edition (J2ME) applications, big data technologies, and scientific applications.
Quality mindset
In addition to technical skill, Java developers must demonstrate a high level of professionalism, including attention to quality. High quality is important for all stakeholders, including contracting companies, customers and end users, as products that do not meet quality standards can disappoint end users and negatively impact companies' reputation and bottom line. Furthermore, the higher the quality of developers' work, the more opportunities they will have to use their skills.
High-quality applications work well and perform all their functions reliably. Security is another big component of code quality. The code must be easy for other coders to understand and must be thoroughly tested and repaired if necessary. Quality-oriented engineers use testing and other methods throughout the development process to ensure a high-quality final product.
Problem solving skills
Excellent Java development engineers are great problem solvers. These professionals use a logical and methodical approach to overcome challenges that occur during development. They see obstacles as part of the process and, in fact, welcome these trials as “puzzles” to be solved.
An engineer with great problem-solving skills can spend hours looking for the right solution to move your project forward. Developers can use some of these specific problem-solving skills:
- Fully describe the problem, why it is a problem, and the end goal
- Break the problem into smaller “chunks” and deal with them separately
- Using a whiteboard or other means to solve the problem visually
- Think logically about the problem before trying to change the code
- Developing a plan to update the code
The following video describes some of these methods in more detail:
Openness to new ideas
Java developers must be willing to learn from a variety of sources, including formal education, mentors, online community members, or their own creative ideas. These engineers must also keep up with the latest developments in technology in general, as well as the industries in which they typically work. For example, developers who work primarily for financial companies must be aware of the trends, needs, and demands of financial companies' customers.
Developers will also get new ideas and feedback on projects from teammates. Working alone with coding is a big part of being a Java engineer, but these professionals must also collaborate with others to turn that code into a fully functional program or application.
Communication is a big part of teamwork, and engineers must also be able to productively exchange ideas with customers, testers, and end users. For example, developers must gather requirements at the beginning of each project to understand exactly what the requestor wants.
The right combination
Java developers can help businesses, organizations, and other entities achieve their goals, such as increasing productivity, interacting with customers, and increasing revenue. To do this, they must acquire technical knowledge about Java and coding in general, as well as complementary skills such as problem solving and teamwork. Engineers who can bring all of these talents together are better positioned to face any challenges their employers or clients may present.
