Java is a widely-known programming language that was invented in 1995 and is owned by Oracle. It is a server-side language that was created to let app developers "write once, run anywhere". It is easy and simple to learn and use and is powerful, fast, and secure. This object-oriented programming language lets the code be reused that automatically lowers the development cost. Java is specially used for android apps, web and application servers, games, database connections, etc. This programming language is closely related to C++ making it easier for the users to switch between the two.

A database is a collection of data and information which makes it easy to view, access, and manage. Databases save a lot of time and can store huge amounts of data. Databases make sorting data easier and stores it in certain fields which narrows the searching criteria. A database usually contains tables, graphs, and columns to display data.

What skills help Java/J2ee Developers find jobs?

Tell us what job you are looking for, we’ll show you what skills employers want.

What skills stand out on java/j2ee developer resumes?

Dr. Brock LaMeres Ph.D.

Professor, Electrical & Computer Engineering, Director, Montana Engineering Education Research Center (MEERC), Montana State University

All companies are looking for some experience beyond the classrooms. This can be through internships or doing research at their universities. But students still need to show an acceptable GPA to show employers that they understand the fundamentals of their discipline.

What soft skills should all java/j2ee developers possess?

Sal Aurigemma Ph.D.

Associate Professor of CIS, J. Bradley Oxley Professor of Computer Information Systems, University of Tulsa

All the soft skills are important, but a few are absolutely critical in today's hybrid workforce. With the uncertainty of COVID delaying the return to the office, many companies are embracing hybrid work and/or 100% remote for some or all of their employees. Today's employees must be able to effectively communicate over a range of different modalities, both synchronously and asynchronously, while still being able to actively build and maintain relationships as they participate in one or more teams of coworkers, customers, and other stakeholders. Today's IT workers need to be honest with themselves on the work environments they can and cannot succeed within.

What hard/technical skills are most important for java/j2ee developers?

Sal Aurigemma Ph.D.

Associate Professor of CIS, J. Bradley Oxley Professor of Computer Information Systems, University of Tulsa

Students graduating with Information Systems and related degrees usually have little problem finding employment upon graduation. However, the pandemic upended that paradigm for some. For those who recently graduated and are still looking for employment, keep the faith and develop your technical skills. Developers should show prospective employers that they are familiar with agile programming methodologies and modern DevOps stacks and processes. Data analysts should be focused on presenting their ability to work with structured and unstructured data, effectively query data using SQL & NoSQL, and, most importantly, provide actionable insight by making data accessible and relatable to decision-makers at all levels of an organization. Those interested in cloud architecture and cyber security careers have to keep current on their skills and certifications. Cloud engineers need to stay aware of the constant changes happening at the major providers (AWS, Azure, GCP) and, as with all other IT fields, provide tangible evidence of your skills via real projects that you have worked on. Prospective cyber security analysts should first focus on identifying their first specialization because there are too many security roles to learn them all at once, especially as beginners. Two popular entry-level cyber security jobs include information security consultant and Security Operations Center (SOC). Both of these roles require a sound foundation in networking fundamentals, vulnerability identification and mitigation, and an understanding of organizationally relevant security and privacy frameworks and regulations.

What java/j2ee developer skills would you recommend for someone trying to advance their career?

Dr. Tao Ju

Vice Dean for Research & Professor, Washington University in St. Louis

Graduates should research their targeted industries, companies and positions to identify which skills are in highest demand. Every job description has required qualifications and a desired qualifications section. The focus should be on trying to develop those desired qualifications. This could include learning a new programming language or working towards a certification (EIT, LEED, Six Sigma, etc.). Having said that, the specific skills themselves are less important than demonstrating the drive, passion and curiosity to continue developing. Do something. Take a course, volunteer, take on a short-term project, or teach yourself new software. The more graduates have developed their technical and transferable skills (leadership, communication, teamwork, adaptability, problem solving, etc.), the more competitive they will be as they enter the job market, and the quicker they will make a difference in an organization.

What type of skills will young java/j2ee developers need?

Dr. Simone Ludwig

Professor and Interim Chair, North Dakota State University

The different roles our students take on once they complete our program are developer, programmer, software engineer, and development analyst positions. All of these positions involve some type of software development, be it on the front end, e.g. application development, or on the back end programming server or database applications. Besides the technical skills, the ability to communicate well and to work individually but also collaborate in a team environment are important.

What technical skills for a java/j2ee developer stand out to employers?

Bob Sweeney Ph.D.

Associate Professor, University of South Alabama

Strong database skills including big data and SQL are always valued by local employers hiring our IS majors. While not technical, written and verbal communications skills are always important.
