Hot Ticket: The Java Programming Jobs Outlook
Java remains one of the most popular coding languages in the world. As noted by Small Business Trends, more than 80,000 jobs in the U.S. require Java coding skills, and recent survey data from the IEEE puts Java as the second-most popular coding language in the world this year.
As a result, Java coding skill is a hot ticket — skilled Java professionals enjoy a host of occupational opportunities as organizations look to build out in-house application stacks. Here’s a look at the Java programming jobs outlook with a quick overview of Java use cases, potential career options, learning curves, and the key Java skills needed to succeed in this competitive coding market.
What is Java Programming Used For?
Java was created in 1982 by Sun Microsystems. It’s an object-oriented programming language, which focuses more on the digital “objects” that contain code logic than the logic itself. This makes it possible for experienced Java programmers to quickly create or modify existing code and build powerful, customizable functions and features.
It’s no stretch to say that Java is ubiquitous. From websites to applications to mobile device frameworks, Java is everywhere; estimates suggest that more than 12 billion devices worldwide use Java code in some capacity. Java is adaptable, portable, and easily maintainable, making it one of the world's most sought-after code qualifications.
Some common use cases for Java code include:
- Android applications
- Financial service apps
- Web applications
- J2ME apps
- Embedded space applications
- Big data technologies
- Scientific software solutions
Potential Java Programming Jobs
It’s one thing for IT pros to say they have some Java experience — almost all IT professionals have encountered Java in some capacity during their work. It’s another to demonstrate Java certification; this speaks to both the skills and knowledge necessary to take new Java projects from start to finish or incorporate Java frameworks into existing IT stacks.
For Java-certified experts, there are a host of job opportunities available, such as:
Programmer (Junior/Senior) — Depending on experience, IT pros can find work as a Junior or Senior Java programmer. This job typically includes coding, debugging, code reviewing, and drafting technical documentation for Java apps and services.
Java Architect — For more experienced Java programmers, architect job tracks offer the chance to design Java applications in consultation with clients and customers.
Back-End Developer — For technology pros who prefer working behind the scenes, back-end developers manage web, database, and application servers that use Java. This job also requires experience in areas such as SQL, JSP, and REST services development.
Mobile App Developer — Billions of Android devices use Java, and the market for mobile apps continues to expand, creating a massive opportunity for skilled Java programmers.
Embedded Devices Developer — From routers to network appliances and entertainment technologies, embedded Java code is gaining ground and creating new job options.
Is Learning Java Hard?
Java is a mature programming language, which means it has a massive amount of documentation and an extensive code library.
This puts Java in the middle of the pack, among other programming languages. While it’s often considered much easier to learn than older languages such as C++, it’s generally more complex than newcomer Python. Its lengthy syntax is typically the reason that new programmers struggle with Java — although its object-oriented nature makes it more customizable than some other languages, the scale of its syntax is often daunting.
Key Java Programming Skills
It’s possible to gain a functional understanding of Java in 10-12 weeks, but code mastery takes significantly longer. Java certification makes it clear to potential employers that prospective staff has put in the time and effort to learn key Java skills and expand their programming expertise.
While there’s no skill or experience prerequisite to challenging the Java Foundations exam, IT pros are well-served by building their skill and knowledge set before taking the test. One option here is leveraging free Java programming resources available online to improve with specific Java skills. The challenge? Finding relevant information on-demand — some resources may include advanced concepts, while others may be too basic.
Online Java training courses can help fastrack Java coding development with a sequential focus on key skills, including:
- Java basics — From creating at Java program to understanding user input and variables, the ideal Java introduction is interesting, not overwhelming.
- Classes in Java — Including both class overviews and constructors.
- Control flow and structures — If statements, for loops, count programs and while loops are critical for Java coding.
- Methods — Method skills include parent and child interactions, along with method and math overloading.
- Key concepts — These include Java code inheritance, encapsulation, polymorphism, and abstraction.
Bottom line? Java remains one of the most popular coding languages in the world — and with good reason. Used in everything from embedded technologies to website apps and mobile devices, Java jobs are now a hot ticket for skilled and certified IT professionals.
