If you are a beginner or experienced level programmer, you should have knowledge about working with cross-platform software for better career opportunity and growth in software development. When a product is designed or developed it is expected to run on multiple platforms like Windows, Mac, Linux, etc. In a simple language cross platform allows you to write code once and that is shared across different platforms.
As you learn Java, you should also start improving your project management skills. During this step, you should focus on planning, designing, and building small-scale projects with Java. Managing small projects will help you develop your system architecture and management skills (as well as give you some projects to show potential employers during job interviews).
Step 2: Keep Practicing Java
In this article, we will discuss some important Software developer skills you should have as a developer or if you are planning to become a Software developer. In her free time, she plays with her Persian cat, and she loves fishkeeping. For starters, you obviously need to master Core Java, including Java 8 features, also known as Java functional programming.
If you are looking for a career switch into the technical side, java is one of the most essential skills. For skill-specific roles, one shall prepare and have projects using those specific skills. For Example Java Web Service, REST API, SOAP API, JSON, XML, and other relevant topics. Java Web FrameworksSupports developing web applications i.e. web services, web resources, and web APIs to build and deploy web applications on the World Wide Web. One of the primary requirements is to complete a Bachelors’s/Masters’s Degree in Computer Science / Information Technology with a focus on software development.
What to Know Before Becoming a Java Developer
You can become a good software developer if you know how data can be organized and how it can be used to solve a real-life problem. As a developer a computer science student or a self-taught programmer, you should put serious effort into learning Data Structures and Algorithms(e.g. array, linked list, tree). Every good Java developer (and backend developer) is well-versed in Java SE, and while mastery won’t happen overnight, you should java 7 certifications start familiarizing yourself now with its features and terminology. Java SE provides the foundation for developing and deploying general purpose Java applications on desktops and servers. As a Java developer, you should understand key SE concepts like loops, arrays, operators, and Object Oriented Program systems (OOPs). You should also become familiar with Java SE’s general-purpose APIs, like java.lang, java.math, java.io, etc.
If you are wondering what to learn to become a successful Java developer, the trick is to apply the components learned in Core Java, so that you can do it to become a Java expert. As you will learn the language constraints and recommended design principles, you will understand that it is simple to offer a theoretical fix to a problem. But, the challenges come from actually putting the idea into practice.

But with certifications and a strong portfolio, you have a good chance of earning a job as a Java developer. Java developers earned a median salary of over $120,000 in 2021, according to the BLS. This is much higher than the median annual wage of $45,760 for all U.S. jobs. You can also freelance for companies or develop your own Java projects. Roadmap.sh is the 6th most starred project on GitHub and is visited by hundreds of thousands of developers every month.
Focus on relational databases, such as MySQL, PostgreSQL, Redis, and MariaDB as well as tools like Hibernate and OpenJPA. After building a foundation in Core Java, you need to learn Advanced Java to create web-based applications. Advanced Java includes database connectivity, servlets, and Jakarta Server Pages.
