I'm 28 and graduated in 2020. I have about 3.5 years of professional experience, followed by a 2.5-year break that began in March 2024. I want to return to the IT industry, preferably as a Java developer, but I'm worried that the growing gap will make it harder to get interviews. Java also feels intimidating to restart from scratch. Should I learn through YouTube, a Udemy course, books, AI tools, or hands-on practice? I often get stuck after solving only a few LeetCode or HackerRank problems, and many video courses are extremely long. What would be a practical learning and job-search plan?

Employers ultimately want to know what value you can bring, not just how long your break was. Update your résumé to highlight your previous experience, explain the break briefly and neutrally, and add current projects, technologies, and measurable accomplishments. Apply while learning rather than waiting until you feel completely ready. Networking, referrals, and smaller companies may also give you better opportunities than relying only on online applications.
The most effective way to learn Java is by making applications, not by endlessly searching for the perfect tutorial. Review the fundamentals—syntax, object-oriented programming, collections, exceptions, SQL, and basic testing—then create a small application and improve it feature by feature. A graphical interface isn’t necessary; a command-line program or backend API is enough to show practical ability.
At 28, you’re definitely not too late to return. Choose one structured Java course and stick with it instead of comparing every available resource. Learn the basics through short lessons, then spend most of your time building projects. A simple expense tracker, task manager, or REST API with Spring Boot would give you something concrete to discuss in interviews. The gap matters much less when you can clearly demonstrate what you know and what you’ve built.
You don’t need to watch a 100-hour course from beginning to end. Use videos or AI explanations when you’re confused, but write code after every small topic. Start with tiny exercises before attempting difficult algorithm problems, and gradually work up from arrays and strings to more advanced questions.
