I'm 28 and graduated in 2020. I have about 3.5 years of professional experience, followed by a 2.5-year career break that began in March 2024. I want to return to IT, but I'm worried that Java will be difficult to relearn and that the growing gap is preventing me from getting interview calls. What would be the best way to rebuild my Java skills? Should I use YouTube, a structured course, an AI tutor, or another learning platform?

Being 28 is definitely not too late, and a career break of this length doesn’t make returning impossible. Don’t spend too long searching for the perfect course—choose one structured Java resource and follow it consistently. After reviewing the basics, build practical projects such as an expense tracker, task manager, or small Spring Boot API. Projects will help you regain confidence and give you something concrete to discuss in interviews. The main challenge is usually rebuilding the habit of coding and interviewing, not the gap itself.
Employers ultimately care about what you can contribute. Be ready to explain the career break briefly and honestly, then focus the conversation on your previous experience, current skills, and recent projects. Update your resume with the technologies you have refreshed and include links or descriptions of practical work that demonstrates your ability.
Use a manageable study plan instead of trying to finish a massive course. For example, spend a short session learning one concept, another session writing code without copying, and then apply it in a small project. Keep a list of topics you complete and gradually cover Java fundamentals, collections, exceptions, SQL, Spring Boot, REST APIs, testing, and basic data structures.
The most effective way to learn is by building, not by endlessly watching tutorials. Use videos or documentation to understand a topic, then immediately write a small Java program with it. Start with simple console applications, move to object-oriented projects, and then learn Spring Boot and databases. Coding challenge sites can help later, but you don’t need to solve dozens of difficult problems before starting real projects.
I’m unsure how to balance videos, theory, AI tools, and practice. I often get stuck after solving only a few coding problems, while some video courses are more than 100 hours long.
