Before diving into Spring Boot, make sure your Java fundamentals are solid. Frameworks don’t replace fundamentals, they assume them. If interfaces, collections, or HTTP basics still feel unclear, Spring will only amplify that confusion. Master the basics first. Everything else becomes easier. #Java #SpringBoot #SoftwareEngineering #BackendDevelopment #Programming
I have been learning java for some time now, and I am currently on: Java File I/O Streams, Custom exception, Chained Exception (SQL exceptions) like learning to create my own exceptions, understanding Exception class and why to extend from it, to Checked and Unchecked Exceptions and I am moving to Java concurrency like how to create basic program using threads, understanding Thread Life Cycle. then after I will be moving to Collections
100% this. I've seen developers who can wire up a Spring Boot app in minutes but struggle to explain why ArrayList vs LinkedList matters for their use case, or what's actually happening when an interface reference points to an implementation. The framework hides so much that you can go months without realising there's a gap. Personally the moment things clicked for me was when I stopped reading framework docs and went back to core Java concurrency, suddenly a lot of Spring's design decisions made complete sense.
