Go from core Java and OOP to a full-stack portfolio: a console app, a Spring Boot REST API, and a Spring Boot + React application.
Set up your Java environment and learn the core syntax: variables, control flow, methods, and arrays.
- Setting up the JDK and running your first Java program
- Variables, primitive types, and operators
- Control flow: if/else, switch, loops
- Working with arrays and methods
- Basic input/output and debugging
