Your complete guide to mastering the enterprise world's favorite stack. Learn Core Java, Spring Boot, and React/Angular step-by-step.
1. Master Core Java
💡 Teacher's Tip: This is the most crucial step. Don't rush into frameworks. You must understand OOPs (Inheritance, Polymorphism), Collections, and Multi-threading deeply.
💡 Teacher's Tip: You are a Full Stack dev, not just Backend. You must know how the browser works. Master the "Big Three": HTML structure, CSS layout (Flexbox/Grid), and JavaScript logic.
💡 Teacher's Tip: Java apps run on data. Learn to write complex SQL queries. Understand Primary Keys, Foreign Keys, and Joins. MySQL or PostgreSQL are great starting points.
💡 Teacher's Tip: This is where you become a professional Java Developer. Spring Boot automates the heavy lifting. Learn Dependency Injection (IoC), JPA for database connection, and creating REST APIs.
💡 Teacher's Tip: Connect your Java backend to a modern UI. React is the most popular, but Angular is also common in Java enterprises. Pick React for easier learning curve.
💡 Teacher's Tip: Knowledge is useless without application. Build an "E-commerce Store" or "Employee Management System". Connect React to Spring Boot to MySQL.
