1. Core Java (Java SE)

  • Why It’s Important: Core Java is the foundation for any Java developer. It includes key concepts like object-oriented programming (OOP), data types, operators, control statements, arrays, strings, and exception handling.
  • Key Concepts:
    • Object-oriented programming principles (encapsulation, inheritance, polymorphism, and abstraction).
    • Java syntax and the basic building blocks of the language.
    • Memory management and garbage collection.
    • Collections framework (List, Set, Map).

Mastery of Core Java is essential for any Java developer, as it forms the basis for advanced development.

2. Advanced Java (Java EE / Jakarta EE)

  • Why It’s Important: Java EE (Enterprise Edition) or Jakarta EE adds capabilities for developing large-scale applications. This includes server-side programming, web services, and enterprise-level frameworks.
  • Key Concepts:
    • Servlets and JSP (JavaServer Pages).
    • Enterprise JavaBeans (EJB).
    • Java API for RESTful Web Services (JAX-RS).

Understanding Java EE is critical for developers working on enterprise applications and web services.

3. Spring Framework

  • Why It’s Important: The Spring Framework is one of the most widely used Java frameworks for building enterprise-level applications. It provides a comprehensive programming and configuration model for modern Java-based systems.
  • Key Concepts:
    • Spring Core and Dependency Injection (IoC).
    • Spring MVC for building web applications.
    • Spring Boot for simplifying application configuration and deployment.
    • Spring Data for interacting with databases.
    • Spring Security for adding authentication and authorization to applications.

Proficiency in Spring is a must for Java developers working on modern applications, especially in enterprise environments.

4. Hibernate ORM (Object-Relational Mapping)

  • Why It’s Important: Hibernate is a powerful tool that simplifies database interactions by mapping Java objects to database tables. This eliminates the need for complex SQL queries.
  • Key Concepts:
    • Understanding how to map Java classes to relational databases.
    • Configuring Hibernate sessions and transactions.
    • Writing HQL (Hibernate Query Language).
    • Managing relationships between objects (one-to-one, one-to-many, etc.).

Hibernate is a vital skill for backend developers dealing with database management in Java applications.

  • Why It’s Important: Java developers are often tasked with creating APIs for web services. REST (Representational State Transfer) is the standard for designing networked applications.
  • Key Concepts:
    • Building and consuming RESTful APIs using frameworks like Spring Boot.
    • Understanding HTTP methods (GET, POST, PUT, DELETE).
