Java

Java Training Academy Curriculum. It is structured into three progressive tiers—ranging from foundational programming to enterprise-grade cloud architecture—designed to take students from absolute beginners to job-ready software engineers.

Phase 1: Core Java Foundations (Months 1–2)

Focus: Mastering the syntax, logic, and object-oriented paradigms.

Module 1: Introduction & Environment Setup

• The Java Ecosystem: Understanding the role of the JDK, JRE, and the Java Virtual Machine (JVM).

• Cross-Platform Architecture: Exploring the “Write Once, Run Anywhere” (WORA) compilation process (Source Code $\rightarrow$ Bytecode $\rightarrow$ Machine Code).

• Setup: Installing the JDK and setting up an Integrated Development Environment (IDE) like IntelliJ IDEA or Eclipse.

Module 2: Language Fundamentals

• Data Types & Variables: Primitive vs. Reference data types, memory allocation, and Type Casting.

• Operators: Arithmetic, relational, logical, and bitwise operators.

• Control Flow Structures: * Conditional Statements (if-else, switch-case).

  • Looping Structures (for, while, do-while, and enhanced for-loops).

• Arrays: Single and multi-dimensional array manipulation, sorting, and searching.

Module 3: Object-Oriented Programming (OOP)

• Classes and Objects: Defining state (fields) and behavior (methods), understanding constructor overloading, and the this keyword.

• The 4 Pillars of OOP:

  • Encapsulation: Access modifiers (private, public, protected, default) and Getters/Setters.

  • Inheritance: Extending classes using super and understanding code reusability.

  • Polymorphism: Runtime (Method Overriding) vs. Compile-time (Method Overloading) polymorphism.

  • Abstraction: Abstract classes vs. Interfaces (including Java 8+ functional interfaces).

Module 4: Advanced Core Concepts

• String Handling: Memory optimization via the String Pool, StringBuilder, and StringBuffer.

• Exception Handling: The Throwable hierarchy, try-catch-finally blocks, multi-catch, and creating custom exceptions.

• Java Collections Framework: Data structures including List (ArrayList, LinkedList), Set (HashSet, TreeSet), and Map (HashMap, TreeMap).

• Generics: Building type-safe, reusable components.

• File I/O: Reading and writing files using Streams and the NIO package.

Phase 2: Advanced Java & Backend Essentials (Months 3–4)

Focus: Concurrent programming, database integration, and modern language features.

Module 5: Multithreading & Concurrency

• Thread Lifecycle: Creating threads using the Thread class and Runnable interface.

• Synchronization: Preventing data race conditions using synchronized blocks and explicit locks.

• Concurrency Utilities: Utilizing the Executor Framework, Thread Pools, and CompletableFuture for asynchronous execution.

Module 6: Modern Java Features

• Java 8 & Beyond: Lambda Expressions, the Stream API for functional data processing, Optional class to safely avoid NullPointerException, and Record types.

Module 7: Database Connectivity (JDBC) & Build Tools

• SQL Basics: Writing relational queries, joins, and indexing (using MySQL or PostgreSQL).

• JDBC: Establishing database connections, executing statements, preventing SQL injection using PreparedStatement, and transaction management.

• Build Tools: Structuring enterprise projects using Maven or Gradle (pom.xml dependencies, build life cycles).

Phase 3: Enterprise Web Development with Spring Boot (Months 5–6)

Focus: Building production-grade microservices and REST APIs.

Module 8: The Spring Ecosystem

• Inversion of Control (IoC) & Dependency Injection (DI): De-coupling application architecture using Spring Beans.

• Spring Boot Foundations: Starters, autoconfiguration, and application properties management.

Module 9: RESTful Web Services & Data Persistence

• Spring Web MVC: Creating REST controllers, handling HTTP methods (GET, POST, PUT, DELETE), and processing JSON requests.

• Spring Data JPA / Hibernate: Object-Relational Mapping (ORM), repository interfaces, automated CRUD operations, and custom query construction.

Module 10: Testing, Security & Deployment

• Unit & Integration Testing: Writing automated tests using JUnit 5 and Mockito.

• Spring Security: Implementing basic authentication, JWT (JSON Web Tokens), and role-based access control.

• DevOps & Deployment: Containerizing the Java application using Docker and preparing it for cloud deployment.

🛠️ Practical Academy Highlights

To bridge theory and career placement, an academy syllabus should explicitly include:

• Capstones: A Full-Stack web application (e.g., E-Commerce API, Banking Portal).

• Design Patterns: Coverage of Singleton, Factory, DAO, and MVC patterns during Phase 2.

• Interview Prep: Weekly mock interview sessions focusing on Java coding standards and competitive DSA (Data Structures & Algorithms) challenges.
