Subject Overview

A practical introduction to modern Java programming covering language fundamentals, object-oriented design, data handling, application development, quality assurance, security, frameworks, and contemporary industry practices.

Learning Goal

Students will be able to design, implement, test, debug, secure, and maintain Java applications using sound programming principles, standard tools, libraries, and responsible professional practices.

Syllabus

1. Java Ecosystem and Development Environment

Learning Objective: Explain Java terminology and architecture, including the JDK, JRE, JVM, bytecode, portability, compilation, execution, IDEs, command-line tools, and modern Java release practices.

Category: foundation

2. Language Syntax, Variables, and Data Types

Learning Objective: Write basic Java programs using classes, the main method, identifiers, primitive and reference types, variables, constants, operators, type conversion, input, output, and coding conventions.

Category: foundation

3. Control Flow and Problem Solving

Learning Objective: Apply algorithms, pseudocode, Boolean logic, selection statements, loops, validation, and basic complexity awareness to solve structured programming problems.

Category: foundation

4. Methods, Arrays, Strings, and Modular Programming

Learning Objective: Create reusable methods using parameters, return values, scope, overloading, recursion fundamentals, arrays, multidimensional arrays, strings, and common utility classes.

Category: core

5. Classes, Objects, and Encapsulation

Learning Objective: Model real-world entities with classes and objects; use fields, methods, constructors, access modifiers, static members, packages, encapsulation, immutability, and records where appropriate.

Category: core

6. Inheritance, Interfaces, and Polymorphism

Learning Objective: Apply inheritance, composition, abstract classes, interfaces, method overriding, polymorphism, sealed classes, and SOLID-oriented design to build extensible applications.

Category: core

7. Exceptions, Debugging, and Program Reliability

Learning Objective: Handle errors using exception hierarchies, try-catch-finally, try-with-resources, custom exceptions, assertions, logging, debugger tools, and defensive programming.

Category: core

8. Collections, Generics, and Data Structures

Learning Objective: Use generic types and the Java Collections Framework, including lists, sets, maps, queues, iterators, comparators, and appropriate collection selection based on performance needs.

Category: core

9. Functional Java and Stream Processing

Learning Objective: Use lambda expressions, functional interfaces, method references, Optional, streams, collectors, and parallel-stream awareness for declarative data transformation and analytics.

Category: application

10. Files, Data Formats, and Persistence

Learning Objective: Read and write files using Java I/O and NIO; process paths, text, binary data, JSON concepts, object serialization risks, and persistence requirements responsibly.

Category: application

11. Concurrency and Asynchronous Programming

Learning Objective: Explain threads, process models, synchronization, race conditions, deadlocks, executors, futures, concurrent collections, virtual threads, and safe concurrent design.

Category: advanced

12. Databases and JDBC

Learning Objective: Connect Java applications to relational databases using JDBC, execute parameterized queries, manage transactions, map results, prevent SQL injection, and support data-driven decision making.

Category: application

13. Testing, Build Tools, and Software Delivery

Learning Objective: Develop reliable software using unit testing, JUnit, test design, Maven or Gradle, dependency management, Git, documentation, code review, continuous integration, and basic deployment workflows.

Category: application

14. APIs, Security, and Enterprise Frameworks

Learning Objective: Understand HTTP, RESTful services, client-server architecture, authentication, authorization, secure coding, dependency risks, and the role of Spring Boot and related enterprise frameworks.

Category: contemporary

15. Contemporary Java Practice and Capstone Application

Learning Objective: Integrate requirements, design, implementation, testing, and deployment in a small application while considering cloud-native Java, containers, AI-assisted development, ethics, privacy, licensing, governance, maintainability, digital transformation, and emerging Java trends.
