Advanced Programming Concepts (Java)

Description:
This course builds on foundational programming skills and introduces object-oriented programming (OOP), design patterns, error handling, file I/O, and Java’s rich API, preparing you for building enterprise-grade applications.

Learning Objectives:

  • Master object-oriented programming (OOP) in Java

  • Understand Java collections, generics, and multithreading

  • Handle exceptions and file operations

  • Work with Java libraries and frameworks

Detailed Content:

11.1 Introduction to Java

  • Java is a compiled, platform-independent, object-oriented language.

  • Install Java Development Kit (JDK) and use IDEs like IntelliJ or Eclipse.

  • Understand the JVM, JRE, and JDK relationship.

11.2 Java Syntax Review

  • Variables, data types, control structures (if, while, switch).

  • Loops (for, while, do-while) and methods (void, return types).

11.3 Object-Oriented Programming

  • Encapsulation: Hiding data using private fields and public methods.

  • Inheritance: Subclass extends superclass for code reuse.

  • Polymorphism: Objects behave differently based on context (method overriding).

  • Abstraction: Hiding implementation with abstract classes and interfaces.

class Animal {
void sound() {
System.out.println("Animal sound");
}
}class Dog extends Animal {
void sound() {
System.out.println(“Bark”);
}
}

11.4 Exception Handling

  • Use try-catch-finally blocks to manage runtime errors.

  • Built-in exceptions: NullPointerException, IOException.

  • Create custom exceptions using extends Exception.

11.5 Java Collections Framework

  • Interfaces: List, Set, Map.

  • Implementations: ArrayList, HashSet, HashMap.

  • Iterating using loops, iterators, and streams.

11.6 File I/O

  • Use FileReader, BufferedReader, and FileWriter.

  • Read and write text files efficiently.

11.7 Multithreading

  • Threads allow concurrent execution.

  • Use Thread class or implement Runnable.

  • Synchronization prevents race conditions.

11.8 Java 8+ Features

  • Lambda expressions, Streams API, Optional class.

  • Functional interfaces (Predicate, Function, etc.)
