Overview

Core Java forms the foundation of Java programming, covering essential concepts and features required to develop robust applications. This course introduces you to Java syntax, data types, control structures, and object-oriented programming (OOP) principles, including classes, objects, inheritance, and polymorphism.

Key Topics Covered:

• Java Fundamentals: Syntax, data types, variables, control statements (if, loops, switch).
• Object-Oriented Programming (OOP): Classes, objects, methods, inheritance, polymorphism, abstraction, and encapsulation.
• Advanced Java Concepts: Exception handling, multithreading, I/O handling, basic networking.
• Collections Framework: Work with Java's powerful collection classes to manage data

Course Description

Introduction to Core Java

• About Java: Overview of Java programming language, its origins, and significance.
• Features: Key features of Java such as platform independence, object-oriented, multithreading, etc.
• Environment Setup: Installing Java Development Kit (JDK), setting up an IDE (like Eclipse, IntelliJ), and configuring environment variables.
• Basic "Hello World" Program: Writing your first Java program.

Basic Fundamentals of Programming

• Data Types: Primitive types (int, float, char, boolean) and reference types (objects, arrays).
• Variables: Declaration and initialization of variables, data type compatibility.
• Conditional Statements:
  • if, if-else, else-if ladder, and nested if for decision-making.
  • Switch Case: Using switch for multiple conditional checks.
• Loop Statements:
  • For loop: Iterating through a block of code.
  • While loop: Repeating code while a condition is true.
  • Do-While loop: Ensures at least one iteration, checks condition after execution.

Core Concepts of Java

• Class: Blueprint for creating objects; defines properties and behaviors.
• Objects: Instances of classes that hold data and methods.
• Methods:
  • Functionality within a class that performs tasks.
  • Method Overloading: Defining multiple methods with the same name but different parameters.
• This Keyword: Refers to the current object of the class.
• Constructors:
  • Special method used for initializing objects.
  • Constructor Overloading: Multiple constructors with different parameters.

Object-Oriented Programming (OOP) Concepts

• Encapsulation: Bundling data (variables) and methods that operate on the data into a single unit (class).

  • Access Modifiers: private, public, protected, and default.

• Relationships:

  • Has-A Relation: Composition or Aggregation.
  • Is-A Relation (Inheritance): One class inherits properties and behaviors from another.
  • Super Keyword: Refers to the parent class’s methods and properties.
  • This vs. Super: Differences in their usage (this refers to the current class, super refers to the parent class).

• Method Overriding: Redefining a parent class method in the child class.

• Abstraction: Hiding implementation details and showing only essential features.

  • Abstract Class: A class that cannot be instantiated but can be subclassed.
  • Interfaces: Defines methods that a class must implement but without the method body.

Polymorphism

• Compile-Time Polymorphism: Also called static or early binding. Achieved through method overloading.
• Runtime Polymorphism: Also called dynamic or late binding. Achieved through method overriding.
• Overriding vs. Overloading: The key difference between method overriding and method overloading in Java.

Miscellaneous Topics

• New, Static, Final, Instance-of Operators:

  • new: Used to create objects.
  • static: Declaring static variables and methods (belong to the class, not instance).
  • final: Used for constants, methods that cannot be overridden, and classes that cannot be subclassed.
  • instanceof: Used to check the type of an object at runtime.

• Package & Import Statements: Organizing code using packages and importing required classes using import.

• Exception Handling: Using try, catch, finally, and custom exceptions to handle runtime errors.

• Multithreading: Using Thread class or Runnable interface for concurrent programming and improving performance.

• String Manipulation: String operations like concatenation, substring, length, etc., using the String class and StringBuilder/StringBuffer.

• Collections Framework:

  • Interfaces like List, Set, and Map.
  • Implementations like ArrayList, HashSet, HashMap, etc., for storing and managing collections of objects.
