1. Introduction to Java
History and Evolution: Understanding the origins and development of Java.
Features of Java: Platform independence, object-oriented, simple, secure, etc.
Java Environment: JDK (Java Development Kit), JRE (Java Runtime Environment), and JVM (Java Virtual Machine).
2. Basic Syntax
Java Program Structure: Understanding the structure of a Java program including the main method.
Data Types: Primitive data types (int, char, double, boolean, etc.) and non-primitive data types (arrays, strings, classes).
Variables: Declaration, initialization, and scope of variables.
Operators: Arithmetic, relational, logical, bitwise, assignment, and other operators.
3. Control Flow Statements
Conditional Statements: if, if-else, switch.
Looping Statements: for, while, do-while loops.
Branching Statements: break, continue, return.
4. Object-Oriented Programming (OOP) Concepts
Classes and Objects: Creating classes and objects, understanding the relationship between them.
Methods: Defining and invoking methods, method overloading.
Constructors: Default and parameterized constructors.
Inheritance: Extending classes, the use of super keyword, method overriding.
Polymorphism: Compile-time (method overloading) and run-time (method overriding) polymorphism.
Encapsulation: Using access modifiers to protect data.
Abstraction: Abstract classes and interfaces.
5. Java Libraries and APIs
String Handling: String class and its methods, StringBuilder, and StringBuffer.
Collections Framework: List, Set, Map, and their implementations like ArrayList, HashSet, HashMap.
