Arrays in Java

Working with one-dimensional, two-dimensional and multidimensional arrays, array iteration, common operations, and Arrays utility class.

Strings & String Handling

String class, string methods, mutable strings using StringBuilder and StringBuffer, string comparison, tokenizer, and regex basics.

Object-Oriented Programming (OOP)

Core OOP concepts including classes, objects, constructors, methods, access modifiers, packages, encapsulation, abstraction, static and this keyword.

Inheritance & Polymorphism

Types of inheritance, method overloading and overriding, super keyword, dynamic method dispatch, final keyword, and instanceof operator.

Interfaces & Abstract Classes

Creating interfaces, multiple inheritance using interfaces, functional interfaces, abstract classes, and comparison between interface and abstract class.

Exception Handling

Error types, try-catch-finally blocks, throw and throws keywords, custom exceptions, exception hierarchy, and handling multiple exceptions.

Java Collections Framework

Collections framework including List, Set, Map interfaces, ArrayList, LinkedList, HashSet, TreeSet, HashMap, TreeMap, iterators, Comparable and Comparator.

File Handling in Java

File class usage, reading and writing files, streams, buffered readers and writers, serialization and deserialization.

Multithreading

Thread creation using Thread class and Runnable interface, thread lifecycle, synchronization, inter-thread communication, priorities and daemon threads.

Java GUI (Swing & AWT)

GUI development using AWT and Swing components, layout managers, event handling, and basic GUI applications.

Java Networking

Networking fundamentals including sockets, server-client communication, URL handling, HttpURLConnection, and Java networking APIs.

JDBC (Database Connectivity)

JDBC architecture, connecting Java with MySQL, Statement and PreparedStatement, ResultSet handling, CRUD operations and SQL exception handling.

Lambda Expressions & Functional Programming

Lambda expressions, functional interfaces, Streams API, forEach, filter, map, reduce operations and method references.
