Java Programming – OOP, Multithreading & Database Connectivity

These notes introduces Java as a platform-independent, object-oriented language widely used in web and enterprise applications. Students begin with core syntax, classes, objects, arrays, and constructors, then progress to inheritance, interfaces, and packages for code reusability. Exception handling and multithreading are covered in depth, teaching students to build robust, concurrent applications. A significant portion focuses on GUI development using AWT and Swing components, event handling, and layout managers to create interactive desktop applications. The course also introduces network programming with sockets, InetAddress, and URL classes, followed by database connectivity using JDBC, including drivers, connections, and ResultSet operations. With hands-on micro-projects like ATM systems, quiz management, and employee databases, this subject equips students with practical, industry-relevant Java development skills applicable to standalone and networked applications.
