V SEMESTER BCA
Course: Advanced Java Programming
Course Code: 22CAC-13

Module I

Applet Output Display: The paint() method is used to display applet output.
String Output in Applet: The drawString() method is used to output strings within an applet.
AWT: Acronym for Abstract Window Toolkit, a Java API for creating graphical user interfaces.
Exception in read() method: The read() method can throw an IOException.
Input/Output Packages: The java.io package provides classes and interfaces for input/output operations.
Non-member class of java.io package: java.io.Writer is not a member class, java.io.StringReader is.
Non-input/output related class: java.io.File is not related to input/output stream functionality.
Byte Streams: java.io.InputStream and java.io.OutputStream are used for reading and writing byte data.
Character Streams: java.io.Reader and java.io.Writer are used for reading and writing character data.

Module II

Container without title bar/menu: A Panel is a container that does not have a title bar or menu bar.
Event handling package: java.awt.event provides event classes and listener interfaces for event handling.
Rectangle drawing: The drawRect(int x, int y, int width, int height) method in the java.awt.Graphics class draws a rectangle.
GUI application window: A Frame is a window that represents a GUI application and can have a title bar, icon, and menus.
ActionListener implementation: There are several ways to implement the ActionListener interface: by creating a new class, using an anonymous inner class, etc.

Module III

Graphics methods: The Graphics class provides methods for graphics programming tasks.
Label text handling: The setText() method is used to set the text displayed in a Label object.
Container layout: A Container's layout can be altered using the setLayout() method, which accepts a LayoutManager object.
Key press detection: Use the getKey() method for detecting a pressed key..
Methods invoked for button press: An ActionEvent is generated when a button is pressed.
Event handling package: java.awt.event is the package containing classes for event handling.
GUI window object: A Frame is a visible window in a GUI application.
String Label modification: The Label class has a setText() method to change the text of the label.
Passive controls: Controls like Labels are passive, they don't respond to user interaction directly.

Module IV - JDBC

Query Compilation: A JDBC query is compiled when it's prepared.
Data Transfer: JDBC's ResultSet, PreparedStatement, and CallableStatement methods handle data transfer between applications and databases.
UDA Acronym: Universal Data Access
Connection establishment: The DriverManager class's getConnection() methods establish connections to databases.
JDBC Driver Types: JDBC technology provides: JDBC-ODBC bridge, NativeAPI, NetworkProtocol, and Thin drivers.
JDBC core package: java.sql is the core package.
RMI Methods: The Naming class has methods like rebind() to manage remote objects.
Executing SQL Queries: Using the executeQuery() method to retrieve data is very common.

Module V

Cookies: Used for client-side maintaining session information. Cookies can be persistent or non-persistent (stateful or stateless).
Servlet Lifecycle Methods: init(), service(), destroy() are the primary lifecycle methods for a Servlet.
