The document is about using ImageIcon, JPanel, and Timer classes in Java.
It contains 3 sections:
1) Using ImageIcon and JPanel composition to display different images by clicking buttons.
2) Using inheritance with JPanel and Timer to create an animation class that displays a sequence of images.
3) Using Timer and JPanel to create a clock class that displays the time and updates every second.

The document discusses using mouse and keyboard events in Java programs. It provides examples of using MouseListener and MouseEvent to detect mouse clicks on objects. It also demonstrates using MouseMotionListener to handle mouse drag and move events. Keyboard events are handled using KeyListener. The examples show drawing shapes by clicking buttons or keys, and changing shape properties by clicking or dragging the mouse.

1) The document discusses creating Java applets and using classes in an applet. It includes examples of creating classes to calculate compound interest, graph mathematical functions, and create a timer applet.
2) The examples create classes like Invest and Graph that perform calculations and drawing. They are used in applets that allow users to set inputs and see results updated.
3) The timer applet example uses the Timer class from Swing to repeatedly repaint random colored circles on a schedule.

This document discusses class design using inheritance and garbage collection in Java. It describes a Point class with x and y coordinates and a Rectangle class that inherits from Point and adds width and height properties. Code examples show defining the classes, creating Point and Rectangle objects, and drawing them in an applet. The Rectangle class inherits coordinate properties from Point and adds its own methods while Point's static count property tracks the number of objects.

The document discusses class design using composition for a student registration system. It defines classes for Student, Subject, and Register to store student and subject data, as well as a registration between them. Code examples are provided to demonstrate creating objects from these classes and storing registration data by composing a Student and array of Subjects within a Register object.
Applet 2 container and action_listener
The document provides instructions for creating a basic calculator application using Java applets and GUI components. It describes how to:
1. Create a ConApplet class that extends JApplet.
2. Add a JLabel, JTextField, and four JButtons (for numbers 1 and 2, plus sign, equals sign) to the applet's content pane.
3. Make the number buttons update the JTextField by concatenating the number to the existing text when clicked.
4. Declare three private int variables (num1, num2, ans) to store the calculation values.
The document guides the reader through setting up the basic GUI elements and behaviors for a simple two-number
Putty basic setting
PuTTY is an open source SSH and telnet client originally developed by Simon Tatham for Windows. The document provides instructions for basic telnet configuration in PuTTY, including entering an IP address and port, naming the session, setting the session to remain active for 100 seconds, changing the appearance, and saving and opening the connection.
