Simple Java Applet

·Buttons.java demonstrates an applet with some buttons. Clicking the Square button displays a square in the center of the applet, clicking the Circle button displays a circle, etc. This applet uses the JDK 1.1 ActionListener model to sense events.

Jan's Craps in Java

·DiceDemo.java extends applet and uses the ActionListener, switches, a random number generator is behind the Roll Dice button, and I create my own class for the Die used in the craps game.

Applet to Calculate a Monthly Loan

·MonthlyLoanPayment.java demonstrates an applet using the Layout Manager, text components, the getText() and setText() methods.

State Maps Applet

·pics.java extends applet and uses the ItemListener, and two dropdown combo boxes. When the user chooses a state the image is updated and the cities for that state are loaded into the cities combo box. Clicking on a city puts location on the state map. A multi-dimensional array is used for the cities and getImage() is used for the graphics which is in the java.net library.

Simple Drawing Program

·Draw.java demonstrates an applet with a "roll-your-own" toolbar and is a simple rubber-banding demonstration. Class variables x1, y1 hold the anchored button-down point, while x2, y2 hold the current mouse points. Use a state variable to track the drags in process through WAITING --> DRAGGING --> WAITING. When dragging, mouseDrag sets XOR drawing mode, then erases the last figure and draws the current one to give the rubberband effect.
