Welcome to the Financial Portfolio Page

This page demonstrates how you could use applets to track the value of a few stocks. The applets on this page use pretend data, since our stock and closed caption servers are unavailable outside of Sun. The stock data is taken from a snapshot of the stock market activity on December 8, 1995.

There is now an indepth explanation of how these applets work with pointers to the source code.

Note: The applets in this page work only in viewers and browsers which support version 1.0 of the Java(tm) Programming Language.

The first applet is a stock ticker. It shows new quotes in green and old quotes in white.
The source for this applet uses the StockTicker, StockStreamParser, and StockWatcher classes.
If you want to keep better track of a stock, you might use a graph showing some historical quotes. These applets could connect (via a URL) to an HTTP server that keeps a database of stock quotes if one were configured to return the stock quote information in the appropriate format. The NEATO quotes shown below are randomly faked every 5 seconds.
The source for this applet uses the QuoteChart, StockStreamParser, and StockWatcher classes.
Finally, here's an applet that lets you check out the latest news -- as you might want to do when you see fluctuations in the marketplace. This applet could connect (via a URL) to an HTTP server that was monitoring the closed captioning information on a TV news station. Here it is simply displaying the contents of a static file, since we do not have permission to broadcast closed caption information outside of Sun.

The source for this applet uses the ClosedCaption class.

Questions?

Please read the explanation page for these applets, and note that these applets were developed as a demonstration of Java capabilities. Sun has no plans to enhance or market these applets but permission is granted to use them as a starting point for a stock quote service, provided such service is made available free of charge.

If you need help modifying these applets to work with an existing stock service, the best resources would be the comp.lang.java newsgroup or the java-interest mailing list.
