A schedule example using Java Gui

I have been searching for more than one day for a way to create a university schedule that can be added to a Java GUI . However I couldn't find any example that are done with Java . I would like a master detail Schedule, The schedule actually should been drawn directly onto the JPanel using Java's built in graphics library (java.awt.Graphics). Java's graphics can then be used to draw lines and Strings. that looks like the one in the following link: https://www.facebook.com/183548125156358/photos/a.183552331822604.1073741826.183548125156358/183552395155931/?type=1&theater
