This applet shows 3 GUIs that enforce validation of input data, which is so important for any application running on line.

The first GUI requires a string of a defined length, the second GUI requires a percentage to the range and accuracy specified, and the 3rd GUI enables a valid date time group to be selected.

This Java applet has been created using jdk1.5.0_02. It has the class structure shown in the UML diagram.
