This document contains the code for a Java application that converts a person's height entered in feet and inches to centimeters. It creates a GUI with labels, text fields, sliders and a button to trigger the conversion. When the slider values change, the stateChanged method updates the text fields. The HeightFtInToCm method performs the actual conversion calculation. The main method creates the frame and makes it visible.

1. Value isn't changing and I can't seem to get the conversion to work.package UI;import
