This project hosts the utilities written in Java by Haochen. Those utilities are written for different reasons and each of them are not significant enough to be hosted in its own project.
Different utilities are organized in different Java packages, and some generic utilities are residing in the *.jutilities.utilities package.
There is also a GUI entry point, the name.haochenxie.jutilities.app.Gui class, which will give a list of utilities accessible with its own GUI.
This utility enables one to create a spectrum chart from wavelength data. It is accomplished with an easy-to-use GUI. Some more information about its usage could be found in the tooltip of the data entry area.
