       GSON library is required, if for some reason you cannot import
       this library, delete the toJSON () method The library will no
       longer be needed, but then you will lose the ability to convert
       the list into a JSON string  This is a list that can store both
       values and other lists.  The list can store any type of values,
       but only the one that was set in the original list (in fact, it
       is easy to manage, but it's better not to risk it) The code was
       tested in Processing 3 (A program using Java-based language, so
       that for those who know Java, this program will be easy) and
       everything works perfectly ...
