Below is a java code for a coffee shop. i need the UML diagram for all the classes in this code.(jGRASP or NetBeans will be used to run and test the application) Also a brief description of the class. At the start of each method, there should also be a comment clearly describing what the method does. Each class should be fully documented commencing with a heading.
