Write a Java full program that implements a Queue. Your program will ask users to input letters then it will print those letters.

Write a procedure that generates a drinking glass from a contour by creating a solid of revolution and saves it as data-files/model/glass.off. You may make a user interface for the contour parameters, but are not required to. Make a number box that selects the number of rotational slices and a button labelled “Generate” that launches the generator. Display a message on screen while generating and then flush the G3D::ArticulatedModelcache, and reload the current scene on completion. The glass must have nonzero thickness for the bowl part that contains the liquid. It cannot have any “exposed backfaces”. The glass must have a stem or thick base that is not penetrated by an inner well (i.e., you can't just double all surfaces). The glass must be geometrically closedand water tight (i.e., it should topologically be a sphere)
