Java to UML Class Diagram

Convert this Java code to a UML class diagram. This Java code is meant to represent a mouth tasting and consuming food. There are food, flavours, tongues, and taste buds.

Draw a well-designed UML class diagram to represent this information. Provide the basic abstractions, attributes, methods, relationships, multiplicities, and navigabilities as appropriate. "...” means much code is omitted.
