Modeling a Domain (UML→Code)
Turn a tiny problem description into classes, fields, and methods. Read a simple UML sketch and implement it in Java.
What is domain modeling?
Domain modeling means describing the problem with classes and relations that match the real world. Keep it small: choose 2 or 3 core concepts and write down what each knows and does.
Nouns, verbs, relations
Underline nouns to propose classes and underline verbs to propose methods. If one thing uses or contains another, that suggests a has a field. This simple routine turns text into a class list.
