分享一道oo design方面的题目，请大家帮忙看下。
Your task, for this question, is to construct a conceptual model of the Java type system. It captures the relationships between classes and interfaces, and between the declared types of Telds and the types of the objects they hold. It ignores primitive types and local and static variables.
