Generics and Inheritance: Notes

Generics and Inheritance Notes

Generics can be used with inheritance in several ways:

  • A generic class can be derived from a non-generic class. For example, the Object class is a direct or indirect superclass of every generic class.
  • A generic class can be derived from another generic class. For example, generic class Stack (in package java.util) is a subclass of generic class Vector (in package java.util). We discuss these classes in Chapter 19, Collections.
  • A non-generic class can be derived from a generic class. For example, non-generic class Properties (in package java.util) is a subclass of generic class Hashtable (in package java.util). We also discuss these classes in Chapter 19.
  • Finally, a generic method in a subclass can override a generic method in a superclass if both methods have the same signatures.
