Java Generic Data Structures and Coercion (cont'd)

• Ramifications:

  • You cannot directly assign an element of one of these collections to a variable unless it is declared to have type Object
  • Most likely you will want to coerce the returned value to a more appropriate specific type

• For example, if s is an object of type Stack that holds strings then when you pop this stack you will want to coerce the result to String:

  • (String)(s.pop())
