SWE 332 Assignment 11
Fall 2020

Goal: Generics.

Consider a flyweight version of the ImmutableStack.java.

Your assignment is to:

• Make ImmutableStack generic.
• Add a method that allows multiple elements to be enqueued at once. The ungeneric signature of this method is:

        public void putAll (Collection c) throws ...
  

  This method might throw various exceptions. You should think through - and document, with Javadoc or postconditions - all of the possibilities.
  Of coure, you should also generify this method. See Bloch Item 28 to get the details right.
• Your code should not through any warnings during compilation. That is, either your code is typesafe, or you have, with justification, suppressed any warnings as needed.
• There is no explicit override of either equals() or hashcode(). This is both correct and desirable. Explain why on both counts.

Grading Criteria:

• Error-free and warning-free compilation.
• Implementation of generics.
• putAll method (both code and documentation).
• Reasonable discussion of equals() and hashcode().
• Bonus point if you get a warning-free compilation without suppressing any warnings.
