John Zukowski

There are three new implementations:

• LinkedHashSet
• LinkedHashMap
• IdentityHashMap

One marker interface:

• RandomAccess

And six new utility methods for the Collections class:

• rotate(List list, int distance)
• replaceAll(List list, Object oldVal, Object newVal)
• indexOfSubList(List source, List target)
• lastIndexOfSubList(List source, List target)
• swap(List list, int i, int j)
• list(Enumeration e)
