Can we sort both LinkedHashSet and LinkedHashMap ?Since they are ordered by insertion.Also if we can,can we use both Comparable and
Comparator?
thank you

No, you cant sort ! Use TreeSet and TreeMap instead.

What if the scjp question has sorting for these both?Is it a runtime exception?

That is a good exam tricky question. Collects.sort(...) can be used to sort a list. The parameter of the sort() methods is a List<T> , not any other type. I tried to pass a hashset to Collections.sort(), but it won't compile.
