1) Both HashMap and HashSet are not synchronized which means they are not suitable for thread-safe operations unitl unless synchronized explicitly. This is how you can synchronize them explicitly: HashSet: Sets=
None of these implementation aresynchronized. That is if multiple threads access a set concurrently, and at least one of the threads modifies the set, it must be synchronized externally. LinkedHashSetis in some sense intermediate between HashSet and TreeSet. Implemented as aHashTablewith a linked...
