Question

Guava biMap for bi directional map, but do we have any thread safe bi directional map ?

Answer 1

There is Maps.synchronizedBiMap(BiMap) in Guava which provides some conditional level of thread-safety. The JavaDoc warns that you will have to manually synchronize on the map when using any of the views.

You could also use an ImmutableBiMap which should be thread-safe.
