What is the best way to get from John F. Kennedy airport to Brooklyn public transportation please?

The best way to get from John F. Kennedy Airport (JFK) to Brooklyn using public transportation is to take the AirTrain JFK to the Jamaica Station. From there, you can transfer to the Long Island Rail Road (LIRR) for a quick ride into Brooklyn or take the subway (E or J trains) depending on your destination. Alternatively, you can take the subway directly from the airport by using the A train from Howard Beach Station.
