Join a list of strings in python and wrap each string in quotation marks
...look', 'nice'] * 100; '"{}"'.format('", "'.join(words))""").timeit(1000)

Convert java.util.Date to java.time.LocalDate
...l data stored within the object is a long count of milliseconds since 1970-01-01T00:00Z (midnight at the start of 1970 GMT/UTC).
