implements ArgumentConverter

DefaultArgumentConverter is the default implementation of the ArgumentConverter API.

The DefaultArgumentConverter is able to convert from strings to a number of primitive types and their corresponding wrapper types (Byte, Short, Integer, Long, Float, and Double), date and time types from the java.time package, and some additional common Java types such as File, BigDecimal, BigInteger, Currency, Locale, URI, URL, UUID, etc.

If the source and target types are identical the source object will not be modified.
