                          TemporalUnit unit)

Parameter: This method takes the following argument as a parameter:

  • amountToSubstract: which is the value of temporal unit which is going to substracted from the current Japanese date.

            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
