Create a class Decreasing Number with the method is Decreasing() to check if the given number is a decreasing number or not. (A decreasing number is a positive integer of two or more digits, all of which are written in strictly decreasing order reading from left to right. For example, 532 is a decreasing number, but 511 and 417 are not). Read the number as a command line argument. If the given number cannot be converted into a valid integer number raise "NumberFormatException" and if the given number is not a decreasing number, throw an user defined exception "InvalidDecreasing NumberException".
