1）This question involves identifying and processing the digits of a non-negative integer. The declaration of the Digits? class is shown below. You will write the constructor and one method for the Digits class.

1. Write the constructor for the Digits class. The constructor initializes and fills digit List with the digits from the non-negative integer num. The elements in digit List must be Integer objects representing single digits, and appear in the same order as the digits in num. Each of the following examples shows the declaration of a Digits object and the contents of
   digit List as initialized by the constructor.
   Complete the Digits constructor below.
2. Write the Digits method isStrictlyIncreasing. The method returns true of the elements of digitList appear in strictly increasing order; otherwise, it returns false. A list is considered strictly increasing if each element after the first is greater than (but not equal to) the preceding element.
