An arithmetic progression is a sequence of numbers such that the difference between the consecutive terms is constant. For instance, the sequence 5, 7, 9, 11, 13, 15 is an arithmetic progression with a common difference of 2. Given the class IntNumber: 1 public class IntNumber 2 { 3 public final int value; 4 5 public IntNumber(int number) { 6 this.value = number; 7 } 8 } where value is an immutable field, that can be directly accessed (public), implement a class called ArithmeticProgression that implements the following methods: •1 public static IntNumber getArithmeticProgressionDifference(ArrayList< IntNumber> list) which returns the difference between terms of the arithmetic progression (as an object of type IntNumber) if the values of the IntNumber objects are an arithmetic progression. The method returns null in any other case. •1 public static void printIsArithmeticProgression(ArrayList list ) which prints on the console: The list is an arithmetic progression with difference = if the list is an arithmetic progression (replace with the actual value) or The list is not an arithmetic progression in all other cases (e.g., if one of the IntNumber in the list is null).

where value is an immutable field, that can be directly accessed (public), implement a class called ArithmeticProgression
that implements the following methods:
•1 public static IntNumber getArithmeticProgressionDifference(ArrayList<

which returns the difference between terms of the arithmetic progression (as an object of type IntNumber) if the
values of the IntNumber objects are an arithmetic progression. The method returns null in any other case.
•1 public static void printIsArithmeticProgression(ArrayList<IntNumber> list

which prints on the console:
The list is an arithmetic progression with difference = <difference>
if the list is an arithmetic progression (replace <difference> with the actual value) or
The list is not an arithmetic progression
in all other cases (e.g., if one of the IntNumber in the list is null).
