(The EvenNumber class) Define the EvenNumberclass for representing an even number. The class contains:

• A data field value of the int type that represents the integer value stored in the object.
• A no-arg constructor that creates an EvenNumber object for the value 0.
• A constructor that constructs an EvenNumber object with the specified value. (Note: If it is not an even number, add 1 to make it an even number.)
• A function named getValue() to return an int value for this object.
• A function named getNext() to return an EvenNumber object that represents the next even number after the current even number in this object.
• A function named getPrevious() to return an EvenNumber object that represents the previous even number before the current even number in this object.

Submit the following:

1. Draw the UML diagram for the class, EvenNumber. Refer to the textbook example for the Circle class's UML diagram - Figure 9.3 (2 points)
2. Implement the class, EvenNumber. (6 points)
3. Write a test program that creates an EvenNumber object for value 16 and invokes the getNext() and getPrevious()functions to obtain and display these numbers. The program need not expect any input from the user. Also, test the constructor with value 5. Display its getNext() function. (2 points)
