Question

. Design a class named MyInteger. The class contains: An int data field named value that stores the int value represented by this object. A constructor that creates a MyInteger object for the specified int value. A getter method that returns the int value. The methods isEven(), is Odd(), and isPrime() that return true if the value in this object is even, odd, or prime, respectively. The static methods isEven(int), isOdd(int), and isPrime(int) that return true if the specified value is even, odd, or prime, respectively. The static methods is Even(MyInteger), is Odd(MyInteger), and isPrime(MyInteger) that return true if the specified value is even, odd, or prime, respectively. The methods equals(int) and equals(MyInteger) that return true if the value in this object is equal to the specified value. A static method parseInt(char[]) that converts an array of numeric characters to an int value. A static method parseInt(String) that converts a string into an int value. . . . . Draw the UML diagram for the class then implement the class. Write a client program that tests all methods in the class.
