Question
The problem is: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 get method that returns the int value.
* Methods isEven(), isOdd(), and isPrime() that return true if the value is even, odd, or prime, respectively.
* Static methods isEven(int), isOdd(int), and isPrime(int) that return true if the specified value is even, odd, or prime, respectively.
* Static methods isEven(MyInteger), isOdd(MyInteger), and isPrime(MyInteger) that return true if the specified value is even, odd, or prime, respectively.
* Methods equals(int) and equals(MyInteger) that return true if the value in the 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.
