Declare an interface called Incrementable which represents items that store an integer that can be incremented in some way. The interface has a method called increment that increments the value and a method called getValue that returns the value. Once you have written the interface, write two classes called SequentialIncrementer and RandomIncrementer that implement the interface. The SequentialIncrementer begins its value at 0 and increases it by 1 each time it is incremented. The RandomIncrementer begins its value at a random integer and changes it to a new random integer each time it is incremented.
