Create an interface MessageDecoder that has a single abstract method decode(cipherText), where cipherText is the message to be decoded.The method will returnthe decoded message.
Create a class SubstitutionCipher that implements the interface MessageDecoder as described above. The constructorshould have one parameter called shift. Define the method decode so that each letter is shifted by the value in the shif. For example, if shift is 3, a will be replaced by d, b will be replaced bt e, c will be replaced by f, and so on. Hint: You may wish to define a private methodthat shifts a single character.
Create a class ShuffleCipher that implements the interface MessageDecoder. The constructor should haveone parameter called n. Define the method decode so that the message is shuffledn times.To perform one shuffle, split the message in half and then take the charactersfrom each half alternatively. For example, if the messsage is "abcdefghi", the halves are "abcde" and "fghi". The shuffled…

Create an interface that shall have 2 methods and one string type attribute, also create an implementation class of the interface that shall define both methods (you can print YOUR favorite quote in each method body).
Modify the GeometricObject class to implement the Comparable interface and define a static max
method in the GeometricObject class for finding the larger of two GeometricObject objects. Draw
the UML diagram and implement the new GeometricObject class. Write a test program that uses
the max method to find the larger of two circles, the larger of two rectangles.using java programming
