Question

NoteADT - Show the interface and all abstract methods

NoteDataStructureClass - Show the following methods: default constructor, overloaded constructor, copy constructor, setValue (calls other methods: setStrValue, setKeyColor, setFrequency), setLength (calls setStrLength), setFrequency (should be double value- cast)setKeyColor, getValue, getLength, getKeyColor, getFrequency, toString.

NoteClientDemoClass –Instantiate two Note objects using the overloaded constructor and two Note objects using the default constructor.

A sample output for 1 Note object might appear like:

Length: Eighth note

Value: -3

Black key (sharp)

369.995672 Hz

Expert Solution

Step 1

Algorithm:

Create an interface called "NoteADT" with the methods "setStrValue", "setKeyColor", "setFrequency", "setStrLength", "getFrequency", "getValue", "getKeyColor", "getLength", and "toString".
Implement the interface in a class called "NoteDataStructureClass".
Declare private variables letter, length, value, keyColor, and frequency in the "NoteDataStructureClass".
Define a default constructor that sets the default length to "quarter note" and letter to 'C'.
Define a parameterized constructor that sets the values of letter, length, keyColor, value, and frequency.
Define a copy constructor that creates a copy of the NoteDataStructureClass object.
Implement the methods in the interface by setting the values of the private variables.
Override the toString method to return a formatted string of the object's properties.
Create a class called "NoteClientDemoClass" with the main method.
Create four objects of the "NoteDataStructureClass" class, n1, n2, n3, and n4 using the default and parameterized constructors.
Use the setter methods to set the properties of n3 and n4 objects.
Print the objects using the toString method to display the properties of the NoteDataStructureClass objects.
