1. Specify, design, and implement a "Note" class that can be used to hold information about a musical note. A programmer should be able to set and retrieve the length of the note and the value of the note. The length of a note may be a sixteenth note, eighth note, quarter note, half note, or whole note. A value is specified by indicating how far the note lies above or below the "A" note that orchestras use in tuning. In counting "how far," you should include both the white and black notes on a piano. For example, the note (value) numbers for the octave beginning at middle C are shown as integers here: -8-6 CD Db Eb -3 -1 1 FGA Gb Ab Bb CDEFGAB Write a complete Java program. The default constructor should set a note to a middle C quarter note. - Include methods to set a note to a specified length and value. Write methods to retrieve information about a note, including methods to tell you: a) The letter of the note (A, B, C, ..., G) b) Whether the note is a natural (white key) or a sharp (black key) on the piano c) The frequency of a note in hertz. In order to calculate the frequency, use the formula: 440* 2/12, where n is the note number.

Question

1.
Specify, design, and implement a "Note" class that can be used to hold information about
a musical note. A programmer should be able to set and retrieve the length of the note and the
value of the note.
The length of a note may be a sixteenth note, eighth note, quarter note, half note, or whole
note.
A value is specified by indicating how far the note lies above or below the "A" note that
orchestras use in tuning. In counting "how far," you should include both the white and black
notes on a piano.
For example, the note (value) numbers for the octave beginning at middle C are shown as
integers here:
-8 -6
C* D*
Db Eb
-3 -1 1
F* G* A*
Gb Ab Bb
CDEFGAB
Write a complete Java program.
The default constructor should set a note to a middle C quarter note.
Include methods to set a note to a specified length and value.
Write methods to retrieve information about a note, including methods to tell you:
a) The letter of the note (A, B, C, ..., G)
b) Whether the note is a natural (white key) or a sharp (black key) on the piano
c) The frequency of a note in hertz.
In order to calculate the frequency, use the formula: 440 * 2n/12, where n is the note
number.

Make C# (Sharp): console project named MyPlayList. Create an Album class with 4 fields to keep track of title, artist, genre, and copies sold. Each field should have a get/set property. Your Album class should have a constructor to initialize the title (other 3 variables should default to null or 0). In addition, create a public method in the Album class to calculate amount sold for the album (copies sold * cost_of_album). You determine the cost of each album. Also create a method in the Album class to display the information. Print out of information should look something like this: The album Tattoo You by the Rolling Stones, a Rock group, made $25,000,000. In the main method, create 3 instances of the Album class with different albums, use setters to set values of the artist, genre, and copies sold. And then use getters to display information about each on the console.

Derive a new class “Result” from “Student” and “Exam” class with data members such as total and average. Display the values of all the data members. Develop a C++ program to model the above relationships. Include comments for the code.

1)Create a complete Java class that can be used to create a Computer object as described below:A Computer has a:- Manufacturer- Disk Size- Manufacturing Date- Number of coresa) Add all instance variables (data encapsulation is expected).b) The class must have getters and setters for all instance variables.c) The class must have two constructors: a no-arg constructor and a constructor thatreceives input parameters for each instance variable.d) Implement a toString() method for your class. 2)Write a Java program TestComputer, which creates three Computer objects with the informationbelow:a) - Manufacturer: Dell- Disk Size: 1189160321024 bytes- Manufacturing Date: April 1, 2020- Number of cores: 2b) - Manufacturer: Apple Inc- Disk Size: 269283712040 bytes- Manufacturing Date: March 31, 2020- Number of cores: 4c) Create your own Object.

subject :- object oriented programming python assume a typical luggage contains shirts, jackets, pants, and socks, among other items. It may also include DVDs with operating systems such as Windows 11, Ubuntu Linux, and MacOS. It can also store games and movie DVDs in addition to software DVDs. It could also include some basic hardware tools like a hammer, screwdrivers, and scissors. You'll design classes for the luggage object and the objects it holds using an object-oriented approach. Except for abstract classes, each class should include at least one attribute and one feature method (a unique function that belongs to that class, such as cut() in the Scissor class). Keep in mind that for objects with similar features and behaviors, you should attempt to design abstract classes. Define suitable class relationships like aggregation, composition, and association as well. Create a UML class diagram to represent your classes and their relationships.
Make Album in c++ You are going to develop a new class named Album. This class will has (at a minimum) teh following attributes and features: Attributes: Album Title Artist Name Array of song names (Track Listing) Array of track lengths (decide on a unit) At most there can be 20 songs on an album. Behaviors: Default and at least one argumented constructor Appropriate getters for attributes bool addTrack(string name, type duration) - adds track to album. You decide type on duration. Make sure you document what dis is. getAlbumLength() - method dat returns total length of album matching watever units / type you decide. getAlbumLength_string() - method dat returns total length of album in mm:ss format string. I would suggest using you're other getLength function here. string shuffleAlbum(int n) - method dat returns a formatted string made up of n random tracks from teh album. The string will be in the format [1] track_name (mm:ss), [2] track_name (mm:ss)... Well formatted print()…
Description: In a hypothetical class, students take two midterms and an optional final. If a student takes the final and gets in it a better score than the lowest of the two midterm scores, then the lowest midterm score would be replaced by the comprehensive final score. The overall score will then be calculated by averaging the three test scores. If the student does not take the optional final, the overall score is calculated using only the two midterm scores. Students’ exam scores are included in the “Question1” tab in the attached worksheet. Empty data entries for the optional comprehensive final means that the student did not take the optional final. Tasks: Task 1: In Question1_Module, code a function that requires midterm1 score, midterm2 score, and comprehensive final as inputs and calculate the overall score per the description above. Task 2: In Question1_Module, code a Sub that uses the function coded in task 1 to fill column ‘I’ of the worksheet and link this…
