2. 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 3 1 1 -9 7 5 4 -2 0 2 Write a complete Java program. The default constructor should set a note to a middle C guarter 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 your - - a) The letter of the note (A, B, C, 6) 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.te calculate the frequency, use the formula: 440 2/12 where n is the note number
