I have been working on a homework assignment involving different aspects of a guitar.

• A private int data field named numStrings that defines the number of strings on the guitar. The default value should be 6.




• A private double data field named guitarLength that defines the length of the guitar in inches. The default value should be 28.2

-A private String data field named guitarManufacturer that defines the manufacturer of the guitar. The default value should be “Gibson”.

-A private Color data field named guitarColor that defines the color of the guitar. The default value should be Color.Red.

• A no argument constructor that creates a Guitar using the default number of strings, length, manufacturer and color.
  -A constructor that creates a Guitar using a specified number of strings, length, manufacturer and color.

-Getter methods for all data fields.

-A playGuitar() method that returns a string representation of 16 randomly selected musical notes of random duration. For example, the first part of the string returned might look like this: [A(2), G(3), B(0.5), C(1), C(1), D(0.25), …]. You can assume one octave in the key of C where valid notes include A, B, C, D, E, F and G and duration values are .25, .5, 1, 2, and 4 representing sixteenth notes, eighth notes, quarter notes, half notes and whole notes, respectively.

-A toString() method that displays the number of strings, length, manufacturer and color in String format.

Here is my code so far, but when I compile it through javac, I get an error at the very end of the program because of "public class TestGuitar"
