Answer:

Explanation:

Using the main() and Instrument class which can be found online. We can create the following StringInstrument class that extends the Instrument class itself. The only seperate variables that the StringInstrument class posses' would be the number of Strings (numStrings) and the number of frets (numFrets). Due to technical difficulties I have added the code as a seperate text file below.
