In this exercise, you are going to build a hierarchy to create instrument objects. We are going to create part of the orchestra using three classes, Instrument, Wind, and Strings. Note that the Strings class has a name very close to the String class, so be careful with your naming convention! We need to save the following characteristics: Name and family should be saved for all instruments We need to specify whether a strings instrument uses a bow We need to specify whether a wind instrument uses a reed Build the classes out with getters and setters for all classes. Only the superclass needs a toString and the toString should print like this: Violin is a member of the Strings family. Your constructors should be set up to match the objects created in the InstrumentTester class.
These are the files given
public class InstrumentTester
{
public static void main(String[] args)
{
/**
* Don't Change This Tester Class!
*
* When you are finished, this should run without error.

Wind tuba = new Wind("Tuba", "Brass", false);
Wind clarinet = new Wind("Clarinet", "Woodwind", true);
Strings violin = new Strings("Violin", true);

System.out.println(tuba);
System.out.println(clarinet);
System.out.println(violin);
System.out.println(harp);
