Given main() and the Instrument class, define a derived class, string Instrument, with methods to set and get private fields of the following types: • int to store the number of strings • int to store the number of frets boolean to store whether the instrument is bowed Ex. If the input is: Drums Zildjian 2015 2500 Guitar Gibson 2002 1200 6 19 false the output is: Instrument Information: Name: Drums Manufacturer: Zildjian Year built: 2015 Cost: 2500 Instrument Information: Name: Guitar Manufacturer: Gibson Year built: 2002 Cost: 1200 Number of strings: 6 Number of frets: 19 Is bowed: false
I need help with this Java problem as described in the image:
import java.util.Scanner;
public class InstrumentInformation {
   public static void main(String[] args) {
      Scanner scnr = new Scanner(System.in);
      Instrument myInstrument = new Instrument();
      StringInstrument myStringInstrument = new StringInstrument();
      String instrumentName, manufacturerName, stringInstrumentName, stringManufacturer;
      int yearBuilt, cost, stringYearBuilt, stringCost, numStrings, numFrets;
      boolean bowed;
      instrumentName = scnr.nextLine();
      manufacturerName = scnr.nextLine();
      yearBuilt = scnr.nextInt();
      scnr.nextLine();
      cost = scnr.nextInt();
      scnr.nextLine();
      stringInstrumentName = scnr.nextLine();
      stringManufacturer = scnr.nextLine();
      stringYearBuilt = scnr.nextInt();
      stringCost = scnr.nextInt();
      numStrings = scnr.nextInt();
      numFrets = scnr.nextInt();
      bowed = scnr.nextBoolean();
      myInstrument.setName(instrumentName);
      myInstrument.setManufacturer(manufacturerName);
      myInstrument.setYearBuilt(yearBuilt);
      myInstrument.setCost(cost);
      myInstrument.printInfo();
      myStringInstrument.setName(stringInstrumentName);
      myStringInstrument.setManufacturer(stringManufacturer);
      myStringInstrument.setYearBuilt(stringYearBuilt);
      myStringInstrument.setCost(stringCost);
      myStringInstrument.setNumOfStrings(numStrings);
      myStringInstrument.setNumOfFrets(numFrets);
      myStringInstrument.setIsBowed(bowed);
      myStringInstrument.printInfo();
      System.out.println("   Number of strings: " + myStringInstrument.getNumOfStrings());
      System.out.println("   Number of frets: " + myStringInstrument.getNumOfFrets());
      System.out.println("   Is bowed: " + myStringInstrument.getIsBowed());
   }
}
