This is My Main Class:

static String instrument = null; static String choice = null; static Scanner input = new Scanner(System.in); static BrassFamily brass = new BrassFamily(instrument); static StringFamily string = new StringFamily(instrument); static WoodwindFamily woodwind = new WoodwindFamily(instrument); static PercussionFamily percussion = new PercussionFamily(instrument); //Begin Main Method @SuppressWarnings("empty-statement") public static void main(String[] args) {

int instrumentFam = 0;

System.out.println("Select one of the following instrument families: ");

System.out.println("1.Brass 2.String 3.Woodwind 4.Percussion " + "5.Display all instruments 6.Exit"); System.out.println("->: "); instrumentFam = input.nextInt();

switch (instrumentFam) { case 1:

int amount;

System.out.println("How many brass instruments would you like to enter? "); amount = input.nextInt();

String[] BrassNames = new String[amount];

for (int i = 0; i < amount; i++) { System.out.println("Enter instrument" + i); BrassNames[i] = input.next(); }

System.out.println("Display instruments? (Y for Yes, N for No)"); choice = input.next();

if (choice.equalsIgnoreCase("Y")) { for (int i = 0; i < amount; i++) { System.out.println(BrassNames[i]); } } else { System.out.println("Enter more instruments? "); } break; case 2: //String instruments

System.out.println("How many string instruments would you like to enter? "); amount = input.nextInt();

String[] StringNames = new String[amount];

for (int i = 0; i < amount; i++) { System.out.println("Enter instrument" + i); StringNames[i] = input.next(); }

System.out.println("Display instruments? (Y for Yes, N for No)"); choice = input.next();

if (choice.equalsIgnoreCase("Y")) { for (int i = 0; i < amount; i++) { System.out.println(StringNames[i]); } } else { System.out.println("Enter more instruments? "); } break; case 3: //Woodwind instruments

System.out.println("How many woodwind instruments would you like to enter? "); amount = input.nextInt();

String[] WoodwindNames = new String[amount];

for (int i = 0; i < amount; i++) { System.out.println("Enter instrument" + i); WoodwindNames[i] = input.next(); }

System.out.println("Display instruments? (Y for Yes, N for No)"); choice = input.next();

if (choice.equalsIgnoreCase("Y")) { for (int i = 1; i < amount; i++) { } } else { System.out.println("Enter more instruments? "); } break; case 4: //Percusssion instruments

System.out.println("Display instruments? (Y for Yes, N for No)"); choice = input.next();

if (choice.equalsIgnoreCase("Y")) { for (int i = 0; i < amount; i++) { System.out.println(PercussionNames[i]); } } else { System.out.println("Enter more instruments? "); } break; case 5://Display all instruments displayInstruments(); break; case 6://Exit Program GoodBye(); } } /** * Method GoodBye: used to say goodbye. Common for several calls */ private static void GoodBye() { System.out.print("Enter more instrucments? (Y for Yes, N for No)->: "); choice = input.next(); if (choice.equalsIgnoreCase("n")) { System.out.println("Goodbye"); System.exit(0); } } /** * Method displayInstruments: Used to display results */ private static void displayInstruments() {

brass.howToPlay(); string.howToPlay(); woodwind.howToPlay(); percussion.howToPlay();

} }//End Main Method

And this is the correct structure it's supposed to be in. Can someone jsut clean mine up I have been looking at it so long Im confusing myself & im having trouble on how to call the display and goodbye methods.
