This question is regarding a homework project in my first Java programming class (online program).The assignment is to create a stringed instrument class using (among other things) an array of String names representing instrument string names (A, E, etc).  The idea for the 12-string is beyond the scope of the assignment (it doesn't have to be included at all) but now that I've thought of it, I want to figure out how to make it work.Part of me feels like the 12-String should have its own class, but another part of me feels that it should be in the guitar class because it's a guitar.  I suppose this will become clear as I progress but I thought I would see what kind of response I get here.Also, why would they ask for a String[] for the instrument string names?  Seems like a char[] makes more sense.Thank you for any insight.Here's my code so far (it's a work in progress):public class Guitar {private int numberOfStrings = 6;private static int numberOfGuitars = 0;private String[] stringNotes = {E, A, D, G, B, A};private boolean tuned = false;private boolean playing = false;public Guitar(){    numberOfGuitars++;}public Guitar(boolean twelveString){    if(twelveString){        stringNotes[0] = E, E;        stringNotes[1] = A, A;        stringNotes[2] = D, D;        stringNotes[3] = G, G;        stringNotes[4] = B, B;        stringNotes[5] = E, E;        numberOfStrings = 12;    }}public int getNumberOfStrings() {    return numberOfStrings;}public void setNumberOfStrings(int strings) {    if(strings == 12 || strings == 6) {        if(strings == 12){            stringNotes[0] = E, E;            stringNotes[1] = A, A;            stringNotes[2] = D, D;            stringNotes[3] = G, G;            stringNotes[4] = B, B;            stringNotes[5] = E, E;            numberOfStrings = strings;        }        if(strings == 6)            numberOfStrings = strings;    }//if    else        System.out.println(***ERROR***Guitar can only have 6 or 12 strings***ERROR***);}public void getStringNotes() {        for(int i = 0; i < stringNotes.length; i++){            if(i == stringNotes.length - 1)                System.out.println(stringNotes[i]);            else                System.out.print(stringNotes[i] + , );        }//for}
Should the 12-String be in its own class and why?
