Question

This is the question -

Below are the lyrics for the song “The Twelve Days of Christmas.” The song contains a list of gifts received for the holiday. The list is cumulative so that as each “day” passes, a new verse contains all the words of the previous verse, plus a new item.

On the 12th day of Christmas My true love gave to me Twelve drummers drumming Eleven pipers piping Ten lords a-leaping Nine ladies dancing Eight maids a-milking Seven swans a-swimming Six geese a-laying Five golden rings Four calling birds Three French hens Two turtle doves and A partridge in a pear tree

Write an application that displays the words to the song starting with any day the user enters. (Hint: Use a switch statement with cases in descending day order and without any break statements so that the lyrics for any day repeat all the lyrics for previous days.)

This is the code I have but the program doesn't like it -

import java.util.*;

public class TwelveDays {

Scanner input = new Scanner(System.in);

public static void main (String args[]) {

int day=getChoice();

//My true love gave to me is common part in the song

//song should start with that part

String song="My true love gave to me";

switch(day){

case 12:song+=" Twelve drummers drumming";

case 11:song+=" Eleven pipers piping";

case 10:song+=" Ten lords a-leaping";

case 9:song+=" Nine ladies dancing";

case 8:song+=" Eight maids a-milking";

case 7:song+=" Seven swans a-swimming";

case 6:song+=" Six geese a-laying";

case 5:song+=" Five golden rings";

case 4:song+=" Four calling birds";

case 3:song+=" Three French hens";

case 2:song+=" Two turtle doves";

case 1:song+=" and A partridge in a pear tree";

break;

default:song="NOT A VALID DAY";

}

System.out.println(song);

}

public static int getChoice() {

Scanner input = new Scanner(System.in);

System.out.println("Enter a day from 1 to 12: ");

day = input.nextInt();

return day;

}
