Modifying the Code

Is there any easy way to modify the code so we don't have the common bug listing one song as songs as Craig pointed out in the video? Here's what I have, but I'm sure there is a much easier way to access the count. Any ideas?

if (songBook.getSongCount() == 1) { System.out.printf("There is %d song. %n", songBook.getSongCount()); } else { System.out.printf("There are %d songs. %n", songBook.getSongCount()); }

Hi Michael, your approach is fine, except some redundant code.

Since we already established that there is 1 song in the first condition, then there is no need to call the method again just for printing results, so:

if (songBook.getSongCount()== 1) {
    System.out.println("There is 1 song. %n"); 
}

cheers

lol, I didn't even think of that. You get so used to calling methods all the time, it didn't even occur to me I didn't need a placeholder there. Thanks deckey!
