Create a shuffle method using the below pseudo code as a guide:
create a new empty arraylist (called newList)
while <there are still songs left>
randomly select the index of one song on the playlist
remove it from the current playlist and
place it at the end of newList
songs = newList
Hint: Generate a random number using the Random class in the Java library. Its method is:
public int nextInt(int n).
This returns a pseudorandom, uniformly distributed int value as low as 0 and as high as n. Therefore, nextInt(songs.size()) gives you a random index. Remember that the size of songs lessens by one each time you add a randomly selected song to newList. You will need to account for this each time you generate a random number.
