Radio station KJAVA wants a class to keep track of recordings it plays. Create a class named Recording that contains fields to hold methods for setting and getting a Recording’s title, artist, and playing time in seconds.

Write an application that instantiates five Recording objects and prompts the user for values for the data fields. Then prompt the user to enter which field the Recordings should be sorted by—(S)ong title, (A)rtist, or playing (T)ime. Perform the requested sort procedure, and display the Recording objects.

Given classes:

public class Recording {

privateString song;

privateString artist;

privateint playTime;

publicvoidsetSong(Stringtitle) {

}

publicvoidsetArtist(Stringname) {

}

publicvoidsetPlayTime(inttime) {

}

publicStringgetSong() {

}

publicStringgetArtist() {

}

publicintgetPlayTime() {

}

import java.util.*;

public class RecordingSort {

publicstaticvoidmain(String[] args) {

// Write your code here
