The program is for randomising a given playlist according to the conditions given.

Question

The program should then generate a random playlist of the songs given as input, according to the following constraints:

1. An artiste cannot have more than two songs in a row (so no “triple play”, as the radio DJs might say);
2. An artiste cannot have more than three songs in total in the playlist;
3. A song cannot appear twice in the playlist;
4. The total playlist length should be as close as possible to one hour. Specifically, the last song must start on or before 59:59.
5. The randomised playlist and the total time should be printed out in the following format:

Randomised playlist

Artiste name: "Song title" (Song duration)

Artiste name: "Song title" (Song duration)

...

Artiste name: "Song title" (Song duration)

Total duration: <Total duration>.

An example randomised playlist would be the following:

Randomised playlist

Public Service Broadcasting: "They Gave Me A Lamp" (3:56)

The War on Drugs: "Under the Pressure" (8:51)

Future Islands: "Spirit" (4:22)

Arcade Fire: "Cold Wind" (3:12)

The National: "England" (5:40)

Bon Iver: "re: Stacks" (6:40)

Sufjan Stevens: "Chicago [To String Remix]" (5:32)

Jos Gonzlez: "Heartbeats" (2:40)

Public Service Broadcasting: "The Other Side" (6:20)

Public Service Broadcasting: "Go!" (4:13)

Arcade Fire: "Rebellion (Lies)" (5:10)

London Grammar: "Wasting My Young Years" (3:24)

Total duration: 60:00.

Answer 1

I have uploaded the source code in the RESOURCES section whose description is THIS LINK!!

The source code is about 500 lines long not counting the input file and too big to fit here.

There are actually 4 (FOUR) files:

SongRec.java <--- class for a single song: title, artist, time

SongLIst.java <-- contains the final playlist

Jukebox.java <--- stores the array of songs

JukeboxSongMain.java <--- driver and helper modules

songs.dat is the input file

You had better download it while you can, because they will be CLOSING the FILES section

in the RESOURCES.

Otherwise you will have to email me, or give me write permission to your google drive

and pass me the link.
