Object Oriented Programming Project-Java project Music Player Application Student Information
Name: DANIEL NYERERE AND CHIELMELIE OKEKE Student ID: 20220869 , 20220937
Project Overview This is a Java application that simulates a music player with a graphical user interface. The application allows users to manage a library of songs, create and manage playlists, and control the playback of songs with features like:
Play, pause, stop functionality Previous and next track buttons for playlist navigation Volume control Progress bar with seek functionality Library management Playlist creation and management
Object-Oriented Programming Principles Demonstrated This project demonstrates several key OOP principles:
Encapsulation:
Private attributes with public getter methods Proper data hiding and access control
Association:
Relationship between MusicPlayer, Playlist, and Song classes Clear separation of responsibilities
Collection Management:
Managing lists of songs in the library and playlists Using appropriate data structures (ArrayList, HashMap)
MVC Pattern:
Model: Song, Playlist, MusicPlayer classes View: MusicPlayerGUI Controller: MusicPlayerApp and event handlers
Getting Started Prerequisites
Java Development Kit (JDK) 8 or higher Audio files in WAV format for playback
Compilation and Running
Compile all the Java files: javac -d bin com/musicplayer/model/.java com/musicplayer/player/.java com/musicplayer/gui/.java com/musicplayer/main/.java
Run the application: java -cp bin com.musicplayer.main.MusicPlayerApp
Using the Application Adding Songs: Click the "Add Song" button Browse for audio files Enter song details (title, artist, genre) Creating Playlists: Click the "Create Playlist" button Enter a name for the playlist Adding Songs to Playlists: Select a song from the library Select a playlist from the dropdown Click "Add to Playlist"
Playing Songs:
Double-click on a song in the library or playlist Use the control buttons (play, pause, stop) Adjust volume using the volume slider Navigate through the song using the progress bar
Playlist Navigation:
Use the previous and next buttons to navigate through songs in a playlist

Extensions and Enhancements This implementation extends the basic requirements by adding:
A full graphical user interface Real audio playback capability using Java Sound API Progress bar with seek functionality Volume control Playlist navigation with previous/next buttons Double-click to play functionality File browser for adding songs Visual feedback during playback
Troubleshooting
No Sound: Ensure your audio files are in WAV, MP3, or AIFF format File Not Found: Check the file paths of your audio files Unsupported Audio Format: The Java Sound API has limited support for certain audio formats
