Name:DANIEL NYERERE 20220869 AND CHIELMELIE OKEKE 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
• Volume control
• Progress bar with playback tracking
• Library management
• Playlist creation and management

Object-Oriented Programming Principles Demonstrated

🔹 Encapsulation

• Private attributes with public getter methods
• Proper data hiding and access control

🔹 Association

• Relationships between MusicPlayer, Playlist, and Song classes
• Clear separation of responsibilities

🔹 Collection Management

• Managing lists of songs in the library and playlists
• Use of ArrayList and HashMap for dynamic data handling

🔹 MVC Pattern

• Model:Song, Playlist, MusicPlayer
• View: MusicPlayerView (Swing GUI)
• Controller: MusicPlayerController (handles user interaction and playback logic)

Prerequisites

• Java Development Kit (JDK) 8 or higher
• Audio files in WAV format for playback
