Java 适配器模式：解决 Windows Media Player 与 RealPlayer 兼容难题并支持未来扩展

以下是一个使用适配器模式来处理媒体播放器兼容问题的 Java 示例代码： ```java interface MediaPlayer { void play(); void stop(); } class WindowsMediaPlayerAdapter implements MediaPlayer { private WindowsMediaPlayer windowsMediaPlayer; WindowsMediaPlayerAdapter(WindowsMediaPlayer windowsMediaPlayer) { this.windowsMediaPlayer = windowsMediaPlayer; } @Override public void play() { windowsMediaPlayer.bofang(); } @Override public void stop() { windowsMediaPlayer.tingzhi(); } } class WindowsMediaPlayer { public void bofang() { System.out.println("Windows Media Player is playing"); } public void tingzhi() { System.out.println("Windows Media Player is stopped"); } } class RealPlayerAdapter implements MediaPlayer { private RealPlayer realPlayer; RealPlayerAdapter(RealPlayer realPlayer) { this.realPlayer = realPlayer; } @Override public void play() { realPlayer.play(); } @Override public void stop() { realPlayer.stop(); } } class RealPlayer { public void play() { System.out.println("RealPlayer is playing"); } public void stop() { System.out.println("RealPlayer is stopped"); } } public class MediaPlayerAdapterExample { public static void main(String[] args) { WindowsMediaPlayer windowsMediaPlayer = new WindowsMediaPlayer(); MediaPlayer windowsAdapter = new WindowsMediaPlayerAdapter(windowsMediaPlayer); windowsAdapter.play(); windowsAdapter.stop(); RealPlayer realPlayer = new RealPlayer(); MediaPlayer realAdapter = new RealPlayerAdapter(realPlayer); realAdapter.play(); realAdapter.stop(); } } ``` 在上述代码中： - 定义了一个`MediaPlayer`接口，规定了通用的`play`和`stop`方法。 - 分别为`WindowsMediaPlayer`和`RealPlayer`创建了适配器类`WindowsMediaPlayerAdapter`和`RealPlayerAdapter`，将它们各自独特的方法适配到`MediaPlayer`接口的方法。 这样，在应用程序中可以通过`MediaPlayer`接口来操作不同的播放器，并且如果将来添加新的媒体播放器，只需创建新的适配器类来实现`MediaPlayer`接口即可。 ######[AI写代码神器 | 554点数解答 | 2024-11-14 17:15:33]
