Adapter Pattern Adapter pattern works as a bridge between two incompatible interfaces. This type of design pattern comes under structural pattern as this pattern combines the capability of two independent interfaces This pattern involves a single class which is responsible to join functionalities of independent or incompatible interfaces, A real life example could be a case of card reader which acts as an adapter between memory card and a laptop. You plugins the memory card into card reader and card reader into the laptop so that memory card can be read via laptop We are demonstrating use of Adapter pattern via following example in which an audio player device can play mp3 files only and wants to use an advanced audio player capable of playing vic and mp4 files. Implementation We've an interface Media Player interface and a concrete class Audio Player implementing the Media Player interface. Audio Player can play mp3 format audio files by default We're having another interface Advanced Media Player and concrete classes implementing the Advanced Media Player interface. These classes can play vic and mp4 format files We want to make Audio Player to play other formats as well. To attain this, we've created an adapter class MediaAdapter which implements the Media Player interface and uses Advanced Media Player objects to play the required format. Audio Player uses the adapter class MediaAdapter passing it the desired audio type without knowing the actual class which can play the desired format. AdapterPatternDemo, our demo class will use Audio Player class to play various formats.
