	`4`	`+ * An Adapter pattern acts as a connector between two incompatible interfaces that otherwise cannot be connected`

	`6`	`+ * interface.`

	`8`	`+ * The main motive behind using this pattern is to convert an existing interface into another interface that the client`
	`9`	`+ * expects. It’s usually implemented once the application is designed.`
