pure abstract class and interface
<p>Can anyone tell me what exactly the difference between an completely abstract class and an interface?</p>

<p>An Abstract class can also have all its methods as abstract. An interface has all its methods as abstract. What is the main difference between the two in this scenario?</p>

<p>If there is difference between a pure abstract Class and interface? What is the use of interface? Where interface is being used we can make use of pure abstract class? </p>
