Q)What is the realtime usage of an interface in Java
    => "coding to interfaces is superior to coding to classes"
    =>interfaces fecilitate loose coupling between service requestor
    and service provider.
      For eg.  Java applications use interfaces in JDBC (A Java based data access technology    )   
                  to communicate with the database. These interfaces provide
		  JDBC driver vendor independency in Java projects.
		  
             =>Similarly, Servlet interfaces provide Web container vendor independency
Q)Does java support multiple intheritance?
  =>No.
  =>We have 2 types of multiple inheritance.
             1)Declarative multiple inheritance(interface)
	     2)implementation multiple inheritance(class)
=>Java supports declarative multiple inheritance.
