what is the need of using interface in program
ex:if we have a program like this
interface1()
{
void method1();
void method();
}
class a1 : interface1
{
a1 b = new b();
b.method1();
b.method2();
}

In a program if multiple classes which has the some common
methods are used,then in that case we will use interfaces.
With the classes you wont left a method without definition
unless that is abstract.Interfaces will help us to provide
different implementations according to user needs.In
interface by default all methods are PUBLIC.But in class by
default it is private.
