We cannot define constructor of super class in subclass because the order of execution of constructors will be from super class to current class. So there is no need of defining the super class constructor in subclass.

One of the "clean" features of the Java programming language is that it mandates a separation between interfaces (pure behavior) and classes (state and behavior). Interfaces are used in Java to specify the behavior of derived classes. Often you will come across interfaces in Java that have no behavior. In other words, they are just empty interface definitions. These are known as marker interfaces....
