Interfaces

Interface is a model of a class.

Interface contains list of properties and methods, that are to be implemented in a class.

Class implements the interface and provides definition for interface methods.

{

property : datatype;

method( ) : returntype;

}

Child Class

class classname implements interfacename

{

property : datatype;

method( ) : returntype

{

}

}

var variable: classname;
