Interface

  • An interface is similar to a class except that it cannot contain code.
  • An interface can define method names and arguments, but not the contents of the methods.
  • Any classes implementing an interface must implement all methods defined by the interface.
  • A class can implement multiple interfaces.
  • An interface is declared using the "interface" keyword.
  • Interfaces can't maintain Non-abstract methods.
