1 Abstract classes can have methods with implementation whereas interface provides absolute abstraction and canât have any method implementations. 2  Abstract classes can have constructors but interfaces canât have constructors. 3  Abstract class have all the features of a normal java class except that we canât instantiate it.
An interface can contain declarations for functions, events, and properties. All interface members have public accessibility. An interface can also contain static data members, functions, events, and properties, and these static members must be defined in the interface. An interface defines how a class may be implemented. An interface is not a class and classes can only implement interfaces. When a class defines a function declared in an interface, the function is implemented, not overridden. Therefore, name lookup does not include interface members. A class or struct that derives from an interface must implement all members of the interface.
