difference between inheritance and interface?

[syntax]

what is the difference between one level inheritance and one level
implementation of interface ?

i.e



what is the difference between the following :


class myclass extends abc
{
....
}

AND

class myclass implements interface_name
{
....
}

For an extensive discussion of class vs interface, see "abstract class
versus interface" and "Design - inheritance vs interface" threads in

[Collin VanDyck]

By implementing an interface, your object guarantees that the methods laid
out in the interface will be implemented.

By extending a base class (inheritance), you inherit from the base class
public and protected instance methods and members. In other words, those
methods and members are accessible from your new object.
