"extends" and "implements"

[newbie101]

does anyone know the difference between "extends" and "implements"?

[Tolls]

What did Google tell you?
Especially the pages from Oracle, where these things are defined?

[stchman]

The extends allows a class to inherit the methods from another class.

The implements allows a class to implement all the methods from an Interface. Remember an interface can only be implemented in a class.

The brief explanation above is good, but there is a lot more you cantons out by googling as tolls suggested.

Oh, and don't send IMs.
That sort of defeats the point of the forum as a resource of information.
