Compiler thinks equals(Object) is abstract

Name: skT88420 Date: 09/25/99


Compiling this file results in 1 error saying equals (Object) is abstract.
Clue: equals(Object) is declared in interface Collection.
However, if you change "extends AbstractCollection" to
"implements Collection" bug does not occur.

import java.util.*;

public abstract class AbstractTypedSet
extends AbstractCollection
{
  public boolean eqData (Object x) {
   return super.equals (x);
  }
}
