I don't know if these problems arise from a misunderstanding on my part, or if
it's a problem with Eclipse.  Everything that I have been able to find indicates
that I'm on the right track.  The code is at the end of the report.

1. I've implemented a Map, and I'm having problems with the #entrySet method. 
The message I get (from Eclipse) is: "Type mismatch: Cannot convert from
Set<Map<K,V>.Entry<String, V> to Set<Map.Entry<String, V>>"  (javac has no problem)

2. Javac 1.5.0-beta2 complains "GenericMap.java:7: test.GenericMap is not
abstract and does not override abstract method putAll(java.util.Map<? extends
java.lang.String,? extends V>) in java.util.Map
public class GenericMap<V> implements Map<String, V> {"  while Eclipse accepts
the class.


package test;

import java.util.Collection;
import java.util.Map;
import java.util.Set;

public class GenericMap<V> implements Map<String, V> {
   private Map<String, V> backingMap;
   
   public int size() { return 0; }

   public boolean isEmpty() { return false; }

   public boolean containsKey(Object key) { return false; }

   public boolean containsValue(Object value) { return false; }

   public V get(Object key) { return null; }

   public V put(String key, V value) { return null; }

   public V remove(Object key) { return null; }

   public void clear() { }

   public Set<String> keySet() { return null; }

   public Collection<V> values() { return null; }


   public void putAll(Map<String, ? extends V> t) { }

  
   public Set<Map.Entry<String, V>> entrySet() {
      return this.backingMap.entrySet();
   }
}
