When I write these instructions in a Processing Class (also in the setup function)
-----------------------
  TreeMap<Integer,String> tMap = new TreeMap<Integer,String>();
 
  tMap.put(1,"A");
  tMap.put(2,"B");
  tMap.put(3,"C");
  Set<Map.Entry<Integer,String>> set = tMap.entrySet();
-----------------------
the program says to me

  /* Syntax error on token "<",TypeArgumentList2 expected after this token */


When I do the same thing in Eclipse
-----------------------
import java.util.*;
public class MapColl {

    /**
     * @param args
     */
    public static void main(String[] args) {
       
        TreeMap<Integer,String> tMap = new TreeMap<Integer,String>();
         
          tMap.put(1,"A");
          tMap.put(2,"B");
          tMap.put(3,"C");
          Set<Map.Entry<Integer,String>> set = tMap.entrySet();
          for (Map.Entry<Integer,String> o : set){ 
                
                System.out.print(o.getKey() + " : " );
                System.out.println(o.getValue()); 
              }        
    }
}

-----------------------

everything is ok. Why ??

Thanks for any help
