given an NSDictionary theDictionary;
and doing this:

       Object a = new Object ();
       Object b = new Object ();
       theDictionary.setObjectForKey(a, b);

why does the java compiler give this error:

Classes/theController.java:324: cannot resolve symbol
symbol  : method setObjectForKey (java.lang.Object,java.lang.Object)


the objectForKey method works fine:


Integer sTag = (Integer) theDictionary.objectForKey("theKey");
