遍历hashtable的方法
如果想了解更多，请查询JDK帮助。
Hashtable ht = new Hashtable();
ht.put( " one " , new Integer( 1 ));
ht.put( " two " , new Integer( 2 ));
Enumeration en = ht.elements();
while (en.hasMoreElements()){
System. out .println((Integer)en.nextElement());
}
or
Hashtable ht = new Hashtable();
ht.put( " one " , new Integer( 1 ));
ht.put( " two " , new Integer( 2 ));
Iterator it = hr.keySet().Iterator();
while (it.hasNext()){
System. out .println(hr. get (it.next()));
}
or
Set s = ht.entrySet();
for (Object o:s.toArray()){
System. out .println(o);
}
// only java 5.0
// print one=1 two=2
}
