去下个JAVA API看看,里面有
Hashtable hash = new Hashtable();
hash.put("first", new Integer(1));
hash.add("second", "Hello world!");
System.out.println(hash.get("first"));
System.out.println(hash.get("second"));
Hashtable hash = new Hashtable();
hash.put("first", new Integer(1));
hash.add("second", "Hello world!");
System.out.println(hash.get("first"));
System.out.println(hash.get("second"));
