Can't compie code from the API examples

Hi

I'm trying to compile the following code, copied from the API (1.5.0)*:

Hashtable numbers = new Hashtable();
numbers.put("one", new Integer(1));
numbers.put("two", new Integer(2));
numbers.put("three", new Integer(3));

And I get the following error messages:

C:\KTH\algoritmer\HashtableTest.java:13: <identifier> expected
numbers.put("one", new Integer(1));
^
C:\KTH\algoritmer\HashtableTest.java:14: <identifier> expected
numbers.put("two", new Integer(2));
^
C:\KTH\algoritmer\HashtableTest.java:15: <identifier> expected
numbers.put("three", new Integer(3));
^

The way I understand it, Hashtable is generic (or whatever it's called) in
1.5, since it says Class Hashtable<K,V>.
But then how do I use Hashtable? The example code doesn't work. Or am I
doing something else wrong?

You tried to compile this, as shown, copied directly from the online
example? Did you wrap it in a class? Did you import anything? Where is the
rest of your code?

We can't tell. Post a complete, short example program that includes the
above snippet, so we can see it in context.

I'm terribly sorry. My misstake. Sure I imported everything needed and
wrapped it in a class, but I forgot to wrap it in a method aswell... duh...
hmm, I blame the late hour (1.30am). sorry!
everything works now.
