Is it intentional that the following code fragment:
Hashtable[] ht = new Hashtable[2];
System.out.println("Hashtable array = " + ht + ", ht[0] = " + ht[0]);
ht[0].put("foo", "bar");
produces the following output:
Hashtable array = class[2], ht[0] = <Null Object>
java.lang.NullPointerException
at ...
I would have expected that the Hashtable() contstructor would be run
automagically on each element of ht, but this was clearly not the
case. I'm running Alpha3 on an SS5 with Solaris 2.4.
Thanks.
