I think the answer is no, but is there any way for me to know how many
Objects reference a given Object?
The given object contains a reference to a disk file, and I'd like to
delete the file when there are no more threads that reference the

I have absolutely no idea how to do this. I inserted a [] array into a
vector, which then ofcourse became a [][] array, but now can't get it
out back to a Object[][].
Vector vector = new Vector();

Web-start offers file access even to *sandboxed*
applications, assumimg the user approves each file.
There is a checkbox when opening 'always allow'
that seems to have no effect (on Win XP, Java 1.5).

We would like to use a tool to spot methods in oour packages that are
not being used. We have the entire source set under Eclipse, so a
plugin would be best. We do not want anything too complex or a graph,
or statistics, just a simple report that indicates what methods are not

Tonight I started to structure all my classes using packages and after
getting all the 'package' and 'import' statements working properly I ran
into issues with the code that loads images (nullpointer exceptions).
They were all working prior to the package changeover.

I saw a UML diagram showing two classes A and B. A "has a" B in it. B
"has a" A in it. I feel hard to understand.
Could you help me or give me some code to show that concept?
Thank you very much.

I want to write a command line java client program. And the program

Unless I'm mistaken, there is no SDK implementation for a List of
unique elements. All List implementations accept duplicates; Set
implementations do not. However, having a List of unique elements is a
useful object.

I store in TreeSet expressions in some natural language. This can be
any natural language. The content of a set is sorted in this language
by language collator:
collator = Collator.getInstance(locale);

I have a form that the user enters information into. This information
is then passed to a servlet for processing. The problem is the form
doesnt seem to pass strings of more than one word . eg. if I put in

I have a jsp jstl question.  It is actually kind of simple, but I still
couldnt get an answer.  And it is more of a design question.
