Why final ?

I've been having some trouble with generic methods and inheritance.
Suppose I have an interface that looks like:
interface A {
 public <T extends MyClass> void foo(T input);

An interface forces the implementor to write the code for all the
(abstract) methods. Fine. But can I also enforce a specific
constructor footprint?
Maybe it sounds silly, but it isn't: I am constructing objects using

Can you pass arguments to Jar executables files like you can with with Java
class files at the command line?

I am in a discussion at work wether to implement an application server or not when using
java in a GNU/Linux environment.
The apps that are supposed to be written in java will reveice transactions from a socket and
depending on the transaction it will do some logic ...

I teach Java, and we're switching to 1.5.0 next semester.  I was thinking
about using the Scanner class to read data from text files, but I'm having
a problem specifying a delimiter string.
The file I'm using for the following example contains two records:

My Java application has a splash screen which was inspired on the ones
that are displayed when the Adobe programs (Photoshop, Illustrator,
InDesign) start up.
There is an outside invisible rectangle and some features that pretent

I wrote a simple http server using java.nio. I've run into a problem
where occasionally, calling close() on the SocketChannel closes the

I have this error "No enclosing instance of type ... is available due to

printable interface you would have to overide this method

I have an interest in creating some Java object which will "listen for
a certain time" and then trigger.  For example, I'd like the object to
wake up 6:00AM and do something.  I'd like the object to react to the
arrival of a certian time_of_day on certain days.  Does anyone know how

we have a very serious problem with timezones. Basically the default
timezone is changing for no apparent reason back to UTC, but only after
some time has lapsed since application start. This totally messes up any
date/time output and calculations.

Help...   I have just been presented with the responsibility of supporting a
JSP application.  The person who was handling EVERYTHING has left us (Rest

The first thing I need to do is create a backup server and copy the

I have been experimenting rewriting code using enums to see how they
differ from the old int style and class style kludged enums.
Enums have a number of rough edges.
1. they are not inner classes, at least I have not yet figured out how

I am writing a JNI application to call a C++ code from Java.
In JNI code, I'm creating a Java String from char* using NewStringUTF
and then calling ReleaseStringUTFChars on this string.
However, my program crashes on ReleaseStringUTFChars.
