In Java, is there any way to create an instance of any class that extends abstract class A, inside a member method of class A?

I'd like to merge 2 XML streams (strings) in Java, necessarily by XSLT (that I could change the transformation), but the problem is that the XMLs come as a string. There are many examples, but through the files.
Can this be done without saving them in files?
Thanks.

I am trying to parse a string which in JSON format only that keys are not enclosed in quotes. I can very well parse this string in Javascript, but can not find a Java API which will help me parse this. All the APIs I tried assumes strict JSON format.
Can anyone suggest a library which has an option to parse this, or a whole new approach to the problem (say like use regex instead) ?
I'm writing a program that uses scp to copy files in a bigger java program. As it stands now, the program freezes up while the scp is copying the file, which can take a few minutes, so I'd like to be able to display the progress of the scp or at the very least get the terminal window with the scp progress to show up! Any suggestions?
Hi,
Does anyone know a library to compare addresses in Java ?
Something that would give equality on addresses, written in different ways.
For example, it should recognize that
"22 Acacia Avenue" and "22 acacia av."
is the same address.
Of course, this can escalate a lot, that's why i'm asking.
Thanks in advance.

I'm trying to extend a Java Swing component in Clojure, i.e. I want to extend a javax.swing.JComponent and add some custom methods implemented in pure Clojure in addition to all the standard inherited methods.
I've tried using "proxy" which works great if I just want a single instance (in the same way as an anonymous inner class). However I'd really like a named class so that I can generate an arbitrary number of instances.
What's the recommended way of doing this?

What are the things in the language or the API that you don't like or would design differently?
