Hi,
I am an experienced Java developer, and I am highly expert at any Java development (e.g., desktop, Web-based), among other languages and technologies. I understand that you have a Java programming assignment, and I can help you complete it. If you can provide more details about your assignment, that would really help.
By the way, I have worked with Australians before, and they are very kind to work with.
Respectfully yours,
Mark
