i am doin my college assignment. im trying to create the old
defender game but a more stylish version, the thing is i am doing my
project in java instead of visual basic like the rest of the class
and my tutors do not know any java so can not help me.

i am stuck on multi-threading, ive got 1 thread that controls certain
object and there speed, but i tried creating a second thread that has
a shorter interval but it did not work.

also i am stuck on the 'bullets' that will fire from my ship. and how
to create the enemy ships, i have done quite a bit of the program and
just need to sort out these bits and i will have finished.
