need help with moving objects
well i've been assigned to make a simple java game but im already having trouble 
.. i need to get something to move across the screen. I'm trying to get a rectangle to go across the top portion of the application. ofc I've youtubed and everything but i still get this smudge across the top of the screen when i do the fillRet ; when i do drawRect i get a bunch of lines spaced across. In case your curious of what im trying to make, i will be attempting to make a game sorta like fruit ninja. Much much simpler of course. Currently i just need to get an object to move :L Once i do that ill add pictures mouse stuff etc..Here's the code.
