java - Rectangle.y issue, persistently rendering at 0 -

i'm trying render rectangle jpanel:

playerrect = new rectangle(100,100,10,10); 

problem is, playerrect renders @ 100,0 every time. i've updated eclipse , java, troubleshoot code , played x, y, width, height (although i'm not sure how code affect java.awt.rectangle).

any clue causing this?
