it says error in line 57: type expected. i have pointed to the error next to it.i am trying to draw a box as an array horizontally on the left of the screen.

Re: some silly simple mistake..
hai,
the for loop is not inside any method, it open outside the class thats why givein the error
regs,

Re: some silly simple mistake..
thanks Bharat,
i put he counter in the "draw" method. now it compiles, but doesnt show anything in the appletviewer.I think theres something
wrong where i have called Graphics g: i have put no method in the {} there. what do i need to put there? if not there, where is the
error? thanks again..
