    Default Re: Need help with this code urgent please, i appreciate it.

    First, I'm wondering if you either forgot a bracket, added too many, or added or left out a ;.

    Hmmmmm...found a problem.


    Rectangle p1 = newRectangle(WIDTH/9,HEIGHT/2, WIDTH/30,HEIGHT/30);
    Rectangle p2 = newRectangle(((WIDTH/9)+ ((int)((WIDTH/9)*1.5)/2)), (HEIGHT/2)+
    (HEIGHT/10),WIDTH/30,WIDTH/30);

    There's no method in your program called newRectangle().

    "try without catch"
    Where are you getting that error?
    Is the next symbol after the try a {?
    Where is the matching }?
    What is the next symbol after the }?
    The compiler would like there to be a catch(..){..} there.

    try{...}catch(...){...} is the full syntax of a try/catch statement.
