    Default Re: i'm getting this error, dont know why? please help

    examine your code:
                System.out.println("sw.getDimX ="+sw.getDimX+" "+"sw.getDimY ="+sw.getDimY);
                System.out.println("sw.setDimX ="+sw.setDimX+" "+"sw.setDimY ="+sw.setDimY);

    I'm assuming you meant to call the methods getDimX() rather than try to get a field named getDimX (same thing for getDimY). I don't know why you're trying to print out setDimY, usually set denotes void method which allows you to set a variable's value.

    Thumbs up Re: i'm getting this error, dont know why? please help

    Yeah, exactly as said above. You shouldn't print anything inside a setter method as it is usually a VOID, which means returns nothing.

    The only thing you need is following line of code instead of the two lines you have mentioned above,

    System.out.println("sw.getDimX ="+sw.getDimX()+" "+"sw.getDimY ="+sw.getDimY());
    Hope that helps!
