    "won't work" tells us little, and if you need our help, consider giving us more details on your problem. The better the information you can give us, usually the better the help we can give back.

    Default Re: Try and catch

    It seems you are trying to use multiple-exception catches. What problems are you having exactly? What errors is your compiler throwing at you, if any?

    try {
         // stuff
    } catch (Exception1 | Exception2 ex) {
         // Handle both exceptions
    }

    try {
         // stuff
    } catch (SuperException ex) {
         if (ex instanceof Exception1 || ex instanceof Exception2) {
             // handle exception
         }
    }
