Explanation / Answer

Hi,

Please find below the answer without Copilation.

Have caught throwable in Petfood 2 function and caught exception in main function.

public class Tigers {
    public static void main(String args[]) {
        try {
            petfood1();
        } catch (CatException e) {
            System.err.println(e.getMessage() + " The stack trace is:");
            e.printStackTrace();
        } catch (Exception e) {
            System.err.println(e.getMessage() + " The stack trace is:");
            e.printStackTrace();
        }
    }

    public static void petfood1() throws Exception {
        petfood2();
    }

    public static void petfood2() throws Exception {
        try {
            petfood3();
        } catch (Throwable e) {
            throw new Exception();
        }
    }

    public static void petfood3() throws Throwable {
        throw new CatException();
    }
}

class CatException extends Exception {
    public CatException() {
        super("user defined exception.");
    }
}

Hope it helps.

Thanks,

Sri
