Assume that processor refers to an object that provides a void method named process that takes no arguments. As it happens, the process method may throw one of several exceptions. One of these is NumberFormatException, another is FileNotFoundException. And there are others. Write some code that invokes the process method provided by the object associated with processor and arranges matters so that if a NumberFormatException is thrown, the message “Bad Data” is printed to standard output, and if FileNotFoundException. is thrown, the message “Data File Missing” is printed to standard output. If some other Exception is thrown, its associated message is printed out to standard output.

CHALLENGE:

Assume that processor refers to an object that provides a void method named process that takes no arguments. As it happens, the process method may throw one of several exceptions. One of these is NumberFormatException, another is FileNotFoundException. And there are others. Write some code that invokes the process method provided by the object associated with processor and arranges matters so that if a NumberFormatException is thrown, the message “Bad Data” is printed to standard output, and if FileNotFoundException. is thrown, the message “Data File Missing” is printed to standard output. If some other Exception is thrown, its associated message is printed out to standard output.

SOLUTION:


try {
   processor.process();
}
catch(NumberFormatException nfe) {
   System.out.println("Bad Data");
}
catch(FileNotFoundException fnfe) {
   System.out.println("Data File Missing");
}
catch(Exception e) {
   System.out.println(e.getMessage());
}
