Assume that validData is a variable of type boolean that has been declared. 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 which is NumberFormatException. Write some code that invokes the process method provided by the object associated with processor and arrange matters so that any NumberFormatException that is thrown is caught and causes validData to be set to false.

CHALLENGE:

Assume that validData is a variable of type boolean that has been declared. 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 which is NumberFormatException. Write some code that invokes the process method provided by the object associated with processor and arrange matters so that any NumberFormatException that is thrown is caught and causes validData to be set to false.

SOLUTION:

try {
   processor.process();
}
catch(NumberFormatException nfe) {
   validData=false;
}
