Since we are optimizing this, you do not have to instanciate an object of type Integer in order to use its methods.  There is a name
for this type of class but it has eluded me.  Here is the optimized version:

int i = Integer.parseInt(txtField1.getText());

The advantage here is that there is no object instanciated and therefore it has NO scope rather than it sticking around for any
length of time.  Not that having it sticking around is a problem, just a mental exercise.
