Greetings

 

I am working through the lab 1007 - Exercise 1.3 "Experience various
Exceptions".

 

For most of the radio buttons, the java.lang.NullPointerException is
displayed.

 

I was expecting different exceptions being caught, for each of the radio
buttons.

 

In looking through the code, I have noticed that an array "private double[]
a;" is declared but I do not see any place where the array is initialized.

 

Am I missing something? I will appreciate your comments.

 

Thanks

 

Mahesh
