Need help parsing doubles using JOptionPane
When I am done I get no errors in eclipse but when I go to run the program I get errors telling me my variables may not have been initialized and the program fails. Here is a look at my code.

JOptionPane com double - Assuntos Gerais - GUJ
If he initializes the values with null or "", another exception will be thrown.

But I thought that eclipse would have thrown and error if I was wrong but it didn't. Here is a look at the code I turned in.
