We can ignore it, default value is returned when the type is undefined.

It is ".NumberFormatException" error.

Why do you set "undefined" string as a default value?


If you accept such a situation, the default value should be 0(for example, 0 is a number).


This trouble is happening because "undefined" string comes into the Number variable.


Let's keep zero warnings, zero errors, of course, zero exceptions.
