Question

I prefer not to use SuppressWarnings. I prefer to write code that produces no complaints. I import the apache.commons class PropertiesConfiguration.

This file was created with a text editor:

numbers = 0.222,0.333
animals = dog,cat

I then read the file into an instance of PropertiesConfiguration, say it is referenced by “pc”.

                List<String> myStringList = pc.getList("animals");

The call to getList() produces a compile-time warning about unchecked conversions. How do I improve this without SupressWarnings?

Answer 1

It looks like getList() returns a generic List object. How about using getStringArray() instead which returns an array of Strings?
