We’ve recently included libraries for Apache Commons Lang. There is a large number of useful things in there, but I find most use for stringUtils and wordUtils.
For example, some sites one might scrape might have the results in all caps. You could:
import org.apache.commons.lang.*;
name = “GEORGE WASHINGTON CARVER”;
name = StringUtils.lowerCase(name);
name = WordUtils.capitalize(name);
session.log(“Name now shows as: ” + name);
At the end, the name is now formatted as “George Washington Carver”. Most all of the methods are already nullsafe, and there is a lot of little tools in there to try.
