Update July 2019

Currently, the most up-to-date library function for doing this is contained in org.apache.commons.lang3.StringUtils

import org.apache.commons.lang3.StringUtils;

StringUtils.capitalize(myString);

If you're using Maven, import the dependency in your pom.xml:

  org.apache.commons
  commons-lang3
