Examples of com.google.common.base.Splitter

com.google.common.base.Splitter
Do not do this! Splitter splitter = Splitter.on('/'); splitter.trimResults(); // does nothing! return splitter.split("wrong / wrong / wrong");} The separator recognized by the splitter does not have to be a single literal character as in the examples above. See the methods {@link #on(String)}, {@link #on(Pattern)} and {@link #on(CharMatcher)} for examplesof other ways to specify separators.
Note: this class does not mimic any of the quirky behaviors of similar JDK methods; for instance, it does not silently discard trailing separators, as does {@link String#split(String)}, nor does it have a default behavior of using five particular whitespace characters as separators, like {@link java.util.StringTokenizer}. @author Julien Silland @author Jesse Wilson @author Kevin Bourrillion @author Louis Wasserman @since Guava release 01
