Questions tagged [apache-commons-lang3]

Apache Commons Lang3 provides a number of helper classes for things that are deemed missing in the Java base libraries. This includes string handling, mathematics helpers, reflection helpers, concurrency and others. Version 3 is a backwards incompatible version update of the original Apache Commons Lang library.

Apache Commons Lang 3 is the latest version of the library.

Note that Lang 3.0 (and subsequent versions) use a different Java package (org.apache.commons.lang3) than the previous versions (org.apache.commons.lang), allowing it to be used at the same time as an earlier version.
