Commons Lang
Commons Lang - an extension of the java.lang package

The Apache Commons Lang software library provides a host of helper utilities for the java.lang API, notably String manipulation methods, basic numerical methods, object reflection, concurrency, creation and serialization and System properties. Additionally it contains basic enhancements to java.util.Date and a series of utilities dedicated to help with building methods, such as hashCode, toString and equals. Current support includes:

  • StringUtils - Helper for java.lang.String.
  • CharSetUtils - Methods for dealing with CharSets, which are sets of characters such as [a-z] and [abcdez].
  • RandomStringUtils - Helper for creating randomised Strings.
  • NumberUtils - Helper for java.lang.Number and its subclasses.
  • NumberRange - A range of numbers with an upper and lower bound.
  • ObjectUtils - Helper for java.lang.Object.
  • SerializationUtils - Helper for serializing Objects.
  • SystemUtils - Utility class defining the Java system properties.
  • NestedException package - A sub-package for the creation of nested exceptions.
  • Enum package - A sub-package for the creation of enumerated types.
  • Builder package - A sub-package for the creation of equals, hashCode, compareTo and toString methods.
