<p >
The standard Java libraries fail to provide enough methods for
manipulation of its core classes. The <em > Lang</em> Component provides
these extra methods.
</p>
<p >
The <em > Lang</em> Component provides a host of helper utilities for the java.lang API, notably
String manipulation methods, basic numerical methods, object reflection, creation and serialization,
and System properties. Additionally it contains an inheritable enum type, an exception structure that
supports multiple types of nested-Exceptions, basic enhancements to java.util.Date and a series of utlities dedicated to help with
building methods, such as hashCode, toString and equals.
