table.
IntRange represents an inclusive range of ints.JVMRandom is a wrapper that supports all possible
Random methods via the Math.random() method
and its system-wide Random object.Operations to assist when working with a
Locale.LongRange represents an inclusive range of longs.Contains common code for working with Methods/Constructors, extracted and
refactored from

The base class of all exceptions which can contain other exceptions.
The base class of all runtime exceptions which can contain other
exceptions.
Thrown to indicate that a block of code has not been implemented.
Thrown to indicate that an argument was
null and should
not have been.NumberRange represents an inclusive range of
Number objects of the same type.Deprecated.
Use one of the Range classes in org.apache.commons.lang.math.
Provides extra functionality for Java Number classes.
Deprecated.

Operations on
Object.Class used as a null placeholder where
null
has another meaning.Operations for random
Strings.RandomUtils is a wrapper that supports all possible
Random methods via the Math.random()
method and its system-wide Random object.Range represents a range of numbers of the same type.

Assists with the serialization process and performs additional functionality based
on serialization.
Works with
ToStringBuilder to create a toString.StopWatch provides a convenient API for timings.Builds a string from constituent parts providing a more flexible and powerful API
than StringBuffer.

Strings for
Java, Java Script, HTML, XML, and SQL.Operations on
String that are
null safe.Lookup a String key to a String value.
Lookup implementation that uses a Map.
