public class Boolean
extends Object
The Boolean class is a wrapper object with the same functionality as the standard JavaScript
Boolean object. Use the Boolean class to retrieve the primitive data type or string
representation of a Boolean object.
You must use the constructor new
Boolean() to create a Boolean object before calling its
methods.
