Class java.lang.Boolean 

java.lang.Object
   |
   +----java.lang.Boolean
public final class Boolean
extends Object
The Boolean class provides an object wrapper for Boolean data values, and serves as a place for boolean-oriented operations. A wrapper is useful because most of Java's utility classes require the use of objects. Since booleans are not objects in Java, they need to be "wrapped" in a Boolean instance.

Variable Index

o FALSE
Assigns this Boolean to be false.
o MAX_VALUE
The maximum value a Character can have.
o MIN_VALUE
The minimum value a Charater can have.
o TRUE
Assigns this Boolean to be true.

Constructor Index

o Boolean(boolean)
Constructs a Boolean object initialized to the specified boolean value.
o Boolean(String)
Constructs a Boolean object initialized to the value specified by the String parameter.

Method Index

o booleanValue()
Returns the value of this Boolean object as a boolean.
o equals(Object)
Compares this object against the specified object.
o getBoolean(String)
Gets a Boolean from the properties.
o hashCode()
Returns a hashcode for this Boolean.
o toString()
Returns a new String object representing this Boolean's value.
o valueOf(String)
Returns the boolean value represented by the specified String.

Variables

o TRUE 
  public final static Boolean TRUE
Assigns this Boolean to be true.
o FALSE 
  public final static Boolean FALSE
Assigns this Boolean to be false.
