java.lang.Object
   java.lang.Boolean

Boolean
final public class Boolean (Code)
The Boolean class wraps a value of the primitive type boolean in an object. An object of type Boolean contains a single field whose type is boolean.
version:
   12/17/01 (CLDC 1.1)
since:
   JDK1.0, CLDC 1.0


Field Summary
final public static  BooleanFALSE
     The Boolean object corresponding to the primitive value false.
final public static  BooleanTRUE
     The Boolean object corresponding to the primitive value true.

Constructor Summary
public  Boolean(boolean value)
     Allocates a Boolean object representing the value argument.

Method Summary
public  booleanbooleanValue()
     Returns the value of this Boolean object as a boolean primitive.
public  booleanequals(Object obj)
     Returns true if and only if the argument is not null and is a Boolean object that represents the same boolean value as this object.
Parameters:
  obj - the object to compare with.
public  inthashCode()
     Returns a hash code for this Boolean object.
public  StringtoString()
     Returns a String object representing this Boolean's value. If this object represents the value true, a string equal to "true" is returned.

Field Detail
FALSE
final public static Boolean FALSE(Code)
The Boolean object corresponding to the primitive value false.



TRUE
final public static Boolean TRUE(Code)
The Boolean object corresponding to the primitive value true.




Constructor Detail
Boolean
public Boolean(boolean value)(Code)
Allocates a Boolean object representing the value argument.
Parameters:
  value - the value of the Boolean.




Method Detail
booleanValue
public boolean booleanValue()(Code)
Returns the value of this Boolean object as a boolean primitive. the primitive boolean value of this object.



equals
public boolean equals(Object obj)(Code)
Returns true if and only if the argument is not null and is a Boolean object that represents the same boolean value as this object.
Parameters:
  obj - the object to compare with. true if the Boolean objects represent thesame value; false otherwise.



hashCode
public int hashCode()(Code)
Returns a hash code for this Boolean object. the integer 1231 if this object representstrue; returns the integer 1237 if thisobject represents false.



toString
public String toString()(Code)
Returns a String object representing this Boolean's value. If this object represents the value true, a string equal to "true" is returned. Otherwise, a string equal to "false" is returned. a string representation of this object.
