The Boolean object that represents the primitive value
false.
The Boolean object that represents the primitive value
true.
The Class object that represents the primitive type boolean.
Constructs a new Boolean with its boolean value specified by
string. If string is not null and is equal to
"true" using a non-case sensitive comparison, the result will be a
Boolean representing the primitive value true, otherwise it will
be a Boolean representing the primitive value false.
| string | the string representing a boolean value. |
|---|
Constructs a new Boolean with the specified primitive boolean
value.
| value | the primitive boolean value, true or false.
|
|---|
Gets the primitive value of this boolean, either true or
false.
Developers
true or false.
Compares two boolean values.
Compares this object to the specified boolean object to determine their relative order.
| that | the boolean object to compare this object to. |
|---|
that are
equal; a positive value if the value of this boolean is
true and the value of that is false; a
negative value if the value if this boolean is false and
the value of that is true.Compares this instance with the specified object and indicates if they
are equal. In order to be equal, o must be an instance of
Boolean and have the same boolean value as this object.
| o | the object to compare this boolean with. |
|---|
true if the specified object is equal to this
Boolean; false otherwise.
Returns the boolean value of the system property identified by
string.
| string | the name of the requested system property. |
|---|
true if the system property named by string
exists and it is equal to "true" using case insensitive
comparison, false otherwise.Returns an integer hash code for this boolean.
1231 for true
values and 1237 for false values.
Parses the specified string as a boolean.
| s | the string representation of a boolean value. |
|---|
true if s is not null and is equal to
"true" using case insensitive comparison, false
otherwise.Converts the specified boolean to its string representation.
| value | the boolean to convert. |
|---|
value is true, "false" otherwise.
Returns a string containing a concise, human-readable description of this boolean.
true, "false"
otherwise.
Parses the specified string as a boolean value.
| string | the string representation of a boolean value. |
|---|
Boolean.TRUE if string is equal to "true" using
case insensitive comparison, Boolean.FALSE otherwise.Returns a Boolean instance for the specified boolean value.
If it is not necessary to get a new Boolean instance, it is
recommended to use this method instead of the constructor, since it
returns its static instances, which results in better performance.
| b | the boolean to convert to a Boolean. |
|---|
Boolean.TRUE if b is equal to true,
Boolean.FALSE otherwise.
