public final class Boolean

Object
Boolean

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. Since: JDK1.0, CLDC 1.0

Fields

`public static final` `Boolean FALSE`	The Boolean object corresponding to the primitive value false.
`public static final` `Boolean TRUE`	The Boolean object corresponding to the primitive value true.

Constructors

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

Methods

`public boolean booleanValue()`	Returns the value of this Boolean object as a boolean primitive.
`public boolean equals(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.
`public int hashCode()`	Returns a hash code for this Boolean object.
`public` `String toString()`	Returns a String object representing this Boolean’s value.
`public static` `Boolean valueOf(boolean b)`	Returns the object instance of i
`public static` `Boolean valueOf(String b)`
`public static boolean parseBoolean(String s)`
`public int compareTo(Boolean b2)`

Constructor details

Boolean

public Boolean(boolean value)

Allocates a Boolean object representing the value argument. value - the value of the Boolean.

Method details

booleanValue

public boolean booleanValue()

Returns the value of this Boolean object as a boolean primitive.

equals

public boolean equals(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.

hashCode

public int hashCode()

Returns a hash code for this Boolean object.

toString

public String toString()

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.

valueOf

public static Boolean valueOf(boolean b)

Returns the object instance of i

Parameters

b boolean: the primitive

Returns

object instance

valueOf

public static Boolean valueOf(String b)

parseBoolean

public static boolean parseBoolean(String s)

compareTo

public int compareTo(Boolean b2)
