Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Constructors

public Number ()

Added in API level 1

Empty default constructor.

Public Methods

public byte byteValue ()

Added in API level 1

Returns this object's value as a byte. Might involve rounding and/or truncating the value, so it fits into a byte.

Returns
`byte`	the primitive byte value of this object.

public abstract double doubleValue ()

Added in API level 1

Returns this object's value as a double. Might involve rounding.

Returns
`double`	the primitive double value of this object.

public abstract float floatValue ()

Added in API level 1

Returns this object's value as a float. Might involve rounding.

Returns
`float`	the primitive float value of this object.

public abstract int intValue ()

Added in API level 1

Returns this object's value as an int. Might involve rounding and/or truncating the value, so it fits into an int.

Returns
`int`	the primitive int value of this object.

public abstract long longValue ()

Added in API level 1

Returns this object's value as a long. Might involve rounding and/or truncating the value, so it fits into a long.

Returns
`long`	the primitive long value of this object.

public short shortValue ()

Added in API level 1

Returns this object's value as a short. Might involve rounding and/or truncating the value, so it fits into a short.

Returns
`short`	the primitive short value of this object.
