ByteOrder

public final class ByteOrder
extends Object

java.lang.Object
↳	java.nio.ByteOrder

A typesafe enumeration for byte orders.

Summary

Fields
`public static final ByteOrder`	`BIG_ENDIAN` Constant denoting big-endian byte order.
`public static final ByteOrder`	`LITTLE_ENDIAN` Constant denoting little-endian byte order.

Public methods
`static ByteOrder`	`nativeOrder()` Retrieves the native byte order of the underlying platform.
`String`	`toString()` Constructs a string describing this object.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Fields

BIG_ENDIAN

Added in API level 1

public static final ByteOrder BIG_ENDIAN

Constant denoting big-endian byte order. In this order, the bytes of a multibyte value are ordered from most significant to least significant.

LITTLE_ENDIAN

Added in API level 1

public static final ByteOrder LITTLE_ENDIAN

Constant denoting little-endian byte order. In this order, the bytes of a multibyte value are ordered from least significant to most significant.

Public methods

nativeOrder

Added in API level 1

public static ByteOrder nativeOrder ()

Retrieves the native byte order of the underlying platform.

This method is defined so that performance-sensitive Java code can allocate direct buffers with the same byte order as the hardware. Native code libraries are often more efficient when such buffers are used.

Returns
`ByteOrder`	The native byte order of the hardware upon which this Java virtual machine is running

toString

Added in API level 1

public String toString ()

Constructs a string describing this object.

This method returns the string "BIG_ENDIAN" for BIG_ENDIAN and "LITTLE_ENDIAN" for LITTLE_ENDIAN.

Returns
`String`	The specified string
