# Class ByteOrder

java.lang.Object
java.nio.ByteOrder

public final class ByteOrder extends Object
A typesafe enumeration for byte orders.

Since:
  1.4

- ## Field Summary

  Fields
  Modifier and Type
  Field
  Description
  `static final ByteOrder`
  `BIG_ENDIAN`
  Constant denoting big-endian byte order.
  `static final ByteOrder`
  `LITTLE_ENDIAN`
  Constant denoting little-endian byte order.

- ## Method Summary

  Modifier and Type
  Method
  Description
  `static ByteOrder`
  `nativeOrder()`
  Retrieves the native byte order of the underlying platform.
  `String`
  `toString()`
  Constructs a string describing this object.

- ## Field Details

  - ### BIG_ENDIAN

    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

    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.

- ## Method Details

  - ### nativeOrder

    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:
      The native byte order of the hardware upon which this Java virtual machine is running

  - ### toString

    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`.

    Overrides:
      `toString` in class `Object`
    Returns:
      The specified string
