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`

## Method Summary

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
