The order() method of java.nio.CharBuffer class is used to retrieve this buffer’s byte order. The byte order of a char buffer created by allocation or by wrapping an existing char array is the native order of the underlying hardware. The byte order of a char buffer created as a view of a byte buffer is that of the byte buffer at the moment that the view is created.
Syntax:
public abstract ByteOrder order()
Return Value: This method returns this buffer’s byte order.
Below are the examples to illustrate the order() method:
Examples 1:
// Java program to demonstrate // order() method import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
// creating object of CharBuffer
// and allocating size capacity
CharBuffer cb
= CharBuffer.allocate( 4 );
// append the int value in the charbuffer
cb.append( 'a' )
.append( 'b' )
.append( 'c' )
.append( 'd' );
// rewind the Bytebuffer
cb.rewind();
// Retrieve the ByteOrder
// using order() method
ByteOrder order = cb.order();
// print the char buffer and order
System.out.println( "CharBuffer is : "
+ Arrays.toString(cb.array())
+ "\nOrder: " + order);
}
} |
CharBuffer is : [a, b, c, d] Order: LITTLE_ENDIAN
Examples 2:
// Java program to demonstrate // order() method import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
// creating object of CharBuffer
// and allocating size capacity
CharBuffer cb = CharBuffer.allocate( 4 );
// Retrieve the ByteOrder
// using order() method
ByteOrder order = cb.order();
// print the char buffer and order
System.out.println( "CharBuffer is : "
+ Arrays.toString(cb.array())
+ "\nOrder: " + order);
}
} |
CharBuffer is : [,,, ] Order: LITTLE_ENDIAN
