In this tutorial you will learn about how to order bytes from most significant to least significant.

Order bytes from most significant to least significant.

In this tutorial we will discuss on how to use the ByteOrder class for ordering bytes from most significant to a least significant.

Code:

import java.nio.ByteBuffer;
import java.nio.ByteOrder;

public class ByOrderDemo {

  public static void main(String[] args) {
    ByteBuffer byteBuf = ByteBuffer.wrap(new byte[6]);
    byteBuf.asCharBuffer().put("abc");
    System.out.println(toString(byteBuf.array()));
    byteBuf.rewind();

    byteBuf.order(ByteOrder.BIG_ENDIAN);
    byteBuf.asCharBuffer().put("abc");
    System.out.println(toString(byteBuf.array()));
    byteBuf.rewind();

   }

  static String toString(byte[] a) {
    StringBuffer strbuf = new StringBuffer();
    for (int i = 0; i < a.length; i++) {
      strbuf.append(a[i]);
      if (i < a.length - 1)
        strbuf.append(", ");
    }
    return strbuf.toString();
  }
}

Output:

  0, 97, 0, 98, 0, 99
  0, 97, 0, 98, 0, 99
