title: Export ByteBuffer as Little Endian File in Java
body: <p>I want to Export a ByteBuffer as Little Endian into a file, but when I read in the file again I have to read it as Big Endian to get the right values. How can I export a ByteBuffer in a way that I can read in the created file as Little Endian and get the right values?</p>
  
  <pre><code>    //In the ByteBuffer tgxImageData there are the bytes which I want to export and import again, the ByteBuffer is ordered as little endian
  
  
      //export ByteBuffer into File
      FileOutputStream fos = new FileOutputStream(outputfile);            
      tgxImageData.position(0);
      byte[] tgxImageDataByte = new byte[tgxImageData.limit()];
      tgxImageData.get(tgxImageDataByte);         
      fos.write(tgxImageDataByte);            
      fos.close();
  
  
      //import File into ByteBuffer
      FileInputStream fis2 = new FileInputStream(outputfile);     
      byte [] arr2 = new byte[(int)outputfile.length()];
      fis2.read(arr2);
      fis2.close();           
      ByteBuffer fileData2 = ByteBuffer.wrap(arr2);
  
  
      fileData2.order(ByteOrder.LITTLE_ENDIAN);           
      System.out.println(fileData2.getShort(0));          //Wrong output, but here should be right output
      fileData2.order(ByteOrder.BIG_ENDIAN);          
      System.out.println(fileData2.getShort(0));          //Right output, but here should be wrong output
