In Java, how to define the endian of the data being written when using dataoutputstream to write a file?

I am using dataoutputstream to write to the file, but I want to change the endian of the data

This is how I write byte data to a file (output as little end by default)

public void generateBinObjFile(String outputFile)
    try {
        // Create file

        DataOutputStream stream = new DataOutputStream(
                new FileOutputStream(outputFile));

        stream.writeShort(this.quantize(this.xComponents.get(index),//<-- Short is written in little Endian
                    this.min_x,this.max_x) - 32768);

        } // catch statements here

Is there any way to define endian written in Java for byte data?

Solution

You can't use dataoutputstream to do this. It always uses the big end

You can use ByteBuffer to call order () to affect how it reads and writes data

You can use ByteBuffer to prepare a byte [], which you will write later using the classic OutputStream or go completely to NiO and write using any writablebytechannel
