Create a read-only memory-mapped file


 

import java.io.File;

import java.io.RandomAccessFile;

import java.nio.ByteBuffer;

import java.nio.channels.FileChannel;



public class Main {

  public static void main(String[] argv) throws Exception {

    File file = new File("filename");

    // Create a read-only memory-mapped file

    FileChannel roChannel = new RandomAccessFile(file, "r").getChannel();



    ByteBuffer readonlybuffer = roChannel.map(FileChannel.MapMode.READ_ONLY, 0, (int) roChannel

        .size());





  }
