Input and output of primitive values with random access binary files

import java.io.RandomAccessFile;

public class InputOutputDemoPrimitive {

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

    //Read and write parts of file "raf.dat" in arbitrary order:
    RandomAccessFile raf = new RandomAccessFile("r.dat", "rw");
    raf.writeDouble(3.1415);
    raf.writeInt(42);
    raf.seek(0);
    System.out.println(raf.readDouble() + " " + raf.readInt());
