The use of DataOutputStream and DataInputStream:

  

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

class DataIODemo {
  public static void main(String args[]) throws IOException {

    FileOutputStream fout = new FileOutputStream("Test.dat");
    DataOutputStream out = new DataOutputStream(fout);

    out.writeDouble(98.6);
    out.writeInt(1000);
    out.writeBoolean(true);

    out.close();

    FileInputStream fin = new FileInputStream("Test.dat");
    DataInputStream in = new DataInputStream(fin);

    double d = in.readDouble();
    int i = in.readInt();
    boolean b = in.readBoolean();

    System.out.println("Here are the values:  " + d + " " + i + " " + b);

    in.close();
  }
