Answer / qim2010

ObjectInputStream is used for reading and ObjectOutPutSteam is
used for writing.

Here is a simple example:

import java.io.EOFException;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.ObjectInputStream;

/**
*
* @author javadb.com
*/
public class Main {

    /**
     * Example method for using the ObjectInputStream class
     */
    public void readPersons(String filename) {

        ObjectInputStream inputStream = null;

        try {

            //Construct the ObjectInputStream object
            inputStream = new ObjectInputStream(new
FileInputStream(filename));

            Object obj = null;

            while ((obj = inputStream.readObject()) != null) {

                if (obj instanceof Person) {

                    System.out.println(((Person)obj).toString());
                }

            }


        } catch (EOFException ex) { //This exception will be
caught when EOF is reached
            System.out.println("End of file reached.");
        } catch (ClassNotFoundException ex) {
            ex.printStackTrace();
        } catch (FileNotFoundException ex) {
            ex.printStackTrace();
        } catch (IOException ex) {
            ex.printStackTrace();
        } finally {
            //Close the ObjectInputStream
            try {
                if (inputStream != null) {
                    inputStream.close();
                }
            } catch (IOException ex) {
                ex.printStackTrace();
            }
        }
    }

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        new Main().readPersons("myFile.txt");
    }
}
