Reading and writing Serializable objects

See following example :


/**

import java.io.*;
import java.util.*;

public class ExerciseSerializable {

    public static void main(String... aArguments) {
        //  create a Serializable Map
        Map<Integer, String> names = new HashMap<Integer, String>();
        names.put(1, "prasobh");
        names.put(2, "mohanlal");
        names.put(3, "mammokka");



        try {
            //  use buffering
            OutputStream file = new FileOutputStream("names.store");
            OutputStream buffer = new BufferedOutputStream(file);
            ObjectOutput output = new ObjectOutputStream(buffer);
            try {
                output.writeObject(names);
            } finally {
                output.close();
            }
        } catch (IOException ex) {
            System.out.println("Exception " + ex);
        }

        // deserialize the quarks.ser file


        try {
            //use buffering
            InputStream file = new FileInputStream("names.store");
            InputStream buffer = new BufferedInputStream(file);
            ObjectInput input = new ObjectInputStream(buffer);
            try {
                //deserialize the List

                Map<Integer, String> recoverednames = (Map<Integer, String>) input.readObject();

                //display its data

                System.out.println("recoverednames: " + recoverednames);

            } finally {
                input.close();
            }
        } catch (ClassNotFoundException ex) {
            System.out.println("Exception " + ex);
        } catch (IOException ex) {
            System.out.println("Exception " + ex);
        }
    }
}
