import java.io.*;

public class Demo {
    public static void main(String[] args) {
        try {
            // create a new file with an ObjectOutputStream
            FileOutputStream out = new FileOutputStream("test.txt");
            ObjectOutputStream oout = new ObjectOutputStream(out);

            // write something in the file
            oout.writeUTF("Hello World");
            oout.flush();

            // create an ObjectInputStream for the file we created before
            ObjectInputStream ois = new ObjectInputStream(new FileInputStream("test.txt"));

            // read from the stream
            for (int i = 0; i < ois.available();) {
                System.out.print("" + (char) ois.read());
            }

            // change line
            System.out.println();

            // close the stream
            System.out.println("Closing Stream...");
            ois.close();
            System.out.println("Stream Closed.");
        } catch (Exception ex) {
            ex.printStackTrace();
