Below program illustrate the above method:
Program 1:
// Java program to illustrate// the above method  import java.io.*;  public class GFG {    public static void main(String[] args)    {        try {              // create a new file            // with an ObjectOutputStream            FileOutputStream out                = new FileOutputStream("gopal.txt");            ObjectOutputStream out1                = new ObjectOutputStream(out);              // write            out1.writeUTF("Geeks for Geeks");              // Flushes the stream            out1.flush();              // create an ObjectInputStream            // for the file            ObjectInputStream example                = new ObjectInputStream(                    new FileInputStream("gopal.txt"));              // Read from the stream            for (int i = 0; i < example.available();) {                System.out.print("" + (char)example.read());            }        }        catch (Exception ex) {            ex.printStackTrace();        }    }} |
