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()); 
            }
