Code of the program is given below:

 

 

import java.io.*;

public class ForcingUpdates
{
  public static void main(String[] args
  {
  try 
  {
  // Open or create the output file
  OutputStream os = new FileOutputStream("tapan.txt");
  
  // Write some data to the stream
  byte[] data = new byte[]
  {
  (byte)124,(byte)66 };
  os.write(data);
  os.close();
  
  catch (IOException e
  {
  System.out.println("The exception has been thrown : " + e);
  }
  System.out.println("Congrats you have entered the text forcefully");
  }
