  Check this program .i have tried this by using both do while and while loop
  
  using while loop output is perfect but using do while there is one extra character added
  
  since in do while which is exit controlled loop first statement is executed then condition is checked therefore an extra character is added but in case of while loop which is entry controlled loop the ouptut is correct
  

  import java.io.*;
  public class T
  {
  public static void main(String args[])throws IOException
  {
  FileInputStream f=new FileInputStream("monu.txt");
  InputStreamReader isr=new InputStreamReader(f);
  BufferedReader b=new BufferedReader(isr);
  int t;
  FileOutputStream ff=new FileOutputStream("kumar.txt");
  OutputStreamWriter osr=new OutputStreamWriter(ff);
  BufferedWriter br=new BufferedWriter(osr);
  /*while((t=b.read())!=-1)
  {
  br.write((char)t);
  }*/
  
  do
  {
  t=b.read();
  br.write((char)t);
  }
  while(t!=-1);
  br.close();
  b.close();
  }
  }
