prog of multiple inputs

[nick kaushik]

hi.... i want to take user input many times on command-line...the program replaces a char of user's choice with char of user's choice...

   import java.io.*;
 public class Lb
{  
  public static void main(String arg[]) throws IOException
 {
  char a;
  BufferedReader br= new BufferedReader(new InputStreamReader(System.in));
  BufferedReader br1= new BufferedReader(new InputStreamReader(System.in));
  BufferedReader br2= new BufferedReader(new InputStreamReader(System.in));
  
  System.out.println("enter the text");
  String s=br.readLine();
  String s1;
             do
              { 
               System.out.println("enter the char u want to replace");
               char c=(char)br.read();
               System.out.println("enter the replacement");
               char r=(char)br1.read();
               s1=s.replace(c,r);
               System.out.println(s1);	
               System.out.println("replace again-y/n?");
               a=(char)br2.read(); 
               } while(a!='n');

  System.out.println(s1); 
  }
} 

i know that String Buffer should be used but still this program throws strange output....
