  { BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
    try

      String n=br.readLine();
      System.out.print("Enter your password : ");
      String m=br.readLine();
      if(m.length() <6)
        throw new myException();
      System.out.print("Enter your age : ");
      int o=Integer.parseInt(br.readLine());
      if(o<18)
