        System.out.println(email);
        String expression="^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";
                   CharSequence inputStr=email;
                   Pattern pattern=Pattern.compile(expression);
                   Matcher matcher=pattern.matcher(inputStr);
                   String msg="Email is not in Proper Format";
                   if(matcher.matches()){
