Helo all,

I need one regular expression pattern, in that i have to verify string contains at least one upper or lower case character or one number i dont have problem with position. if string contains only special charactors it will be invalid. EX : @#@#@# invalid string !@$%^&a - valid string !@$$)(&A - valid string !@$$)(&1 - valid string
can you please help me to prepare Pattern String regExp = '([a-zA-Z0-9]*)';

for(string regEx : regExps)
//system.debug('regEx== '+regEx); Matcher m = Pattern.compile(regExp).matcher(regEx); if(m.matches()) { System.debug(regEx); }
