Using regex in java

Question

I need to get a name from the text box and store it in a String variable.And i should put a condition that the name that is stored in the stirng variable should not start with non alpha numeric characters or special characters.For this i want to use Regular expressions in java.I got a Regex or pattern for this purpose it is shown below
Pattern:
^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})$
And my code is as follows:
JTextFeild reportnametext;
String name=reportnametext.getText();
//here i need to check whether the first charecter of the name is starting with a special character and if it starts with special charecter i need to popup a dialog box that name should not start with special characters.
Can u plz show me how to implement it in my code

If you'd have taken the time to go through the links I provided you would have seen [url http://javaalmanac.com/egs/java.util.regex/Case.html]Setting Case Sensitivity in a Regular Expression.
Pattern p = Pattern.compile("^[a-z0-9]", Pattern.CASE_INSENSITIVE);Regards
