If you’re using it to put in a DB you might want to do this after the regex:
//This will insure that you have a proper int
while(num .startsWith(“0″) && num.length() > 1){//loop through the string and make sure it doesn’t start with a 0
num = num .substring(1, num .length());
}
//Then you can do.
Integer.valueOf(num);
