I have a problem. I am coding for a registeration page using struts and in password field I have to check whether the characters are in 0-9, a-z , A-Z. But the constraint here is the user must have one in each group i.e., one numberic, one lower case and one upper case. The code I have written here is below. I know it is checking either of these group, but how to make this code to fit for the constraint. Please help me , it urgent!!
Thanks in advance.
