I need to do a check on a string in java that allows the user to enter normal accents, but do not enter special characters such as @#!$! etc.
I did something similar to verify numeric and blank registration using 'matches'. Is there something similar for such a problem?
I do not know how you plan to implement it, but I'll show you two ways.
If you want to check character by character while typing, you can use Character.isLetterOrDigit(char) .
Another way would be to let the user type the String complete and then check later using StringUtils.isAlphanumeric(String)
