I wrote this method to check if the code valid or not:

private boolean validateDeleteBacklog(String code) {
        if(code != null && !code.equals("")) {
            if(code.length() == 6) {
                Pattern specialCaracter = Pattern.compile("[$&+,:;=?@#|'<>.-^*()%!]");
                boolean specialCar = specialCaracter.matcher(code).matches();
                return specialCar; 
            }
        }
        return false;
}

when i use code = "abc123" it return always false inside of true. Where is the problem here?

`if(code != null && !code.equals(""))` use `equals()` to compare String values – Hülya Aug 04 '20 at 15:48
@Hülya i did and when i try code="abc" it returns false inside of true – Sarah Aug 04 '20 at 15:52
debug your code to see what's going on... – Hülya Aug 04 '20 at 16:06
This is actually a completely different question. The problem now is that the whole string must match the pattern, but the pattern matches just one character. – Henry Aug 04 '20 at 16:06
@Henry Can you explain more please? – Sarah Aug 04 '20 at 16:15
