How can detect one string contain one of several characters using java regex

Question

I have a variable length string, I just want to detect whether this string contains several characters. For example:

"sadsdd$sss^dee~"

I want to detect whether this string contains ANY of the following: $ ^ ~. How can I do that using Java string.matches?

"sadsdd$sss^dee~".matches("[^+$+~+]");

Answer 1

Use a pattern and a matcher for that:

Pattern pattern = Pattern.compile("[$~^]");
Matcher matcher = pattern.matcher(input);
if (matcher.find()) {
   // contains special characters
} else {
   // doesn't contain special characters
}
