Java-Judging Special Characters

Sample code (runnable)

String regEx = "[ _`~!@#$%^&*()+=|{}':;',\\[\\].<>/?~！@#￥%……&*（）——+|{}【】‘；：”“’。，、？]|\n|\r|\t";

public static void main(String[] args) {
	System.out.println(hasSpecialChar("", regEx));
	System.out.println(hasSpecialChar(" ", regEx));
	System.out.println(hasSpecialChar("faf", regEx));
	System.out.println(hasSpecialChar("fa fa", regEx));
	System.out.println(hasSpecialChar("fa(", regEx));
}

public static boolean hasSpecialChar(String str, String regEx) {
	Pattern p = Pattern.compile(regEx);
	Matcher m = p.matcher(str);

	return m.find();
}

The above code can run, but the special characters do not include the minus sign ("-"). If you want to filter the minus sign, you need to do special processing ("\\-").

String regEx1 = "[_`~!@#$%^&*()\\-+=|{}':;',\\[\\].<>/?~！@#￥%……&*（）——+|{}【】‘；：”“’。，、？]|\n|\r|\t";

The minus sign is special and special, as a sign.
