public boolean matches(String regex) 매개변수로 받아온 정규 표현식(regex)와 문자열이 일치하는지 여부를 확인하는데에 사용된다. 정규표현식과 문자열전체가 일치해야만 true 값이 반환된다. 예시 String text = "Hello,123"; boolean isMatch = text.matches("[a-zA-Z]+,[0-9]+"); System.out.println(isMatch); // 출력: true 본인은 한글과 영어가 섞여있는 String 배열 사이에서 대소문자가 혼합되어있는 영어 문자열을 찾고싶어서 해당 메소드를 사용하였다.
