java.util.regex.Matcher 클래스는 다양한 일치 작업을 수행하는 엔진을 나타냅니다. 이 클래스에 대한 생성자가 없습니다. java.util.regex.Pattern 클래스의 matching() 메소드를 사용하여 이 클래스의 객체를 생성/얻을 수 있습니다.
toMatchResult() 이 메서드(Matcher)는 현재 matcher의 일치 상태를 반환합니다.

import java.util.regex.Matcher; import java.util.regex.Pattern; public class ToMatchResultExample { public static void main(String[] args) { String str = "<p>This <b>is</b> an <b>example</b>.</p>"; //Regular expression to match contents of the bold tags String regex = "<b>(\\S+)</b>"; //Creating a pattern object Pattern pattern = Pattern.compile(regex); //Matching the compiled pattern in the String System.out.println("State of the matcher: "); Matcher matcher = pattern.matcher(str); while (matcher.find()) { System.out.println(matcher.toMatchResult()); String result = matcher.group(1); } matcher = matcher.reset("<p>this is another <b>line</b>.</p>"); matcher.find(); System.out.println(""); System.out.println("State of the matcher after resetting it: \n"+matcher.toMatchResult()); } }
출력
State of the matcher: java.util.regex.Matcher[pattern=<b>(\S+)</b> region=0,40 lastmatch=<b>is</b>] java.util.regex.Matcher[pattern=<b>(\S+)</b> region=0,40 lastmatch=<b>example</b>] State of the matcher after resetting it: java.util.regex.Matcher[pattern=<b>(\S+)</b> region=0,35 lastmatch=<b>line</b>]
