java.util.regex.Matcher 클래스는 다양한 일치 작업을 수행하는 엔진을 나타냅니다. 이 클래스에 대한 생성자가 없습니다. java.util.regex.Pattern 클래스의 match() 메소드를 사용하여 이 클래스의 객체를 생성/얻을 수 있습니다.
toString() Matcher 클래스의 메소드는 현재 matcher 객체의 내용을 나타내는 문자열 값을 반환합니다.

import java.util.Scanner; import java.util.regex.Matcher; import java.util.regex.Pattern; public class ToStringExample { public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("Enter input text: "); String input = sc.nextLine(); String regex = "[#%&*]"; //Creating a pattern object Pattern pattern = Pattern.compile(regex); //Creating a Matcher object Matcher matcher = pattern.matcher(input); int count =0; while(matcher.find()) { count++; } //Retrieving Pattern used System.out.println("The are "+count+" special [# % & *] characters in the given text"); System.out.println("Following is the string format of the matcher used: \n"+matcher.toString()); } }
출력
