java.util.regex.Matcher class represents the engine for executing various matching operations. This class has no constructor and can be usedmatches()
The method of the class java.util.regex.Pattern to create/Get an object of this class.
This (matcher)'stoMatchResult()The method returns the current matching state of the matcher.
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 expressions to match the content of bold tags String regex = "<b>(\\S+)</b>"; //Create a pattern object Pattern pattern = Pattern.compile(regex); //Match 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()); } }
Output result
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>]
