java.util.regex.Matcher class represents an engine for executing various matching operations. This class has no constructor, and it can be usedmatches()
Method created by the java.util.regex.Pattern class/Get an object of this class.
Anchoring boundaries are used for area matching, such as ^ and $. By default, the matcher uses anchoring boundaries.
This classmethoduseAnchoringBounds()The method accepts a boolean value, if true is passed to this method, the current matcher will use anchoring bounds; if false is passed to this method, it will use non-fixed bounds.
import java.util.Scanner; import java.util.regex.Matcher; import java.util.regex.Pattern; public class Trail { public static void main( String args[] ) { //Read string value Scanner sc = new Scanner(System.in); System.out.println("Enter input string"); String input = sc.nextLine(); //Regular expression to find numbers String regex = ".*\\d+.*"; //Compile regular expression Pattern pattern = Pattern.compile(regex); //Print regular expression System.out.println("Compiled regular expression: ");+pattern.toString()); //Retrieve matcher object Matcher matcher = pattern.matcher(input); matcher.useAnchoringBounds(false); boolean hasBounds = matcher.hasAnchoringBounds(); if(hasBounds) { System.out.println("Current matcher uses anchoring bounds); } else { System.out.println("Current matcher uses non-anchoring bounds); } } }
Output result
Enter input string sample Compiled regular expression: .*\d+.* Current matcher uses non-anchoring bounds

Output result
Match found Has anchoring bounds: false
