java.util.regex.Matcher class represents the engine for executing various matching operations. This class has no constructor, and it can be usedmatches()
Method created by the class java.util.regex.Pattern/Get an object of this class.
Anchoring bounds are used for area matching, such as ^ and $. By default, the matcher uses anchoring bounds.
This classThe method'suseAnchoringBounds()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.
