This Example describes the way to retrieve the String using regular expression. For this we are going to make program named Reset. java. The steps involved in program Reset. java are described below:-
String regex = ("\\w.+"):- Creating expression for text. Here "\\w" means to match any alphanumeric character.
Pattern p = Pattern.compile(regex):- Creating a pattern object and compiles the given regular expression into a pattern.
String text = "Roseindia.net Rohini":- Declaring text which is to be reset by the matcher.
Matcher m = p.matcher(text):- Creates a matcher for matching the given input against pattern p.
m.find():- This is the method of matcher class which is used for finding the next subsequence of the input sequence and it usually returns a boolean value.
m.reset():- This is the method of the class Matcher which is used to reset the matcher.
Output of the program:-
|Text before resetting the Matcher is: Roseindia.net Rohini
Text after resetting the Matcher is: Roseindia.net Rohini
