Usage

From source file:Main.java

public static void main(String args[]) {
    Pattern p = Pattern.compile("test", Pattern.CASE_INSENSITIVE);
    String candidateString = "Test.";
    Matcher matcher = p.matcher(candidateString);
    matcher.find(0);//from w  ww. j av a2  s.co  m
    System.out.println(matcher.group());

}

From source file:MatcherGroupCountExample.java

public static void main(String args[]) {
    Pattern p = Pattern.compile("B(ond)");

    String candidateString = "My name is Bond. James Bond.";
    Matcher matcher = p.matcher(candidateString);

    int numberOfGroups = matcher.groupCount();
    System.out.println("numberOfGroups =" + numberOfGroups);

}

From source file:Main.java

public static void main(String[] args) {
    String patternStr = "b";

    boolean matchFound = matcher.find();
    System.out.println(matchFound);

    String match = matcher.group();
    System.out.println(match);/*from w ww . j  av a 2 s.com*/

    int start = matcher.start();
    int end = matcher.end();
    System.out.println(start);
    System.out.println(end);
    matchFound = matcher.find();
}
