Usage

From source file:Main.java

public static void main(String args[]) {
    Pattern pat = Pattern.compile("\\b\\w+@XYZ\\.com\\b");

    Matcher mat = pat.matcher("t@XYZ.com\n" + "a@XYZ.com\n" + "n@XYZ.com");

    while (mat.find())
        System.out.println("Match: " + mat.group());
}

From source file:Main.java

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

    CharSequence inputStr = "a b c b";
    Matcher matcher = pattern.matcher(inputStr);
    boolean matchFound = matcher.find();
    System.out.println(matchFound);

    String match = matcher.group();
    System.out.println(match);/*from www  .  jav a2 s.  com*/

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