Resets this matcher and then attempts to find the next subsequence of the input sequence that matches the pattern, starting at the specified index.

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);
    System.out.println(matcher.group());

    String candidateString = "Java. java JAVA jAVA";

    Matcher matcher = p.matcher(candidateString);

    // display the latter match
    System.out.println(candidateString);
    matcher.find(11);
    System.out.println(matcher.group());

    // display the earlier match
    System.out.println(candidateString);
    matcher.find(0);//  w ww.  j av a  2s . com
