Usage

From source file:Main.java

public static void main(String args[]) {
    String candidateString = "This is a test. This is another test.";
    Pattern p = Pattern.compile("test");
    Matcher matcher = p.matcher(candidateString);

    matcher.find();//from w  w w . j av a  2s .c om
    int endIndex = matcher.end();
    System.out.println(candidateString);
    System.out.println(endIndex);

}

From source file:MainClass.java

public static void main(String args[]) {
    String output = "";
    Pattern p = Pattern.compile("\\d");
    Matcher m1 = p.matcher("01234");

    while (m1.find()) {
        System.out.println("\t\t" + m1.group());
    }/*  w w  w  . j a  v  a2 s.co m*/
    m1.reset("56789");
    System.out.println("After resetting the Matcher");
    while (m1.find()) {
        System.out.println("\t\t" + m1.group());
    }
}

From source file:Test.java

public static void main(String[] args) {
    Pattern p = Pattern.compile("([\\w\\s]+) word");
    Matcher m = p.matcher("Could you test a phrase with some word");
    while (m.find()) {
        System.err.println(m.group(1));
        System.err.println(m.group());
    }//from w  w  w.  j a  va 2  s .  com
}

From source file:Main.java

    System.out.println(word);// ww  w.j a  va  2 s.  c  o  m
}

From source file:MainClass.java

public static void main(String args[]) {
    // Match lowercase words.

    Matcher mat = pat.matcher("www.java2s.com.");

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

From source file:Main.java

    int mIdx = 0;
    while (m.find()) {
        for (int groupIdx = 0; groupIdx < m.groupCount() + 1; groupIdx++) {
            System.out.println("[" + mIdx + "][" + groupIdx + "] = " + m.group(groupIdx));
        }//from w w  w  .  java 2  s.c  om
        mIdx++;
    }
}

From source file:MainClass.java

public static void main(String args[]) {
    Pattern p = Pattern.compile("\\d");
    Matcher matcher = p.matcher("5");
    boolean isOk = matcher.matches();
    System.out.println("original pattern matches " + isOk);

    // recycle the pattern
    String tmp = p.pattern();//w w  w. ja  va 2  s.  c om
    Pattern p2 = Pattern.compile(tmp);
    matcher = p.matcher("5");
    isOk = matcher.matches();
    System.out.println("second pattern matches " + isOk);
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    Pattern punct = Pattern.compile("\\G\\p{Punct}");

    Matcher mat = punct.matcher("this is a test 999");

    int i = 0;//from ww  w .j a v a 2s .c om
    while (matcher.find()) {
        ++i;
    }
    System.out.printf("Matched %d times%n", i);
}

From source file:MainClass.java
