Usage

From source file:ReplaceExample.java

public static void main(String args[]) {
    String regex = "(\\w)(\\d)(\\w+)";
    Pattern pattern = Pattern.compile(regex);

    String candidate = "X99SuperJava";

    String tmp = matcher.replaceAll("$33");

    System.out.println("REPLACEMENT: " + tmp);
    System.out.println("ORIGINAL: " + candidate);
}

From source file:Main.java

    System.out.println(tmp);//from w w w. ja va 2  s .c o  m
}

From source file:Main.java

    // Now create matcher object.
    Matcher m = r.matcher(line);
