Usage

From source file:Main.java

public static void main(String[] args) {
    String str = "_6654_1";

    Pattern p = Pattern.compile("_(\\d+)_1");
    Matcher m = p.matcher(str);
    if (m.matches())
        System.out.println(m.group(1)); // prints 6654
}

From source file:Main.java

public static void main(String[] args) {
    String s = "this is a good example with 234 songs";

    Pattern p = Pattern.compile("this is a (.*?) example with (\\d+) songs");
    Matcher m = p.matcher(s);
    if (m.matches()) {
        String kind = m.group(1);
        String nbr = m.group(2);//w  w  w .ja v a2 s  . co m

        System.out.println("kind: " + kind + " nbr: " + nbr);
    }
}

From source file:MainClass.java

public static void main(String args[]) {
