Usage

From source file:Main.java

public static void main(String[] args) {

    String s = "java2s.com 1 + 1 = 2.0 ";

    Scanner scanner = new Scanner(s);

    // check if next token is "java"
    System.out.println(scanner.hasNext("java"));

    // find the last match and print it
    System.out.println(scanner.match());

    System.out.println(scanner.nextLine());

    scanner.close();/*from   w w  w.j av  a  2  s .c om*/
