Advances this scanner past the current line and returns the input that was skipped.

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);

    // find a string of world, with horizon of 10
    System.out.println(scanner.findWithinHorizon("com", 10));

    // find a string of world, with horizon of 20
    System.out.println(scanner.findWithinHorizon("=", 20));

    // print the rest of the string
    System.out.println(scanner.nextLine());

    scanner.close();/*from  ww w.jav a  2s . c  o  m*/
