    Please refer to the Scanner API page to review the available methods. You'll see that nextChar() isn't there.

    Hello.
    Instead of nextChar(), try nextByte() and see if it fulfills your requirements.

    or...since there's no nextChar(), look for findWithinHorizon such as

    To find within the next count characters : ScannerFileJava Tutorial


    p/s: learn to look for javadoc, at least google for used method on java.util.Scanner. this will save your time.
