public class CharArrayReadermark {

    public static void main(String[] args) throws IOException {
        char buf[] = { 'a', 'b', 'c', 'd' };
        CharArrayReader charArrayReader = 
                      new CharArrayReader(buf);

        int readAheadLimit = 1;
        charArrayReader.mark(readAheadLimit);

        System.out.println("Successfully mark");
