public class Demo {
    public static void main(String[] args) {      CharArrayReader car = null;
        char[] ch = {'A', 'B', 'C', 'D', 'E'};

        try {
            // create new character array reader
            car = new CharArrayReader(ch);

            int value = 0;

            // read till the end of the stream
            while((value = car.read())!=-1) {

                // convert integer to char
                char c = (char)value;

                // print characters
                System.out.print(c + "; ");

                // skip single character
                long l = car.skip(1);
                System.out.println("Characters Skipped : "+l);
            }

        } catch(IOException e) {
            // if I/O error occurs
            e.printStackTrace();
        } finally {
            // releases any system resources associated with the stream
            if(car!=null)
                car.close();
        }
    }
}

输出结果为：

A; Characters Skipped : 1
C; Characters Skipped : 1
E; Characters Skipped : 0
