import java.io.BufferedInputStream;

import java.io.IOException;
import java.io.InputStream;

public class Demo {
    public static void main(String[] args) throws Exception {
        InputStream is =null;
        BufferedInputStream bis = null;

        try {
            // open input stream test.txt for reading purpose.
            is = new FileInputStream("d:/test.txt");

            // input stream is converted to buffered input stream
            bis = new BufferedInputStream(is);

            // read until a single byte is available
            while(bis.available()>0) {

                // skip single byte from the stream
                bis.skip(1);

                // read next available byte and convert to char
                char c = (char)bis.read();

                // print character
                System.out.print(" " + c);
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            // releases resources from the streams
            if(is!=null)
                is.close();
            if(bis!=null)
                bis.close();
        }
    }
}

假设test.txt内容如下：

ABCDE

输出结果为：

 B D ￿
