import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.InputStream;

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

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

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

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

                // read the byte and convert the integer to character
                char c = (char)bis.read();

                // print the characters
                System.out.println("Char: "+c);;
            }
        } catch(Exception e) {
            // if any I/O error occurs
            e.printStackTrace();
        } finally {
            // releases any system resources associated with the stream
            if(inStream!=null)
                inStream.close();
            if(bis!=null)
                bis.close();
        }
    }
}

假设test.txt内容如下：

ABCDE

输出结果为：

Char: A
Char: B
Char: C
Char: D
Char: E
