import java.io.ByteArrayInputStream;
import java.io.IOException;

public class Demo {
    public static void main(String[] args) throws IOException {
        byte[] buf = {65, 66, 67, 68, 69};
        ByteArrayInputStream bais = null;

        try {
            // create new byte array input stream
            bais = new ByteArrayInputStream(buf);

            // print bytes
            System.out.println("Byte read "+ bais.read());
            System.out.println("Byte read "+ bais.read());
            System.out.println("Byte read "+ bais.read());
            System.out.println("Byte read "+ bais.read());
            System.out.println("Byte read "+ bais.read());

            System.out.println("Reset() invocation");

            // reset() invocation
            bais.reset();
            System.out.println("Byte read "+ bais.read());
            System.out.println("Byte read "+ bais.read());

        } catch(Exception e) {
            // if I/O error occurs
            e.printStackTrace();
        } finally {
            if(bais!=null)
                bais.close();
        }
    }
}

输出结果为：

Byte read 65
Byte read 66
Byte read 67
Byte read 68
Byte read 69
Reset() invocation
Byte read 65
Byte read 66
