程序清单：FileStream.java

import java.io.*;public class FileStream{public static void main(String[] args){File f = new File("hello.txt"); try{FileOutputStream out = new FileOutputStream(f);byte buf[]="www.it315.org".getBytes();out.write(buf);out.close();}catch(Exception e){System.out.println(e.getMessage());}try{FileInputStream in = new FileInputStream(f);byte [] buf = new byte[1024];int len = in.read(buf);System.out.println(new String(buf,0,len));}catch(Exception e){System.out.println(e.getMessage());}}}
