Java IO学习基础之读写文本文件

<script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"> </script> Java的IO操作都是基于流进行操作的，为了提高读写效率一般需要进行缓冲。 简单的示例程序如下： /** * 读出1.txt中的内容，写入2.txt中 * */ import java.io.*; public class ReadWriteFile{ public static void main(String[] args){ try{ File read = new File("c:/1.txt"); File write = new File("c:/2.txt"); BufferedReader br = new BufferedReader( new FileReader(read)); BufferedWriter bw = new BufferedWriter( new FileWriter(write)); String temp = null; temp = br.readLine(); while(temp != null){ //写文件 bw.write(temp " "); //只适用Windows系统 //继续读文件 temp = br.readLine(); } bw.close(); br.close(); }catch(FileNotFoundException e){ //文件未找到 System.out.println (e); }catch(IOException e){ System.out.println (e); } } }
