package bao5;
import java.io.*;
public class Text5
{
    public static void main(String[] args)
    {
        //缓存的流
        //匿名对象
        try 
        {
            BufferedWriter bw=new BufferedWriter(new FileWriter("d:/test1.txt",true));
            bw.write("测试缓存语句");
            bw.close();
            System.out.println("写入完成");
            //读
            BufferedReader br=new BufferedReader(new FileReader("d:/test1.txt"));
            String str=br.readLine();
            br.close();
            System.out.println(str);
        } 
        catch (IOException e) 
        {
            e.printStackTrace();
        }
