缓存输入输出流

1）将文件读入内存：

将BufferedInputStream与FileInputStream相接

 FileInputStream in=new  FileInputStream( “file1.txt ” );

 BufferedInputStream bin=new  BufferedInputStream( in); 

 

2）将内存写入文件：

将BufferedOutputStream与 FileOutputStream相接

FileOutputStreamout = new FileOutputStream(“file1.txt”);

BufferedOutputStream  bin = new BufferedInputStream(out);

3）键盘输入流读到内存 将BufferedReader与标准的数据流相接  InputStreamReader sin = new InputStreamReader (System.in) ； BufferedReader bin = new BufferedReader(sin);
