java io

最近看了一下Java io

具体细节不详细描述  推荐一篇文章写的不错，对io简述的比较全面，不过不是很细致  http://www.cnblogs.com/rollenholt/archive/2011/09/11/2173787.html

 

一下描述一下java io中的主要操作类

 

字节流

InputStream in = new FileInputStream(new File(path));

OutputStream out = new FileOutputStream(new File(path));

 

字符流

Reader reader = new FileReader(new File(path));

Writer writer = new FileWriter(new File(path));

 

字节转字符流

Reader reader = new InputStreamReader(new FileInputStream(new File(path)));

Writer writer = new OutputStreamWriter(new FileOutputStreamWriter(new File(path)));

 

内存操作流

ByteArrayInputStream in = new ByteArrayInputStream(new byte[10]);

ByteArrayOutputStream out = new ByteArrayOutputStream();

 

管道流

PipedInputStream in = new PipedInputStream();

PipedOutputStream out = new PipedOutputStream();

 

Scanner 类

Scanner sca = newScanner(System.in);

 

合并流

SequenceInputStream in = new SequenceInputStream（new FileInputStream(new File(path)) ,new FileInputStream(new File(path)) ）;

OutputStream output = new FileOutputStream(new File(path));

 

文件压缩

ZipOutputStream

ZipInputStream

 

序列话对象

序列化对象又两种方式 

1、java自带的要序列化的对象需要实现implements Serializable

2、使用第三方包 xStream.jar  序列化的对象不需要实现或者继承其他类

 

其他操作类

回退流  PushBackInputStream

数据操作流 DataOutputStream、DataInputStream类

BufferedReader

RandomAccessFile
