ByteArrayOutputStream 类:向内存缓冲区的字节数组中写数据。 FileOutputStream 类:向文件中写数据。 PipedOutputStream 类:连接到一个 PipedlntputStream(管道输入流)。 ObjectOutputStream 类:将对象序列化。 1. 2. 3. 4. 5. 6. 7. 利用OutputStream 类的方法可以从流中写入一个或一批字节。

ByteArrayOutputStream 是字节数组输出流。写入ByteArrayOutputStream的数据被写入一个 byte数组。缓冲区会随着数据的不断写入而自动增长。可使用 toByteArray() 和 toString() 获取数据。 PipedOutputStream 是管道输出流,它和PipedInputStream一起使用,能实现多线程间的管道通信。
ByteArrayInputStream bais =new ByteArrayInputStream(baos.toByteArray());//创建一个字节数组输入流对象,数据为之前输出流的数据ObjectInputStream ois = new ObjectInputStream(bais);/创建一个对象输入流对象(对字节数组输入流对象的一个包装)return ois.readObject();//返回输入流中的对象...
