Any I/O operation can be accomplished with the InputStream and OutputStream classes. These classes are like atoms: you can build anything with them, but they are very basic building blocks.The InputStream and OutputStream classes only give you access to the raw bytes of the connection. It’...
FileInputStream是InputStream的一个子类,实现了对文件的读。 A FileInputStream obtains input bytes from a file in a file system. What files are available depends on the host environment. FileInputStream is meant for reading streams of raw bytes such as image data. For reading streams of characte...
对象流操作类有ObjectInputStream和ObjectOutputStream,这两个类又分别实现了ObjectInput和ObjectOutput接口,同时ObjectInput和ObjectOutput是DataInput和DataOutput的子接口。 ObjectInput 扩展 DataInput 接口以包含对象的读操作。DataInput 包括基本类型的输入方法;ObjectInput 扩展了该接口,以包含对象、数组和 String 的输出...
处理上面显示的两个问题的最简单方法是在InputStream.transferTo(OutputStream)方法的Javadoc注释中表达的方法是在try-with-resources语句中实例化源InputStream和目标OutputStream。 下一个代码清单中显示了一个示例。 StreamsTransfer.java:使用InputStream.transferTo(OutputStream) package dustin.examples.iostreams; import...
Output: If file is not available in project root folder. when the file is present: Handling Exceptions Several exceptions in the java.io package might occur when you are working with files and streams. A FileNotFound exception occurs when you try to create a stream or file object using a ...

The behavior for the case where the input and/or output stream is asynchronously closed, or the thread interrupted during the transfer, is highly input and output stream specific, and therefore not specified. If an I/O error occurs reading from the input stream or writing to the output ...
ObjectInputStream中的方法大多依赖于bin变量. 比如: 构造方法中会创建 binbin 他是DataInputStream的内部类 BlockDataInputStreamBlockDataInputStream内部还有两个变量分别是DataInputStream 和PeekInputStream 其中的PeekInputStream也是内部类 输入流有两种模式:在默认模式下,输入数据以与DataOutputStream相同的格式写入;在...
