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 O
OutputStream objects are usually obtained from other objects.For example, the Socket class contains a method called getOutputStream. Calling the getOutputStream method will return an OutputStream object that will be used to write to the socket. Other output streams are obtained by different means....
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...
Java 8 中的 Streams API 详解 为什么需要 Stream Stream 作为 Java 8 的一大亮点,它与 java.io 包里的 InputStream 和 OutputStream 是完全不同的概念。它也不同于 StAX 对 XML 解析的 Stream,也不是 Amazon Kinesis 对大数据实时处理的 Stream。Java 8 中的 Stream 是对集合(Collection)对象功能的增强,它...
1、FileInputStream、FileOutputStream(字节流) 字节流的方式效率较低,不建议使用 publicclassIOTest{publicstaticvoidmain(String[]args)throwsIOException{Filefile=newFile("D:/test.txt");write(file);System.out.println(read(file));}publicstaticvoidwrite(Filefile)throwsIOException{OutputStreamos=newFileOutput...

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 ...
