Java IO Basics@author IxenosSummary: Creating files, file filters, stream classifications, flow structures, common streams, using file streamsHow to create a file #当我们调用File类的构造器时, you simply create a file object at run time instead of creating one in the file system. The file class can represent a directory or file that exists in the filesystem, or it can indicate a#File. Separator is a cross-platfor

PrefaceThe previous chapters have introduced all paired (input and output) byte streams in the Java IO Package, and this chapter describes some of the remaining byte streams, including: Linenumberinputstream, Sequenceinputstream, StringBufferInputStream. In JDK8 's version, only the middle sequenceinputstream were not discarded,
