在Java7之前,我们一直用File来操作文件,使用构建的File对象进行文件操作,不过相应的API效率不是很高,所以在Java7之后引入新的文件操作类。 import java.nio.file.DirectoryStream;import java.nio.file.FileSystem;import java.nio.file.FileSystems;import java.nio.file.Files;import java.nio.file.Path;import java...

javaFile源码理解,探索File路径 1.方法:newFile(path); 我们知道根据输入的路径path的不同,File可以根据path的不同格式,来访问文件。那么,path的形式有几种呢? 根据源码 可以知道,输入的路径path其实是在类FileSystem中处理的。FileSystem是一个抽象类,所以,其实是在其实现类WinNTFileSystem中处理。
