How to replace File.listFiles(FileFilter filter) with nio in Java 7?

I have some file I/0 traversal code written in Java 6, trying to move it the New I/O in Java 7 but I cannot find any replacement for this kind of stuff. File[] files = dir.listFiles(AudioFileFilter.getInstance()); Namely, no way to filter paths only files, and it returns list of files so I would then have to convert each file to path (file.toPath) if I wanted to limit the use of File in methods it calls, which seems rather laborious. I did look at FileVisitor but this does not seem to allow you to control how the the tree is traversed so I don' think it will work for me. So how much of a

Using Java 7 SDK features in Java 6

问题 I am interested in using some of the NIO2 features in the Java 7 SDK if available (specifically, the file system watchers), however I do not want to compile my classes for Java 7 and exclude Java 6 runtimes. Mostly because I want retain compatibility with Mac OS X, and also because I don’t want to force my users to upgrade. Is this possible? What is the best way to do it? Any links or examples? Here are some ways I can imagine: compiling a class file with a different compiler and loading it

Find the directory for a FileStore

问题 I'm trying to find a way to detect when a flash drive has been plugged into my computer. So far, the solution I found was to poll FileSystem#getFileStores for changes. This does indeed tell me when the flash drive has been inserted, but as far as I can tell there is no way to retrieve the location for it. FileStore#type and FileStore#name both seem highly unreliable as their return value is implementation specific, but they appear to be the only methods that might return any relevant

java.nio.file.Path for a classpath resource

由 匆匆过客 提交于 2019-11-27 10:38:07
Is there an API to get a classpath resource (e.g. what I'd get from Class.getResource(String) ) as a java.nio.file.Path ? Ideally, I'd like to use the fancy new Path APIs with classpath resources. This one works for me: return Paths.get(ClassLoader.getSystemResource(resourceName).toURI()); Guessing that what you want to do, is call Files.lines(...) on a resource that comes from the classpath - possibly from within a jar. Since Oracle convoluted the notion of when a Path is a Path by not making getResource return a usable path if it resides in a jar file, what you need to do is something like
