[java] Pass a local file in to URL in Java

How do I create a new URL object using a local file, for the purpose of unit tests?

have a look here for the full syntax: http://en.wikipedia.org/wiki/File_URI_scheme for unix-like systems it will be as @Alex said file:///your/file/here whereas for Windows systems would be file:///c|/path/to/file

File myFile=new File("/tmp/myfile");
URL myUrl = myFile.toURI().toURL();

Using Java 7:

Paths.get(string).toUri().toURL();

However, you probably want to get a URI. Eg, a URI begins with file:/// but a URL with file:/ (at least, that's what toString produces).

You can also use

[AnyClass].class.getResource(filePath)

new File("path_to_file").toURI().toURL();

new URL("file:///your/file/here")

I tried it with Java on Linux. The following possibilities are OK:

file:///home/userId/aaaa.html
file:/home/userId/aaaa.html
file:aaaa.html  (if current directory is /home/userId)

not working is:

file://aaaa.html
