getResource puts a leading / before the disk name

问题:

The following gives a leading slash before the disk name. How can I avoid that?

String pngpath = getClass().getResource("/resources/lena.png").getPath();
System.out.println("pngpath = "+pngpath);

Gives:

pngpath = /C:/Users/jgrimsdale/Documents/NetBeansProjects/HelloCV/build/classes/resources/lena.png

回答1:

Use:

String pngpath = getClass().getResource("/resources/lena.png").getFile();
File file = new File(pngpath);
System.out.println(file.getAbsolutePath());

回答2:

A constructor of File(uri) or File(string) helps to get file object from system dependent path string or URI object.

It is a solution to using the Java Library.

System.out.println(new File("/C:/Users/jgrimsdale").toString())

回答3:

you can do this using this code.

System.out.println("pngpath = "+pngpath.substring(1,pngpath.length()));
