如何從兩個(gè)絕對路徑(或URL)構(gòu)造Java中的相對路徑？給定兩條絕對路徑。/var/data/stuff/xyz.dat/var/data如何創(chuàng)建使用第二條路徑作為基礎(chǔ)的相對路徑？在上面的例子中，結(jié)果應(yīng)該是：./stuff/xyz.dat

String path = "/var/data/stuff/xyz.dat";String base = "/var/data";String relative = new File(base).toURI(). relativize(new File(path).toURI()).getPath();// relative == "stuff/xyz.dat"
java.nio.file.Path#relativize

import java.nio.file.Path;import java.nio.file.Paths;public class Test {
public static void main(String[] args) {
Path pathAbsolute = Paths.get("/var/data/stuff/xyz.dat");
Path pathBase = Paths.get("/var/data");
Path pathRelative = pathBase.relativize(pathAbsolute);
System.out.println(pathRelative);
}}stuff/xyz.dat
