java - 在哪里使用java.nio.file.Path类的resolve()和relativize()方法？

Path p1 = Paths.get("/Users/jack/Documents/text1.txt");
Path p2 = Paths.get("/Users/jack/text2.txt");
Path result1 = p1.resolve(p2);
Path result2 = p1.relativize(p2);

System.out.println("result1: "+result1);
System.out.println("result2: "+result2);

输出值

result1: /Users/jack/text2.txt
result2: ../../text2.txt

我不明白resolve()和relativize()的工作原理？
result1和result2的实际用途是什么？

最佳答案

这些是我代码库中的代码段，可帮助您了解resolve()方法的使用

private File initUsersText() throws Exception
{
    Path dir = testdir.getPath().toRealPath();
    FS.ensureDirExists(dir.toFile());
    File users = dir.resolve("users.txt").toFile();

    writeUser( users );
    return users;
}


private File initUsersText() throws Exception
{
    Path dir = testdir.getPath().toRealPath();
    FS.ensureDirExists(dir.toFile());
    File users = dir.resolve("users.txt").toFile();

    writeUser( users );
    return users;
}

这些是使用relativize()的示例

public ScopePath pathToClassName(Path file) {
    if (!isValidClass(file))
        return null;

    Path relativePath = root.relativize(root.resolve(file));
    String withoutExtension = removeExtension(relativePath.toString());
    return new ScopePath(withoutExtension.replace(File.separator, "."));
}


private String getRelativePath(Path p) {
    String relativePath = packageDir.relativize(p)
            .toString();

    if (File.separator.equals("\\")) {
        relativePath = relativePath.replace("\\", "/");
    }

    return relativePath;
}
