java - "resolve"路径到底意味着什么？

Question

我现在已经阅读了许多有关 Java somePath.resolve( someOtherPath ) 使用的文章，但我找不到准确的定义以及有用的示例，确切地说 “解析”路径的意思。每个人似乎都假设你知道。 有人可以非循环地定义它吗？或者给我指出一个(非循环)解释器？

Answer 1

这个问题的答案在 documentation 中定义。 ，它很好地表明了该方法的作用。

Converts a given path string to a Path and resolves it against this Path in exactly the manner specified by the resolve method. For example, suppose that the name separator is "/" and a path represents "foo/bar", then invoking this method with the path string "gus" will result in the Path "foo/bar/gus".

换句话说，如果路径C:/Program Files/Foo/是当前Path并且Bar存在于中Foo，您可以执行以下操作:

Path parent = Paths.get("C:", "Program Files", "Foo");

Path child = parent.resolve("Bar");
