如何在Java 7 java.nio.file.Path中访问子文件/文件夹? [英] How to access a sub-file/folder in Java 7 java.nio.file.Path?
问题描述
Java 7引入了 java.nio.file .Path 作为java.io.File的可能替代。 / p>
使用文件,当我访问特定的文件时,我会这样做:
文件parent = new File(c:\\ tmp);
File child = new File(parent,child); //这次访问c:\ tmp \child
使用Path执行此操作的方法是什么?
我认为这样可行:
Path parent = Paths。获得( C:\\tmp);
Path child = Paths.get(parent.toString(),child);
但是调用 parent.toString()
似乎丑陋。有更好的方法吗?
使用 resolve
< 上的/ a>方法路径
。
此名称有两种方法。 一个需要一个相对路径
和另一个 字符串
。它使用 Path
作为父对象,并附加 String
或相对路径
相应。
路径父= Paths.get(c:\\ tmp );
Path child = parent.resolve(child);
Java 7 introduced java.nio.file.Path as a possible replacement for java.io.File.
With File, when I access a file under a specific, I would do:
File parent = new File("c:\\tmp");
File child = new File(parent, "child"); // this accesses c:\tmp\child
What's the way to do this with Path?
I supposed this will work:
Path parent = Paths.get("c:\\tmp");
Path child = Paths.get(parent.toString(), "child");
But calling parent.toString()
seems ugly. Is there a better way?
Use the resolve
method on Path
.
There are two methods with this name. One takes a relative Path
and the other a String
. It uses the Path
on which it is called as a parent and appends the String
or relative Path
appropriately.
Path parent = Paths.get("c:\\tmp");
Path child = parent.resolve("child");
