java - Java - 使用“/”作为第一个参数会引发 java.nio.file.InvalidPathException

Question

我正在尝试使用“/”作为第一个字符串参数和“test.txt”作为第二个字符串参数来获取路径。所需的输出是：“/test.txt”

Path pth = Paths.get("/", "test.txt");
System.out.println(pth);

运行程序后，我得到：

Exception in thread "main" java.nio.file.InvalidPathException: UNC path 
is missing sharename: /\test.txt
at sun.nio.fs.WindowsPathParser.parse(Unknown Source)
at sun.nio.fs.WindowsPathParser.parse(Unknown Source)
at sun.nio.fs.WindowsPath.parse(Unknown Source)
at sun.nio.fs.WindowsFileSystem.getPath(Unknown Source)
at java.nio.file.Paths.get(Unknown Source)
at be.bt.test.Test.main(Test.java:10)

我是 java 新手，我需要了解为什么 JVM 会抛出这个异常？

此致..
