java - URL.getRef() 和 URI.getFragment() 是一样的吗？

Question

URL.getRef() 和 URI.getFragment() 是一样的吗？

如果不是，它们有何不同？

运行下面的测试时，结果是一样的:

String url = "http://c.b.a.com:1234/path?p1=1&p2=2#somewhere";
System.out.println(new URL(url).getRef());
System.out.println(new URI(url).getFragment());

输出:

somewhere
somewhere

Answer 1

是的。他们是一样的东西。 javadoc对于 URL 说:

A URL may have appended to it a "fragment", also known as a "ref" or a "reference". The fragment is indicated by the sharp sign character "#" followed by more characters.
