I have a URL:
我有一个网址：
URL url=new URL("http://www.abc.com/aa/bb/cc/file.html");
and a relative path:
和一个相对路径：
String relativePath="../file2.html"; //maybe is "/file3.html"
I want to get http://www.abc.com/aa/bb/file2.htmlusing variable urland relativePath
我想http://www.abc.com/aa/bb/file2.html使用变量url和relativePath

Try operating winth the class URIinstead of the URL.
To get the URI from your URL:
要从您的 URL 获取 URI：
java.net.URI anURI=url.toUri();
Then, to resolve the relative URI:
然后，要解析相对 URI：
URI resultURI=anURI.resolve(relativePath);
And at last, to get an URL type use de method toUrl()of the URI result variable, and you've got it.
最后，要获取 URL 类型，请使用URI 结果变量的方法toUrl()，你就得到了它。

If you want to build an URL pointing to a relative file, you can use:
如果要构建指向相对文件的 URL，可以使用：
URL url = new URL(new URL("file:"), "./myLocalFile.txt");

When building relative URL, keep in mind that the base is path to current package, not file. I mean: the referer file is in .../myProject/src/pckg/javafile.javaand the referated file is in .../myProject/some-other/nice.file, then the relative reference should look like this:
在构建相对 URL 时，请记住基础是当前包的路径，而不是文件。我的意思是：引用文件在.../myProject/src/pckg/javafile.java，被引用文件在.../myProject/some-other/nice.file，那么相对引用应该是这样的：
URL url = new URL(new URL("file:"), "./../some-other/nice.file");
and this works for me as well:
这也适用于我：
URL url = new URL("file:./../some-other/nice.file");

This worked for my codeURL url=Myclass.class.getResource("/com/fnf/si/DepAcctInq_V02.wsdl");
这适用于我的代码URL url=Myclass.class.getResource("/com/fnf/si/DepAcctInq_V02.wsdl");
