Assign String-Data to a URL-Object

Is it possible to assign string-data to a java.net.URL?

I'm using an API who's method only accept an URL-Parameter. But i already have the content.

String content = "some text data";
URL url = createURLWithContent(content);
MyApi.handleContent( url );

the createURLWithContent()-Method should create URL-object that containing the data from content, so when URL.getContent() is called, the String (or a Stream containing the String) is returned.

I think I've seen something like this years ago.

Write the content to a file then provide a file: URL, e.g.

public static URL createURLWithContent(String content) throws IOException {
    Path tempFile = Files.createTempFile("UrlContent", null);
    tempFile.toFile().deleteOnExit();
    Files.writeString(tempFile, content);
    return tempFile.toUri().toURL();
}

This will return a URL like this:

file:/C:/path/to/temp/UrlContent5767435257817348076.tmp

If your program is long-running, you should handle the deletion of the temporary file yourself, after the API call, rather than rely on deleteOnExit().

If you don't want the content on disk, you could alternatively implement your own in-memory URLStreamHandler, and specify it when creating the URL using the URL(String protocol, String host, int port, String file, URLStreamHandler handler) constructor. This is a lot more involved and beyond the scope of this answer.
