Create URL from a String

Question

It is a very basic question. But i am unable to find an answer in Java documentation and unable to test it as well since i don't know if such method exist or not.

I might receive a URL String which could be

http://www.example1.com

or

http://www.example1.com/

and then i will get resource path which might start with /api/v1/status.xml or it would be like api/v1/status.xml

I was looking at URL class and I can handle the first part i.e. fetching the hostURL to make it an HTTPS or HTTP request. The problem is appending the resource path. either i have to check it manually if the first letter is / or not. I was wondering if this functionality is already in some class or not.

Is this similar to what you're looking for? It might be helpful: stackoverflow.com/questions/1861620/… — MikeB

URL url = new URL(yourUrl, "/api/v1/status.xml");

According to the javadocs this constructor just appends whatever resource to the end of your domain, so you would want to create 2 urls:

URL domain = new URL("http://example.com");
URL url = new URL(domain + "/files/resource.xml");

What if URL url = new URL(domain + "files/resource.xml"); ? MalformedURL ? ... what if domain=www.example.com/ and new URL (domain + "/files/resources.xml"); ... again malformed

I've seen many times where an application first checks the URL string for if (domain.endsWith("/")) {domain = domain.substring(0, domain.length()-1);} For all other problems, catch MalformedURLException and handle from there.

I'm getting MalformedURLException just because the protocol is not "http". OMG /facepalm

using java.net.URI is the better way
