Java Use URI builder?

I have bellow url :

http://www.example.com/api/Video/GetListMusicRelated/0/0/null/105358/0/0/10/null/null

This section is Fixed and unchangeable:

http://www.example.com/api/Video/GetListMusicRelated/

I set parameter to this url like bellow :

 http://www.example.com/api/Video/GetListMusicRelated/25/60/jim/105358/20/1/5/null/null

OR :

http://www.example.com/api/Video/GetListMusicRelated/0/0/null/105358,5875,85547/0/0/10/null/null

How I can write for this url a url builder ?

Solution

  • If you want to create an UrlBuilder using the builder pattern, it could be done like this:

    public class UrlBuilder {
    private final String root;
    private int myParam1;
    private String myParam2;

    public UrlBuilder(final String root) {
        this.root = root;
    }

    public UrlBuilder myParam1(int myParam1) {
        this.myParam1 = myParam1;
        return this;
    }

    public UrlBuilder myParam2(String myParam2) {
        this.myParam2 = myParam2;
        return this;
    }

    public URL build() throws MalformedURLException {
        return new URL(
            String.format("%s/%d/%s", root, myParam1, myParam2)
        );
    }
}

    Then you will be able to create your URL as next

    URL url = new UrlBuilder("http://www.example.com/api/Video/GetListMusicRelated")
    .myParam1(25)
    .myParam2("jim")
    .build();

    NB: This only shows the idea, so I used fake parameter's name and incorrect number of parameters, please note that you are supposed to have 6 parameters and set the proper names.
