To add to the answers already mentioned here, if you have a generic class that handles, say, HTTP calls, it maybe useful to pass Class as part of the constructor.
To give a little more detail, this happens because Java cannot infer the Class during runtime with just T. It needs the actual solid class to make the determination.
So, if you have something like this, like I do:
class HttpEndpoint implements IEndpoint
you can allow the inheriting code to also send the class, since at that point is it clear what T is.
public HttpEndpoint(String baseurl, String route, Class cls) {
this.baseurl = baseurl;
this.route = route;
this.cls = cls;
}
inheriting class:
public class Players extends HttpEndpoint {
public Players() {
super("http://127.0.0.1:8080", "/players", Player.class);
}
}
while not entirely a clean solution, it does keep the code packaged up and you don't have to Class between methods.
