It's possible to prevent duplicated URL on Set?

URL come dynamically, so, I don't know what is the url that will come, it can come with and without bar on final. I need to add all url's on Set preventing adding the same URL. I know that bars on final make the URL different, but it's possible to prevent it on Set?

private var urlList: MutableSet<URL> = mutableSetOf()

要么

private var urlList: MutableSet<String> = mutableSetOf()

It is Kotlin, but sample in Java are welcome.

好的，这是操作方法（也许）

由于URL是最终的，因此您需要在URL上创建包装器类，并将URLWRapper的对象添加到您的集合中

public class URLWrapper {
  private URL url;
  public URLWrapper(URL url) {
    ...
  }
  public URL getURL() {...}
  public boolean equals(Object o) {
    if (!(o instanceof URLWrapper)) return false;
    return ((URLWRapper)o).getURL().sameFile(this.url);
  }
}

您应该测试sameFile-我实际上并不知道这在您感兴趣的所有情况下都行得通。但是，如果没有，那么您需要自己实现一个类似sameFile的方法。
