推荐答案

a href =http://docs.oracle.com/javase/6/docs/api/java/net/URL.html =noreferrer> java.net.URL 和/或 java.net.URLConnection 。

You can make use of java.net.URL and/or java.net.URLConnection.

URL url = new URL("http://stackoverflow.com");

try (BufferedReader reader = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"))) {
    for (String line; (line = reader.readLine()) != null;) {
        System.out.println(line);
    }
}

另请参阅 Oracle的简单教程。这是一个有点冗长。要使用较少详细的代码，您可以考虑 Apache HttpClient

Also see the Oracle's simple tutorial on the subject. It's however a bit verbose. To end up with less verbose code, you may want to consider Apache HttpClient instead.

顺便说一下：如果你的下一个问题是如何处理HTML结果？，那么答案是使用HTML解析器。不，不要使用正则表达式。。

By the way: if your next question is "How to process HTML result?", then the answer is "Use a HTML parser. No, don't use regex for this.".
