问题 I'm trying to create an application to scrape content off of multiple pages on a site. I am using JSoup to connect. This is my code: for (String locale : langList){ sitemapPath = sitemapDomain+"/"+locale+"/"+sitemapName; try { Document doc = Jsoup.connect(sitemapPath) .userAgent("Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.21 (KHTML, like Gecko) Chrome/19.0.1042.0 Safari/535.21") .timeout(10000) .get(); Elements element = doc.select("loc"); for (Element urls : element) { System.out

问题 I was running a few tests with sockets, and I encountered some strange behavior: A ServerSocket will refuse connections after the 50th client Socket connects to it, even if that client socket is closed before the next one is opened, and even if a delay is added between connections. The following program is my experimental code, which in its current state, throws no exceptions and terminates normally. However, if the array size of Socket[] clients is increased beyond 50, any client sockets

问题 What is connection() in the following code? Code which I do understand completely if($user->connection($email,$password)){ } Let's assume connection() is pseudo-code.
