However, you\u2019ll always want to consider your end goal and any particular constaints before makeing a decision. For example, it\u2019s always best to try and use the native Java classes rather than third-parties, but sometimes the HttpClient just makes more sense. If you\u2019re planning to extract with JSoup, then you would like choose that route. It all depends on what you\u2019re trying to accomplish.<\/p>\n<\/body>","protected":false},"excerpt":{"rendered":"
