Re this: 重新这样：
While using select query all three contents are fetched in same variable.
All three would be assigned to an instance of Elements which is a type of ArrayList so, in order to interrogate each of these three elements you could 所有这三个Elements都将分配给一个ArrayList类型的Elements实例，因此，为了询问这三个元素，您可以
- Iterate over the ArrayList:
for (Element element : elements) { ... }遍历ArrayList： for (Element element : elements) { ... } - Select entries by position:
elements.get(0),elements.get(1)etc按位置选择条目： elements.get(0)，elements.get(1)等 - Iterate over
Elementsusingprev()andnext()使用prev()和next()遍历Elements - Select the
first()orlast()选择first()或last() - Use a visitor pattern to
traverse()theElements使用访问者模式traverse()Elements - Get the
textof each of the entries:elements.eachText()获取每个条目的text：elements.eachText()

You can get an Elements object using select method. 您可以使用select方法获取Elements对象。 As @glyching mentioned, you can traverse it. 如@glyching所述，您可以遍历它。 I created test code using forEach like as below. 我使用forEach创建了测试代码，如下所示。
public void test() {
Document doc = Jsoup.parse("<html><body><div class=\"content-section generic-section\">contents1</div><div class=\"content-section generic-section\">contents2</div><div class=\"content-section generic-section\">contents3</div></body></html>");
// get div elements
Elements elements = doc.select("div.content-section.generic-section");
// display "contents1" "contents2" "contents3"
elements.forEach(element -> System.out.println(element.text()));
}
