如何添加運行時超時以防止出現java.net.SocketTimeoutException？

Question

所以我有一個程序從Yelp中提取商業信息並輸出。一切都編譯完成，並運行一段時間，直到它最終遇到java.net.SocketTimeoutException。我對這個問題做了一些研究，顯然這是網絡的一個問題，解決辦法是增加一個運行時間超時。這是事情，我不知道如何完成，也沒有如何將其實現到我的代碼。這是我得到的：

import java.util.ArrayList; 
import org.jsoup.Jsoup; 
import org.jsoup.nodes.Document; 
import org.jsoup.nodes.Element; 
import org.jsoup.select.Elements; 
import java.io.IOException; 
import java.util.Scanner; 

public class YelpScraper 
{ 
    public static void main(String[] args) throws IOException, Exception, RuntimeException 
    {   
     //Variables 
     String description; 
     String location; 
     int pages; 
     int parseCount = 0; 
     Document document; 

     Scanner keyboard = new Scanner(System.in); 

     //Perform a Search 
     System.out.print("Enter a description: "); 
     description = keyboard.nextLine(); 

     System.out.print("Enter a state: "); 
     location = keyboard.nextLine(); 

     System.out.print("How many pages should we scan? "); 
     pages = keyboard.nextInt(); 

     String descString = "find_desc=" + description.replace(' ', '+') + "&"; 
     String locString = "find_loc=" + location.replace(' ', '+') + "&"; 
     int number = 0; 

     String url = "https://www.yelp.com/search?" + descString + locString + "start=" + number; 
     ArrayList<String> names = new ArrayList<String>(); 
     ArrayList<String> address = new ArrayList<String>(); 
     ArrayList<String> phone = new ArrayList<String>(); 

     //Fetch Data From Yelp 
     for (int i = 0 ; i <= pages ; i++) 
     { 

      document = Jsoup.connect(url).get(); 

      Elements nameElements = document.select(".indexed-biz-name span"); 
      Elements addressElements = document.select(".secondary-attributes address"); 
      Elements phoneElements = document.select(".biz-phone"); 

      for (Element element : nameElements) 
      { 
       names.add(element.text()); 
      } 

      for (Element element : addressElements) 
      { 
       address.add(element.text()); 
      } 

      for (Element element : phoneElements) 
      { 
       phone.add(element.text()); 
      } 

      for (int index = 0 ; index < 10 ; index++) 
      { 
       System.out.println("\nLead " + parseCount); 
       System.out.println("Company Name: " + names.get(parseCount)); 
       System.out.println("Address: " + address.get(parseCount)); 
       System.out.println("Phone Number: " + phone.get(parseCount)); 

       parseCount = parseCount + 1; 
      } 

      number = number + 10; 

     } 
    } 
} 

我需要做什麼來增加運行時間超時？

您可以在此文檔始終使用超時，如：

https://jsoup.org/cookbook/input/load-document-from-url

這樣的：

document = Jsoup.connect(url).timeout(3000).get();
