Java正则表达式查找与以 /结尾的文件夹的链接

Question

我正在尝试找到以'/'例如'/'的文件夹的链接。www.w3.org/tr/owl-features/使用Java正则表达式，但我无法做到。任何Helpp都将不胜感激这是我的代码

File file4 = new File("W3C Web Pages");
        File[] listOfFiles4 = file4.listFiles();
        for (int i = 0; i < listOfFiles4.length; i++)
        {
          if (listOfFiles4[i].isFile())
          {
            FileReader filereader = new FileReader("W3C Web Pages/"+listOfFiles4[i].getName());    
            BufferedReader br = new BufferedReader(filereader);   
            Pattern regx = Pattern.compile("(https?|ftp|file)://[-a-zA-Z0-9+&@#/%?=~_|!:,.;]*[-a-zA-Z0-9+&@#/%=~_|]");
            String text;
              while ((text = br.readLine()) != null)
              {
                  Matcher linkswslash = regx.matcher(text);
                  if (linkswslash.find())
                  {
                      if(linkswslash.group().contains("/"))
                      {   
                          System.out.println("Found value: " + linkswslash.group());
                      }
                  }
              }
          }
        }

为什么不将您的正则态度更改为"/"，而其他URL则无法匹配，而不匹配"/"。这样的东西：

package com.example;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class Regex1 {
    public static void main(String[] args) {
        System.out.println("in here");
        String text = "https://www.w3.org/TR/owl-features/";
        // wont' match https://www.w3.org/TR/owl-features
        // but will match https://www.w3.org/TR/owl-features/
        Pattern regx = Pattern.compile("(https?|ftp|file)://.*\/$");
        Matcher linkswslash = regx.matcher(text);
        if (linkswslash.find()){
            System.out.println("Found value: " + linkswslash.group());
        } else {
            System.out.println("Not found");
        }
    }
}
