在几行java代码中读取url to string

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;

public class ReadURLToString {
    public static void main(String[] args) {
        try {
            // 创建URL对象
            URL url = new URL("https://www.example.com");

            // 打开URL连接
            BufferedReader reader = new BufferedReader(new InputStreamReader(url.openStream()));

            // 读取URL内容并存储到字符串中
            StringBuilder stringBuilder = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                stringBuilder.append(line);
            }
            String urlContent = stringBuilder.toString();

            // 关闭连接
            reader.close();

            // 输出URL内容
            System.out.println(urlContent);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
