如何在Java中调用点击链接的方法？

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

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

            // 打开URL连接
            URLConnection connection = url.openConnection();

            // 设置连接属性
            connection.setRequestProperty("User-Agent", "Mozilla/5.0");

            // 发送请求并获取响应
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String line;
            StringBuilder response = new StringBuilder();
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();

            // 处理响应内容
            System.out.println(response.toString());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
