如何在java脚本中将返回值放入URL

import java.io.*;
import java.net.*;

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

            // 打开与URL之间的连接
            URLConnection connection = url.openConnection();

            // 启用输出流
            connection.setDoOutput(true);

            // 获取输出流
            OutputStream outputStream = connection.getOutputStream();

            // 返回值
            String returnValue = "Hello World";

            // 编码返回值
            String encodedValue = URLEncoder.encode(returnValue, "UTF-8");

            // 将返回值写入输出流
            outputStream.write(encodedValue.getBytes());

            // 关闭输出流
            outputStream.close();

            // 获取输入流
            InputStream inputStream = connection.getInputStream();

            // 读取URL的响应
            BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
            String line;
            StringBuilder response = new StringBuilder();
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }

            // 关闭输入流
            reader.close();

            // 打印URL的响应
            System.out.println(response.toString());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
