java代码如何调用第三方接口呢?

Java代码调用第三方接口，可使用以下方法
   HttpURLConnection
     或
   HttpClient来发送HTTP请求到第三方接口的URL

    此方法请求时，可设置头部信息及请求体参数

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

public class CallThirdPartyApi {
    public static void main(String[] args) {
        try {
            URL url = new URL("http://java265.com/api");
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");
            connection.setRequestProperty("Content-Type", "application/json");

            BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String inputLine;
            StringBuffer response = new StringBuffer();

            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
            }
            in.close();

            System.out.println(response.toString());
            connection.disconnect();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
