怎么写一个java程序来引用chatgpt openai 具体的代码是什么

要使用ChatGPT OpenAI，需要安装OpenAI API并获取API密钥。以下是一个示例程序，可以引用ChatGPT OpenAI，进行简单的聊天：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.HashMap;
import java.util.Map;

import okhttp3.MediaType;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;

import org.json.JSONObject;

public class ChatGPT {

    private static final MediaType JSON = MediaType.parse("application/json; charset=utf-8");
    private static final String API_KEY = "YOUR_API_KEY";
    private static final String MODEL_ID = "YOUR_MODEL_ID";
    private static final String API_URL = "https://api.openai.com/v1/engine/" + MODEL_ID + "/completions";
    private static OkHttpClient client = new OkHttpClient();

    public static void main(String[] args) throws Exception {
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        while (true) {
            System.out.print("You: ");
            String prompt = reader.readLine();
            String response = getChatResponse(prompt);
            System.out.println("ChatGPT: " + response);
        }
    }

    public static String getChatResponse(String prompt) throws IOException {
        Map<String, Object> jsonMap = new HashMap<>();
        jsonMap.put("prompt", prompt);
        jsonMap.put("temperature", 0.5);
        jsonMap.put("max_tokens", 50);

        JSONObject jsonObject = new JSONObject(jsonMap);
        RequestBody body = RequestBody.create(jsonObject.toString(), JSON);
        Request request = new Request.Builder()
                .header("Content-Type", "application/json")
                .header("Authorization", "Bearer " + API_KEY)
                .url(API_URL)
                .post(body)
                .build();

        try (Response response = client.newCall(request).execute()) {
            String responseBody = response.body().string();
            JSONObject jsonResponse = new JSONObject(responseBody);
            String text = jsonResponse.getJSONArray("choices").getJSONObject(0).getString("text");
            return text;
        }
    }
}

注意，需要将YOUR_API_KEY和YOUR_MODEL_ID替换为您自己的OpenAI API密钥和ChatGPT模型ID。此程序接受用户的输入，并将其发送到OpenAI API以获取ChatGPT的响应。响应将作为字符串返回，并显示在控制台中
