Since I gave up on Java after being subjected to it as the “you’ll never use this, so its great to teach patterns” language, I trust a well-instructed GPT-4 AI to give you a head-start in making a request. There’s also community-produced libraries.
I’ve analyzed the code you provided, and I can see that there are a few issues that need to be addressed to make it work correctly with the OpenAI API. Here’s a summary of the issues:
- The code is written in a mix of Java and Python syntax, which will cause compilation errors.
- The
OPENAI_API_ENDPOINT and OPENAI_API_KEY variables are not defined.
- The request body is not formatted correctly as JSON, and the required headers are not set.
To fix these issues, I’ve written a complete Java example that demonstrates how to use the OpenAI API to request and receive an AI-generated image from DALL-E. This example uses the OkHttp library for making HTTP requests and the Gson library for handling JSON. Make sure to add these dependencies to your project:
<!-- Add this to your pom.xml -->
<dependencies>
<dependency>
<groupId>com.squareup.okhttp3</groupId>
<artifactId>okhttp</artifactId>
<version>4.9.3</version>
</dependency>
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.8.9</version>
</dependency>
</dependencies>
Here’s the updated Java code:
import com.google.gson.Gson;
import com.google.gson.JsonObject;
import okhttp3.*;
import java.io.IOException;
public class OpenAIDemo {
private static final String OPENAI_API_ENDPOINT = "https://api.openai.com/v1/images/generations";
private static final String OPENAI_API_KEY = "your_openai_api_key_here";
public static void main(String[] args) {
String prompt = "generate a little robot";
String imageUrl = callOpenAIAndReturnImage(prompt);
System.out.println("Image URL: " + imageUrl);
}
private static String callOpenAIAndReturnImage(String prompt) {
OkHttpClient client = new OkHttpClient();
Gson gson = new Gson();
JsonObject requestBodyJson = new JsonObject();
requestBodyJson.addProperty("model", "dall-e-3");
requestBodyJson.addProperty("prompt", prompt);
requestBodyJson.addProperty("size", "1024x1024");
RequestBody requestBody = RequestBody.create(requestBodyJson.toString(), MediaType.parse("application/json"));
Request request = new Request.Builder()
.url(OPENAI_API_ENDPOINT)
.header("Content-Type", "application/json")
.header("Authorization", "Bearer " + OPENAI_API_KEY)
.post(requestBody)
.build();
try {
Response response = client.newCall(request).execute();
if (response.isSuccessful()) {
String responseBody = response.body().string();
JsonObject responseJson = gson.fromJson(responseBody, JsonObject.class);
return responseJson.getAsJsonArray("data").get(0).getAsJsonObject().get("url").getAsString();
} else {
System.out.println("OpenAI API request failed with response: " + response.body().string());
}
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}
Replace your_openai_api_key_here with your actual OpenAI API key. This code should now work correctly to interact with the OpenAI API and receive an AI-generated image from DALL-E.

I will now analyze the provided Java code section-by-section, explaining how it operates and how the HTTPS request is formed. I will also verify if each step appears to work correctly or has any faults in operation.
- Import statements:
import com.google.gson.Gson;
import com.google.gson.JsonObject;
import okhttp3.*;
import java.io.IOException;
These import statements are correct and necessary for the code to function. They import the required classes from the OkHttp and Gson libraries, as well as the IOException class from the Java standard library.
- Constants definition:
private static final String OPENAI_API_ENDPOINT = "https://api.openai.com/v1/images/generations";
private static final String OPENAI_API_KEY = "your_openai_api_key_here";
These constants define the API endpoint and the API key. The endpoint is correct, and the API key should be replaced with the actual OpenAI API key. This part of the code is correct.
- Main method:
public static void main(String[] args) {
String prompt = "generate a little robot";
String imageUrl = callOpenAIAndReturnImage(prompt);
System.out.println("Image URL: " + imageUrl);
}
The main method sets the prompt, calls the callOpenAIAndReturnImage method with the prompt, and prints the returned image URL. This part of the code is correct.
- callOpenAIAndReturnImage method:
private static String callOpenAIAndReturnImage(String prompt) {
OkHttpClient client = new OkHttpClient();
Gson gson = new Gson();
JsonObject requestBodyJson = new JsonObject();
requestBodyJson.addProperty("model", "dall-e-3");
requestBodyJson.addProperty("prompt", prompt);
requestBodyJson.addProperty("size", "1024x1024");
RequestBody requestBody = RequestBody.create(requestBodyJson.toString(), MediaType.parse("application/json"));
Request request = new Request.Builder()
.url(OPENAI_API_ENDPOINT)
.header("Content-Type", "application/json")
.header("Authorization", "Bearer " + OPENAI_API_KEY)
.post(requestBody)
.build();
This part of the code initializes the OkHttpClient and Gson instances, creates a JSON object for the request body, and sets the required properties (model, prompt, and size). It then creates a RequestBody instance with the JSON object and MediaType, and builds the Request object with the API endpoint, headers, and request body. This part of the code is correct.
- Sending the request and handling the response:
try {
Response response = client.newCall(request).execute();
if (response.isSuccessful()) {
String responseBody = response.body().string();
JsonObject responseJson = gson.fromJson(responseBody, JsonObject.class);
return responseJson.getAsJsonArray("data").get(0).getAsJsonObject().get("url").getAsString();
} else {
System.out.println("OpenAI API request failed with response: " + response.body().string());
}
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
This part of the code sends the request using the OkHttpClient instance and handles the response. If the response is successful, it extracts the image URL from the JSON response and returns it. If the response is not successful, it prints an error message. If an IOException occurs, it prints the stack trace. This part of the code is correct.
In conclusion, the provided Java code appears to be correct and should work as expected. It sends the same type of POST request as the cURL example and extracts the image URL from the response object. There are no compilation errors or malfunctions in the code.
The AI may not know changes in default libraries that have happened in the last 2-3 years.
