Introduction

ChatGPT is an AI-based chatbot developed by OpenAI. It is built on top of the organization’s GPT⑶.5 and GPT⑷ large language models. This blog post will guide you on how to write Java code to connect to OpenAI’s REST API and demonstrate how to add more functionality to your code.

Creating Your OpenAI Account

Before you can start writing Java code to connect to OpenAI’s REST API, you need to create an account on OpenAI’s platform. Go to https://platform.openai.com and create an account. Once you have an account, navigate to Menu => Personal and select “View API keys.” Create and save your API key for later use. Next, go to the left-side Menu, select Organization => Settings, and request the generation of an “Organization ID.” Copy this ID for later usage.

Java Code

To connect to OpenAI’s REST API, you’ll need to create three Java files: `FileHelper.java`, `Request.json`, and `ChatGPTAPIExample.java`.

FileHelper.java

“`java
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.nio.charset.StandardCharsets;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.LinkedList;
import java.util.List;

public class FileHelper {
public static String readLinesAsString(File file) {
List returnLines = new LinkedList();
String text = “”;
try {
text = new String(Files.readAllBytes(Paths.get(file.getAbsolutePath())), StandardCharsets.UTF_8);
} catch (IOException e) {
e.printStackTrace();
}
return text;
}

public static List readLines(File file) {
List returnLines = new LinkedList();
try {
String text = new String(Files.readAllBytes(Paths.get(file.getAbsolutePath())), StandardCharsets.UTF_8);
String[] lines = text.split(“ ”);
for (String line : lines) {
returnLines.add(line);
}
} catch (IOException e) {
e.printStackTrace();
}
return returnLines;
}

public static void writeStringToFile(String line, File file) {
try {
FileWriter myWriter = null;
if (file.exists()) {
myWriter = new FileWriter(file, true);
} else {
System.out.println(“Could not find the file ” + file + “. Creating it again”);
file.createNewFile();
myWriter = new FileWriter(file);
}
myWriter.write(line);
myWriter.close();
} catch (IOException e) {
e.printStackTrace();
System.out.println(“An error occurred in writing to file ” + file + ” e=” + e);
}
}
}
“`

Request.json

“`
{
“model”: “text-davinci-003”,
“prompt”: “Which was the best selling car 2023 in USA?”,
“max_tokens”: 64,
“temperature”: 0.5
}
“`

ChatGPTAPIExample.java

“`java
import java.io.BufferedReader;
import java.io.File;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.nio.charset.StandardCharsets;

public class ChatGPTAPIExample {
public static void listTokens() {
try {
URL url = new URL(“https://api.openai.com/v1/models”);
HttpURLConnection con = (HttpURLConnection) url.openConnection();
con.setRequestMethod(“GET”);
con.setRequestProperty(“Content-Type”, “application/json”);
con.setRequestProperty(“Accept”, “application/json”);
con.setRequestProperty(“OpenAI-Organization”, “your-org-key”);
con.setDoOutput(true);
con.setRequestProperty(“Authorization”, “Bearer your-api-key”);

int responseCode = con.getResponseCode();
System.out.println(“Response Code : ” + responseCode);

BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();

System.out.println(response);
} catch (Exception e) {
System.out.println(e.getMessage());
}
}

public static void prompts() {
try {
URL url = new URL(“https://api.openai.com/v1/completions”);
HttpURLConnection con = (HttpURLConnection) url.openConnection();
con.setRequestMethod(“POST”);
con.setRequestProperty(“Content-Type”, “application/json”);
con.setRequestProperty(“Accept”, “application/json”);
con.setRequestProperty(“OpenAI-Organization”, “your-org-key”);
con.setDoOutput(true);
con.setRequestProperty(“Authorization”, “Bearer your-api-key”);

String jsonInputString = FileHelper.readLinesAsString(new File(“C:\yourpath\request.json”));
try (OutputStream os = con.getOutputStream()) {
byte[] input = jsonInputString.getBytes(StandardCharsets.UTF_8);
os.write(input, 0, input.length);
}

int responseCode = con.getResponseCode();
System.out.println(“Response Code : ” + responseCode);

BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();

System.out.println(response);
} catch (Exception e) {
System.out.println(e.getMessage());
}
}

public static void main(String[] args) {
listTokens();
prompts();
}
}

Compiling and Running the Code

Once you have the files created, you can compile and run them. You can use your preferred method of building and running Java code. For example, you can use the command line:

“`
javac *.java
java ChatGPTAPIExample
“`

Sample Output

The code will output the response from the API request. For example:

“`
Response Code: 200
{
“id”: “cmpl⑹wFzNtira0jiFrmXHOUkjZpqytNca”,
“object”: “text_completion”,
“created”: 1679342505,
“model”: “text-davinci-003”,
“choices”: [{
“text”: “It is too early to tell which car will be the best-selling car in 2023 in the USA.”,
“index”: 0,
“logprobs”: null,
“finish_reason”: “stop”
}],
“usage”: {
“prompt_tokens”: 10,
“completion_tokens”: 22,
“total_tokens”: 32
}
}
“`

Conclusion

In this blog post, you have learned how to connect your Java application to OpenAI’s API using the provided Java code. You can now integrate OpenAI’s ChatGPT capabilities into your own applications and explore its full potential.
