No problem!

oh yea thanks

bruh

YO I just checked idk why it sounds like that

You're welcome!

the plus makes it so the thing after gets ADDED to the string. so the string starts off with nothing in it and each time it goes through the for loop, one letter from the str string is added to result. (it goes backwards so its reversed.)

just keep coding :) if u dont know what to code go learn something new and maybe some cool ideas will pop into ur head!

Some people want to learn swing. I can teach both so it’s fine. If I make a JavaFX video I’ll put it in the title.

Wow, thank you!

It means your openAI account doesn’t have any funds/money left

-1 means the index of last character, because index starts from zero, so when you want to get last characters' index you should add this -1

array {1, 2, 3, 4, 5} There's 5 elements inside, it has a length of 5. However, if we want to know the index of each element inside the array the value '1' is at position '0' which means element '5' is at position '4', so to get the value '5' we need to write array[4]. given N is the length of the array, n-1 determins the position of those elements. If simple wrote i = str.length; you would get an out of bounds exception element because the element '5' is at position '4', not position '5'. Following the formular n-1, we say str.-length-1 to ensure we always end up at the last element contained within the array.

Thank you for your valuable information

@@HorridOnlineTroll You're amazing!

Yeah you have to pay but its really cheap

If it's java, it's going to work. If it doesn't you most likely forgot to import something.

Glad to help!

Check your api key is working and valid. Make sure it is not expired if it is a free trial.

No problem!

send ur code here

Check your api key is valid not expired and works. Also check how much free trial money you have left if you are in the free trial. (Other people have had the same issue before)

Can you provide some info? Like give me your code so I can see whats wrong. Also maybe tell me your version of Java? New Java versions come out all the time and can break old code. discord help server: discord.gg/hhGu6mV5wm <-----

Your way works and is more simple than my way, however this video is supposed to teach those who don’t know how to reverse a sting WITHOUT StringBuilder. (For example in a AP CSA class they would ask you to do this without StringBuilder)

interviews tend to not allow things like StringBuilder, while yes it is more efficient, they want to see if you know the fundamental logic

You're welcome! There’s no reason learning something like this should take super long.

Happy to help

what

@@mintype Thank you, it worked kzfaq.infoFB6--ys9yGM?feature=shared

On what

on this topic ofc@@mintype

You have a ; (semicolon) at the end of your for loop!!!! updated code: String input ="Hello world!"; String output=" "; for(int i=input.length()-1;i>=0;i--) output+=input.charAt(i); System.out.println(output);

@@mintype Thank you so much!

Thank you

Thank you

Thank you

Prompt the API with "continue" after if it is incomplete.

Its the pinned comment.

Glad it was helpful!

Error 429 may happen to you if you send too many requests in a short period of time.

@@mintype with a new user and new key if i do the first request the code is it. Is possible any change with free counter politic?

@@mintype Bro even showing 429 for first time call 🤔

​@@mintypein first request this happens

Does anyone solve this problem? I'm having the same issue. I'm using Eclipse IDE

Heres the code (updated): import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.io.OutputStreamWriter; import java.net.HttpURLConnection; import java.net.URL; public class Main { public static void main(String[] args) { System.out.println(chatGPT("hello, how are you?")); // Prints out a response to the question. } public static String chatGPT(String message) { String url = "api.openai.com/v1/chat/completions"; String apiKey = "KEY GOES HERE!!!!!!!!!!!"; // API key goes here String model = "gpt-3.5-turbo"; // current model of chatgpt api try { // Create the HTTP POST request URL obj = new URL(url); HttpURLConnection con = (HttpURLConnection) obj.openConnection(); con.setRequestMethod("POST"); con.setRequestProperty("Authorization", "Bearer " + apiKey); con.setRequestProperty("Content-Type", "application/json"); // Build the request body String body = "{\"model\": \"" + model + "\", \"messages\": [{\"role\": \"user\", \"content\": \"" + message + "\"}]}"; con.setDoOutput(true); OutputStreamWriter writer = new OutputStreamWriter(con.getOutputStream()); writer.write(body); writer.flush(); writer.close(); // Get the response BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream())); String inputLine; StringBuffer response = new StringBuffer(); while ((inputLine = in.readLine()) != null) { response.append(inputLine); } in.close(); // returns the extracted contents of the response. return extractContentFromResponse(response.toString()); } catch (IOException e) { throw new RuntimeException(e); } } // This method extracts the response expected from chatgpt and returns it. public static String extractContentFromResponse(String response) { int startMarker = response.indexOf("content")+11; // Marker for where the content starts. int endMarker = response.indexOf("\"", startMarker); // Marker for where the content ends. return response.substring(startMarker, endMarker); // Returns the substring containing only the response. } }

@@mintype hello

Check if your API free trial has expired yet. Many people get the same issue and don't realize their trial has expired.

One way to do this is to create a GUI with Java Swing or JavaFX. I have a video on swing. Then you can use keyListener to listen for the R key and turn it on or off. However, please take note that the GUI has to be open when you press R on your keyboard. Java doesn't have any way of doing this without the GUI focused. (There are GitHub repositories which might help, but I'm not certain they work!)

You're welcome!

Good to hear

Hey is it free?
