I asking for ChatGPT to create Random Password Generator extension for AI2, Mit App Inventor, Kodular type of similar site and the result is insane.

The features

  • Customizable password Length
  • Special character
  • Capital Latter
  • Number

Source code

public class PasswordGenerator extends AndroidNonvisibleComponent {

    //Activity and Context
    private Context context;
    private Activity activity;

    public PasswordGenerator(ComponentContainer container){
        this.activity = container.$context();
        this.context = container.$context();

    @SimpleFunction(description = "Generates a random password with customizable options")
    public String GeneratePassword(int passwordLength, int numSpecialChars, int numCapitalLetters, int numNumbers) {

        // Initialize character sets
        String specialChars = "!@#$%^&*()_+-=[]{}|;':\",./<>?";
        String capitalLetters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
        String smallLetters = "abcdefghijklmnopqrstuvwxyz";
        String numbers = "0123456789";

        // Create a string builder to construct the password
        StringBuilder password = new StringBuilder();

        // Set up a random generator
        Random random = new Random();

        // Generate the password with the specified criteria
        for (int i = 0; i < passwordLength; i++) {
            // Decide which character set to choose from randomly
            int charSetIndex = random.nextInt(4);

            // Determine which set to use
            String charSet = "";
            switch (charSetIndex) {
                case 0:
                    charSet = specialChars;
                case 1:
                    charSet = capitalLetters;
                case 2:
                    charSet = smallLetters;
                case 3:
                    charSet = numbers;

            // Generate a random character from the chosen set
            int charIndex = random.nextInt(charSet.length());
            char randomChar = charSet.charAt(charIndex);

            // Add the character to the password builder

            // Count the number of special characters, capital letters, and numbers in the password
            int specialCharCount = 0;
            int capitalLetterCount = 0;
            int numberCount = 0;

            for (int j = 0; j < password.length(); j++) {
                char c = password.charAt(j);
                if (specialChars.indexOf(c) != -1) {
                } else if (capitalLetters.indexOf(c) != -1) {
                } else if (numbers.indexOf(c) != -1) {

            // Check if the criteria for special characters, capital letters, and numbers has been met
            if (specialCharCount == numSpecialChars && capitalLetterCount == numCapitalLetters && numberCount == numNumbers) {

        // Return the generated password
        return password.toString();

Note: I think there was something mistake with the code I hope a expert extension developer spot the mistake and fix it. By the way the extension still usable.

You need to change the package name according to the ChatGPT package name also you need to edit the file name, I am sorry I am not a extension developer I just create for test and educational propose, For more you need to learn you can contact the extension developer

You don’t need to do anything.
Here is an example:

When the button is clicked to generate password, the password in generated and shown in a label.
Nothing more else is needed to do.
