Daily Hack #day28 - Code Generator

A code generator is a software tool or application that automates the process of generating code snippets, templates, or entire programs based on predefined rules, templates, or user input. It simplifies and speeds up the development process by eliminating repetitive tasks and reducing the need for manual coding.

Code generators can be used for various purposes, such as creating database queries, API endpoints, user interface components, configuration files, and more.

These tools are especially useful in scenarios where developers need to generate boilerplate code or implement standard patterns quickly and consistently. By leveraging code generators, developers can focus more on solving business problems and implementing custom logic, rather than spending time on mundane coding tasks.

One such tool can be found following this link

Just select the language you wish to use, provide a prompt and magic !!

Prompt example:

Create a program that generates random secure passwords, add support to generate multiple passwords at once i.e. 10

Resulting Code snippet:

package com.cloudtuned.demo;

import java.util.Random;

public class PasswordGenerator {
    public static void main(String[] args) {
        int numPasswords = 10;
        int passwordLength = 16;
        generatePasswords(numPasswords, passwordLength);

    public static void generatePasswords(int numPasswords, int passwordLength) {
        String characters = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*()_+";
        Random random = new Random();

        for (int i = 0; i < numPasswords; i++) {
            StringBuilder password = new StringBuilder();
            for (int j = 0; j < passwordLength; j++) {
                int index = random.nextInt(characters.length());

Have ideas for enhancing the PasswordGenerator program? Feel free to copy the code and implement your improvements! Here are a few ideas to get you started:

  1. Error Handling: Implement error handling to handle edge cases, such as invalid patterns or charsets.
  2. Parameterization: Allow users to specify custom patterns and charsets as input parameters to the generatePasswords method.
  3. More Parameterization: Allow users to define how many random passpords the program should generate.
  4. Efficiency: Explore ways to optimize the generation process for larger patterns or charsets.
  5. Unit Tests: Add additional unit tests to ensure the correctness and robustness of the code.
  6. Documentation: Improve code documentation to provide clearer explanations of the program's functionality and usage.
