LLM API Exercise

• For the Friday exercise, you will be working on your portfolio project. You should use the knowledge you have gained this week to fetch data from an API and integrate it into your project. You can choose any API you like, but make sure it is relevant to your project and that you can fetch data from it using Java.
• Make sure to document your code and reflect on the problems you solved and the choices you made in your weekly log. This will help you prepare for the Monday review, where you will present your work and discuss it with your peers and instructor.
