Threaded Jokes

Joke API Exercise

This exercise can be done little by little. Start by getting one joke from one API and then add more APIs. You will have to create DTOs for each API and then a mega DTO that contains all the data.

Create a program to get data from 7 differenct web services (APIs) at the same time.
Get the returned value from the web service and save it in DTOs.
Collect all the DTO data in a mega DTO and print it out in a nice format.

Examples of APIs to use:

icanhazdadjoke (this needs a header Accept: application/json)
chucknorris
kanye.rest
whatdoestrumpthink
jokeapi
geek-jokes
official-joke-api

You might want to use the following code to get the ball rolling:

    String[] urls = new String[]{
        "https://icanhazdadjoke.com/",
        "https://api.chucknorris.io/jokes/random",
        "https://api.kanye.rest",
        "https://api.whatdoestrumpthink.com/api/v1/quotes/random",
        "https://v2.jokeapi.dev/joke/Coding?type=single",
        "https://geek-jokes.sameerkumar.website/api?format=json",
        "https://official-joke-api.appspot.com/random_joke"
    };

First you fetch and convert each joke to a DTO one at a time. Create a timer to mesure the time it takes to fetch all jokes.
Then you fetch all jokes at the same time (by using threads) and measure the time it takes to fetch all jokes. Hopefully this speeds things up. You need to work with the ExecutorService and Future classes.
