Java: How to connect to an API using Java

In this video, I showcase how we can connect to an API and get some JSON data from any API. I am using the metaweather API. You can find more information about the API at:
THE WEATHER API IS NOT ONLINE AT THIS MOMENT

Video about some other free APIs

I made a JavaFX gui login page and need the information being passed through it for the username and password can you do a video on how that works and it returns success and the token

Thank you for the vedio, just one question the import org.json.simple.JSONObject; and import doesn't work on my netbeans should i download a library of json.

Hi, I get a java.lang.ClassCastException Exception every time I run the code. Does anyone know how to solve this?


Full error:
java.lang.ClassCastException: class org.json.simple.JSONObject cannot be cast to class org.json.simple.JSONArray (org.json.simple.JSONObject and org.json.simple.JSONArray are in unnamed module of loader 'app')
at main.main(main.java:38)

Code:
JSONParser parse = new JSONParser();
JSONArray dataObject = (JSONArray)

Spring introduced HTTP Interfaces. Less boilerplate code.

I can't import JsonParser, but Jsonobject and JsonArray work

thanks for this vid! however, after getting this data, how do you display it to your JSP or how is it implemented in a model to display in jsp etc..

I use axios and makes it all easier so this java edition is quite hard to grasp honestly.

1:15 Hello I simply cannot understand what are you saying there exactly could you tell me how and which maven did you add and how did you add the dependancy ? Much apriciated

[blackwalker]

Good morning, hope you're going well. Please I have to create a simple web service and I want to connect my java code to API tool. But my java project is "Dynamic Web Projet". How can I do that for import a JSON library to make my code works?

[crazymnd]

thx, for noob like me - you also need to download correct JAR file and add it to depencies

[kangnifredable]

Excuse me but it is not too clear how you call the Java api in your react code

[leonard-riccardowecke]

Question: this is a https url but it is a Http request. Is the information I will send in the body encrypted? I want to authenticate with a client key and secret for an api via oauth1.

[Cengokill]

You didn't explain how to create this kind of project with pom.xml. What is that ?

[ikelloydyana]

Do you know how to use IMAGE MODERATION API in java?

[shahabshafiee]

stop scrolling 😅. you gave me a headache.

[FrissOderLassEs]

Maybe, next time, jump a bit more forth and back in the code, mark more stuff and do all of it even faster, if possible
