Need help for Training Data or (Java Tutorial APIs)

Hello everyone! I am a student and my thesis is to build a chatbot solely for Java purposes. The chatbot’s limitation is that it cannot debug a user-inputted code but it should provide a suggestion on a topic related to that. Kind of like W3School’s explanation of every topic about Java with a simple code snippet. I am having a hard time gathering the training data(bot responses) although w3schools, javatpoint, geeksforgeeks and such exist. Do you have any idea where I can get one or a Java tutorial website that has an API available publicly? or should I just get the data manually (web scraping)
