In this short and concise course you will learn everything to get started with web scraping using Java. You will learn the concepts behind web scraping that you can apply to practically any web page (static AND dynamic / AJAX). Course structure We start with an overview of what web scraping is and what you can do with it. Then we explain the difference in scraping static pages vs dynamic / AJAX pages. You learn how to classify a website in one of the two categories and then apply the right concept in order to scrape the data you want. Now you will learn how to export the scraped data either as CSV or JSON. These are some popular formats that can be used for further processing. Unfortunately many websites try to block scrapers or sometimes you just do not want to be detected. In the section going undercover you will learn how to stay undetected and avoid getting blocked. At the end of the course you can download the full source code of all the lectures and we discuss an outlook to some advanced topics (private proxies, cloud deployment, multi threading...). Those advanced topics are covered in a follow up course I am going to teach.
