Sample answer is:
I read many blogs regularly to keep myself updated with the latest changes in technology. Some of my favorite blogs are Javaworld.com, baeldung.com, spring.io and Hacker news on ycombinator.com
I also subscribe to some of the mailing lists on important frameworks for open source projects. These help me in increasing my knowledge.
Also from time to time, I read books on the latest technology like Docker, AWS etc to learn new things.
