Unable to find lessons about Interfaces in Java

Greetings Codecademy moderators and members!

I am currently on the ‘CreateREST APIs with Spring and Java’ Skill Path. This week I’ve been looking into two broad lesson modules namely ‘Responding to Requests’ & ‘Spring Context’. The contents of the lessons seem to require a good working understanding of Interfaces, which I do not seem to recall having studied in the previous sections of this particular skill path. I’m unable to locate the ‘Interfaces’ topic anywhere in any of the Java courses. Can someone please point me in the right direction - which course should I refer to gain a deeper understanding about Interfaces in Java

I have the same exact question but on the intermediate java course. There is no lesson (at least from my experience) on interfaces. Can someone at Codecademy please fix this.

I haven’t taken the Intermediate Java course, so I don’t know for sure. But, it does appear that there is a lesson titled “Interfaces” in the “Generics and Collections” module of the course. I don’t know how much detail the lesson goes into.

Also a couple of links from other Codecademy resources:


The lesson teaches you about generic interfaces which depends on previous knowledge on non-generic interfaces, there are no lessons on non-generic interfaces, but that article will surely help. Thank you for your help.
