For Sling API in AEM

• https://experienceleague.adobe.com/docs/experience-manager-65/developing/platform/sling-adapters.htm... 

For JCR API in AEM

• https://experienceleague.adobe.com/docs/experience-manager-65/developing/platform/access-jcr.html?la... 

For QueryBuilder API in AEM

• https://experienceleague.adobe.com/docs/experience-manager-64/developing/platform/query-builder/quer... 

For TagMaganer API in AEM

• https://experienceleague.adobe.com/docs/experience-manager-65/developing/platform/tagging/building.h... 

That should cover the somewhat most important parts, but you will need to check the general AEM Java documentation of the classes you are using. It can help to take a look at the WKND project samples to get you started. You will also need to lookup the documentation of the packages specific to your implementation, e.g. if you use GSON, check Google GSON documentation etc.

Hi Brian,

Thanks for the info. I signed up at Pluralsight and have learned a lot from them. In one of your articles you mention, "must have a firm grasp of the fundamentals of the Java language, including data structures, algorithms, and design patterns, as AEM is built on top of Java." Do you have any suggestions where to go for that training? Thanks.

https://www.udemy.com/course/java-the-complete-java-developer-course, I followed this course when I was new to Java. It worked out really well
