Learn Java from Scratch - A Beginner's Guide - Step 10 - Building REST API to Delete a Course – DELETE

The video tutorial covers building a delete API using Spring Boot, highlighting the simplicity of using delete mapping and repository methods. It discusses the autoconfiguration features of Spring Boot and JPA, and the use of H2 in-memory database for data initialization. The limitations of H2, such as data loss on server restart, are addressed, and the potential for connecting to real databases like MySQL is introduced.
