Learn Java from Scratch - A Beginner's Guide - Step 02 - Comparing Lazy Initialization Versus Eager Initialization

The video tutorial explains the differences between lazy and eager initialization in Spring. Lazy initialization occurs when a bean is first used, while eager initialization happens at application startup. Eager initialization is the default setting. The tutorial covers how to implement both types using annotations, discusses error handling, and compares memory consumption. It concludes with recommendations on when to use each type, suggesting eager initialization for most cases and lazy initialization for rarely used beans.
