Have you ever felt your Java application slowing down for no apparent reason? Often, the problem lies in how memory is managed! The Garbage Collector (GC) is essential for Java performance, but choosing and configuring the right GC can make all the difference in your application's performance.
In this video, I'll show you how Java's different Garbage Collectors (G1, ZGC, Shenandoah, and Parallel GC) work, their advantages, and when to choose each one. We'll also understand heap and stack memory, two fundamental areas where objects and variables are stored. Heap memory is where dynamic objects are allocated and managed by the Garbage Collector, while stack memory is used to store local variables and execution control. Understanding these differences is crucial to optimizing your application and avoiding performance issues.
