Garbage Collection (GC) is a cornerstone of Java's memory management, ensuring efficient use of resources by reclaiming unused objects. But how do we monitor and optimize this critical process in real-time? Enter ๐๐ฎ๐๐ฎ ๐ฉ๐ถ๐๐๐ฎ๐น๐ฉ๐ , a powerful tool that gives developers unparalleled insights into GC performance and memory utilization.

VisualVM provides a visual interface to monitor JVM activity, making it easier to analyze garbage collection patterns, detect memory leaks, and optimize heap usage. With features like heap dumps, thread monitoring, and real-time GC visualization, it transforms complex profiling tasks into actionable insights.
