Java Memory Leak Explained 🚨 Live Simulation & Java Virtual Machine Monitoring (Step-by-Step Demo)

💥 What really happens when a Java program runs into a memory leak?
In this demo, I’ll simulate one step by step and show you exactly how the JVM’s heap space fills up in real time.

💡 This video covers:
👉 Watch a simple Java class create a memory leak.
👉 See how garbage collection responds as memory usage spikes.
👉 Learn how to monitor JVM memory with JVisualVM and Java Mission Control.
👉 Discover why OutOfMemoryError and GC overhead exceeded errors happen.
👉 Explore heap dumps & thread dumps to analyze leaks like a pro.

Who is this video for?
✔️ Java developers
✔️ Performance engineers
✔️ Anyone curious about JVM internals & memory management
