Understanding Garbage Collection in Java:

When a Java virtual machine (JVM) faces memory allocation challenges due to insufficient space in the heap, it triggers a memory allocation fault leading to the invocation of the Garbage Collector. This essential component's primary role is to reclaim unused memory segments from the heap, thus facilitating efficient memory management in Java applications.

Enhanced Heap Analysis with Verbose GC:

Verbose GC is a command-line option that provides detailed insights into each garbage collection cycle. By enabling this feature, developers can monitor heap usage variations, assess the effectiveness of garbage collection processes, and diagnose potential issues such as excessive collection durations or JVM crashes.

With the IBM Pattern Modeling and Analysis Tool for Java Garbage Collector, developers can leverage advanced analytical capabilities to streamline Java heap management and optimize memory performance.
