Garbage Collection is used to manage memory by automatically reclaiming memory occupied by objects that are no longer in use, to prevent memory leaks and optimize memory usage.
The flag -XX:+PrintGCDetails enables detailed logging of garbage collection events, which helps in monitoring and tuning the GC performance.
Which Garbage Collector is best suited for applications requiring very low latency in a heavily multi-threaded application?
ZGC (Z Garbage Collector) is designed for applications requiring very low latency, as it aims to keep pause times below 10 milliseconds even for large heaps.
