Garbage Collection (GC) is automated in modern programming platforms, but developers should pay close attention to it. Inefficient GC can lead to poor customer experiences, significant financial waste, and missed performance improvements. By optimizing GC, application response times can improve dramatically without code changes, proving its critical role in performance monitoring and capacity planning.
In Java 9, G1 GC will become the default garbage collector. One of the key features of G1 Garbage collector is its ability to limit the GC pause time (i.e. you can set the desired maximum pause time) without compromising on throughput.
Here are few Java Garbage Collection questions that may help in your next interview. What are different regions in JVM memory?
