Quick study sessions to strengthen memory and retain key concepts.
Why do 'Stop-The-World' pauses freeze HTTP requests?
Threads handling requests are paused. Frame the concept in practical terms so you can explain it during interview…
View Card →What makes ZGC ideal for large heap sizes?
Handles large heaps with minimal pause times. ZGC is designed to handle very large heap sizes, making it…
View Card →How does G1GC decide which heap regions to collect?
By prioritizing regions with the most garbage first. G1GC uses a heuristic approach to prioritize regions that contain…
View Card →How would you explain a full GC in a Java interview?
A comprehensive cleaning of the entire heap. A full GC is a garbage collection event that cleans the…
View Card →Why is concurrent memory relocation significant in ZGC?
It reduces pause times to sub-millisecond. ZGC, the Z Garbage Collector, performs concurrent memory relocation, meaning the application…
View Card →How does G1GC minimize Stop-The-World pauses?
By dividing the heap into regions. Frame the concept in practical terms so you can explain it during…
View Card →How would you explain a 'Stop-The-World' pause in a Java interview?
A halt of all application threads during garbage collection. In Java, a 'Stop-The-World' pause occurs when the JVM…
View Card →Why correlate GC logs, heap dumps, and thread dumps?
Because each artifact answers a different runtime question. GC logs explain collector behavior over time, heap dumps explain…
View Card →Understanding Heap Dumps and Memory Leaks?
Heap Dumps capture a snapshot of JVM memory to help identify memory leaks. A Heap Dump provides a…
View Card →What are the trade-offs between G1GC and ZGC?
G1GC offers predictable pause times, while ZGC provides lower latency at increased complexity. G1GC is designed for predictable…
