Can you list different generations of garbage collectors and explain their features?

Answer from AI
In Java, the Garbage Collector typically divides memory into generations for optimization:
-
Young Generation — where newly created objects are placed. Garbage collection here occurs frequently but quickly, as most objects become unnecessary rapidly.
-
Tenured or Old Generation — objects that have survived several collection cycles in the young generation are moved here. Garbage collection occurs less frequently here but takes more time.
-
Permanent Generation (or Metaspace in newer versions) — stores class metadata and other administrative information.
This division allows for efficient memory management, minimizing pause times during garbage collection and improving application performance.
