In the JVM, objects are initially created in the Young Generation, which is optimized for quick memory allocation and cleanup. Moving objects from the Young Generation to the Old Generation occurs in the following situations:
- The object has survived several garbage collection cycles in the Young Generation (usually after several Minor GCs).
- The object consumes too much memory or has a long lifespan, making it inefficient to store in the Young Generation.
When an object "survives" multiple garbage collections in the Young Generation, it is considered long-lived and is moved to the Old Generation, where garbage collection occurs less frequently but takes more time.
This helps optimize the garbage collector's performance by segregating objects based on their lifespan and reducing the frequency and volume of cleanup in the Old Generation.
