What triggers object promotion to the Old Generation?

Java: Generational GC
Answer
Surviving multiple Minor GCs. Frame the concept in practical terms so you can explain it during interview discussion.
Objects are promoted from the Young Generation to the Old Generation when they survive several rounds of Minor Garbage Collection. This process assumes that objects which last longer are likely to continue being useful. This strategy helps in efficiently managing memory by segregating short-lived objects from long-lived ones. For instance, a long-term cache might consist of objects that have been promoted after surviving initial garbage collections.
