Old : Where objects that have survived multiple garbage collections are promoted. Humongous : Where very large objects that do not fit into a standard region are allocated. Key Concepts 1. Region-Based Memory Management : Each region is typically between 1 MB and 32 MB. The number of regions and their size can be controlled via the -XX:G1HeapRegionSize parameter. 2. Young and Old Generation : Unlike traditional generational collectors that have contiguous spaces for young and old generations, G1 has regions that can dynamically change their role. Young Ge...
