Java: Stack vs Heap
Answer
Metaspace stores class metadata. Frame the concept in practical terms so you can explain it during interview discussion.
Metaspace is a memory area in the JVM that stores metadata about the classes used in a Java application. Unlike the old PermGen, Metaspace grows dynamically and is not limited by the JVM heap size, reducing the risk of out-of-memory errors. This is important for applications that load many classes, like plugins or modules in an e-commerce system.
