What is perm space?

Question

While learning about java memory profiling, I keep seeing the term \"perm space\" in addition to \"heap.\" I know what the heap is - what\'s perm space?

Answer 1

• JVM has an internal representation of Java objects and those internal representations are stored in the heap (in the young generation or the tenured generation).
• JVM also has an internal representation of the Java classes and those are stored in the permanent generation
