Where are static methods and static variables stored in Java?
When we create a static variable or method it is stored in a special area on the heap: PermGen(Permanent Generation), where it lays down all the data applying to classes(non-instance data). Starting from Java 8 the PermGen became - Metaspace.
Understanding storage of static methods and static variables in Java
Jul 26, 2024 · In Java 5 and 6, static methods and variables were stored in PermGen. However, Java 8 introduced significant changes to the memory model, replacing PermGen with MetaSpace. MetaSpace stores class metadata, including names, fields, methods, bytecodes, constant pools, and JIT optimizations.
Where are static variables stored in java? - Stack Overflow
Jun 28, 2015 · In the JVM memory model the reference to and value of static variables are both stored in the method area which itself is in the heap. The method area is created on virtual machine start-up. Although the method area is logically part of the heap, simple implementations may choose not to either garbage collect or compact it.
What is the actual memory place for static variables?
Feb 26, 2021 · The static variables are provided the memory in the the same memory segment where the code is stored i.e. Class Area. It is independent of the stack or heap segment of memory. It remains accessible during the complete duration of the program.
