Where in JVM memory is information about primitive data types stored?

In the JVM, primitive data types (int, byte, short, long, float, double, char, boolean) are stored directly in the stack or in the memory area allocated for local variables and object fields, depending on the context.

• Local primitives (e.g., variables inside methods) are stored in the call stack.
• Primitive fields of objects are stored in the heap inside the object.

Information about the types themselves (e.g., class metadata, type descriptions) is stored in a memory area called the method area, which contains data about classes and their structure.

Thus, primitive values are stored directly in memory (stack or heap), and type descriptions are in the JVM's method area.
