Can primitive data types be placed in the dynamic memory area (Heap)?

In Java, primitive data types (int, boolean, char, etc.) are stored on the stack if they are declared as local variables. However, if primitives are used inside objects, then the objects themselves are placed on the heap, and the primitive fields of the object are also stored on the heap as part of the object.

Additionally, if primitives are wrapped in their corresponding wrapper classes (e.g., Integer, Boolean), then these objects are located on the heap.

Thus, primitive types themselves are not stored on the heap, but their values can be located on the heap as part of objects or wrappers.

Example:

class Example {
    int number; // object field, stored on the heap along with the object
}

public class Main {
    public static void main(String[] args) {
        int localVar = 5; // local variable, stored on the stack
        Example ex = new Example(); // object on the heap, the field number is also on the heap
    }
}
