what happens a primitive data type is passed in a method call and non-primitive data types are passes? when would there be change in value after downstream operation and opposite

Question

Accepted Answer

Primitive data types are passed by value, while non-primitive data types are passed by reference. Changes in value can occur after downstream operations for non-primitive data types.

Primitive data types (int, float, char, etc.) are passed by value, meaning a copy of the value is passed to the method. Changes made to the parameter inside the method do not affect the original value.
Non-primitive data types (objects, arrays, etc.) are passed by reference, meaning the memory address of the variable is passed to the method. Changes made to the parameter inside the method will affect the original value.
Changes in value can occur after downstream operations for non-primitive data types, as the original object is modified directly.
Example: Passing an array to a method and modifying its elements will result in a change in the original array's values.
