More FAQs in Pass by Value vs Pass by Reference Explained
Pass by Value means a copy of the variable's data is passed to the function. Modifications inside the function do not affect the original variable.
Pass by Reference means the memory address of the variable is passed. Modifications inside the function will alter the original variable's data.
Because integers are primitives. Java passes a copy of the primitive value, so the original variable remains untouched.
