I don't understand the difference between by value and by reference...😕😕?

Answer 1

The way I see it...
Pass by Value gives you a snapshot of the variable to use in your method. You can do whatever you want with the snapshot without changing the original variable you passed through with.

Pass by Reference gives you direct manipulation to the variable stored in memory. Pass a variable to the method , modify variable with the method. variable is the new value upon return to the main method
