What is the difference between call by value and call by reference in ...
In Java, when a method is called with call by value, a copy of the variable's value is passed to the method. Any modifications made to the parameter within the method do not affect the original variable. Call by reference, on the other hand, passes the actual variable itself, allowing modifications to affect the original variable.
