Can I know the exact difference between them and when should we use them ....
Thanks in advance.....
In Java, all argument values are passed to a method using only call by value (pass by value) mechanism.
There is no call by reference (pass by reference) mechanism in Java.
“Call by value” in Java means that argument’s value is copied and is passed to the parameter list of a method.
That is, when we call a method with passing argument values to the parameter list, these argument values are copied into the small portion of memory and a copy of each value is passed to the parameters of the called method.
