Question

In java, if a method has a final variable (not static), and If I am calling the method multiple times, can the final variable have different values in each call?

public void method1(String msg){
        final ArrayList<MessageObject> list =  method2(msg);
        // code that uses list (example just prints) 
}

method1("one")
method1("two") are two calls, 

if method2() returns different lists for each input, is the above code valid (with respect to final modifier?)

Answer 1

Yes, absolutely. final only means that that particular variable can’t be assigned a different value.

If you have multiple calls to the method (whether via recursion or multiple threads) those are entirely separate variables.
