Hi Miki,

I see no problems there. You can definately declare an array as final and static both.

If you are having a problem somewhere in a program, I guess it might be because you are either declaring the array inside a static context, or may be you are trying to change the reference of this array .

I am writing a code here :


This will give you a compilation error because you are trying to change the reference value of the array that has been declared as "final". This is illegal.

however, in the following code :




there is no problem here. This code compiles and prints the output :



so, the moral of the story is : "when you declare an array as final, you can change the elements in the array, however you cannot change the reference of this array."

Hope it helps you

All the best
