I tried, but it still failed!

Jody,
Thanks for you answer. I tried just the same as you've done,
but it still didn't work.
The javac compiler said, 'cannot assign value to final variable myVariable' when I initialised it.
Can you try it again? Thanks a lot!

> The important thing to remember here is that although a variable declared final cant be changed, the key here is that it cant be changed "once it has been initialised". Take the following example:-

>

> public class MyClass {
>     public final String myVariable;
>     public String myMethod() {
>         // here, myVariable can be initialised
>         .
>         .
>         myVariable = "a value";
>         // here, myVariable has been set and cannot be changed.
>     }
> }
