The variable concerned has block scope within main.
You cannot apply the static modifier here.

static final int increment = 11;

my compiler says no with

Illegal modifier for parameter increment only final is permitted	

So, you *could say*

final int increment

however this is not a constant because it's (potential) value is not 
known at the time of declaration, at this point it is a 'variable'

later you can say (for example)

increment = Integer.parseInt(args[1]);

Now it's a final int but not a constant according to you via apparently 
the JLS and 'normal Java terminology'

You could increase the visibility of increment to class scope, then you 
*can* say

static final int increment = 11;

but you can also say

static final int increment;

increment is not a constant, it's an uninitialized static final int, 
there's a difference.

You can then say

increment = 11;

However this would make the scope of increment wider which is another 
Bloch no no.

Obviously I can't prove the following in Java as the reserved word const 
is unused so I'll use C

in C (gcc -std=c99)

const int x;

x is a constant

If you don't initialize at declaration time it has value 0 and cannot be 
changed, it is in effect read only. If you try and do this later

x = 10;  compiler says no.

Of course you can do this

const int x = 10;

but only at the time of declaration.

So then Arne, how exactly would you make the variable increment constant 
within main using your own criteria of a 'constant' in Java being static 
final.

As always I'll be delighted to be shown how wrong I am.
