Java local variable visibility in anonymous inner classes – why is ‘final’ keyword required?

I have this function that creates some buttons. I’m trying to out.println item in the doAction method.

    for (int i = 0; i < itemsList.size(); i++) {
        String item = itemsList.get(i);
        TButton button = new TButton("" + item, 8, 415 + (25 * i), 90, 25) {
            public void doAction() {
                System.out.println("" + item);
            }
        };
        this.framework.add(button);
    }

I’m getting the error

local variable item is accessed from within inner class

How do I do this the right way?

Answer 1

Making item final should solve your problem:

final String item = itemsList.get(i);

You can’t access a non-final local variable from an inner or anonymous class like this.
