[FIXED] How can code use an object inside a button?

Issue

I have an issue. I want to use my object which is outside a button, and I get an error message:

Local variable es defined in an enclosing scope must be final or effectively final

File inputfile = new File("./input.txt");
testobject to = null;
try {
    Scanner inputscan = new Scanner(inputfile);
    String text1 = inputscan.nextLine();
    String text2 = inputscan.nextLine();
    to = new testobject(text1,text2);

    inputscan.close();
} catch (Exception e)  {
    System.err.println(e);
}

JButton btnSave = new JButton("Save");
btnSave.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        to.setSomething("test");
    }
});

Obviously, I have a class with a constructor etc... but I have a problem that I cant reach my object inside the button.

Solution

I tried the first method, maybe I did something worng but it didn't work. The second method is working, but this create a new object in the button, so if I want to use outside a button, I need to set everything again. And in my program it is very complicated etc...

So the solution I created an Arraylist and I can use this inside and outside the button too.

ArrayList<testobject> list = new ArrayList<testobject>();

And after this I set the first (0) element to my data

list.add(new testobject(text1,text2));

And after this I can easily use easily the methods of the class

list.get(0).setSomething("test");
