Can I use the lambda everytime I would pass an object that implements an interface?
Like the example below:

JButton button = new JButton();

// Without Lambda
button.addActionListener(new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent e) {
        System.out.println("Doing something.");
    }
});

// With Lambda
button.addActionListener(e -> {
    System.out.println("Doing something.");
});
