Как увеличить счетчик (локальную переменную) при нажатии JButton (Java Swing)? ⇐ JAVA

[Гость]

It doesn't let me saying it should be final or effectively final.

Here's a snippet:

int hrs = 0; JButton plus = new JButton(); plus.addActionListener(e -> hrs++); How do I increase hrs? (I want it to be a local variable in main)
