Guten Tag,
mein Name ist Dennis und ich habe ein Problem! Ich will aus einer anderen klasse auf eine im ActionListener liegende variable zugreifen. Ich bin noch recht neu und weiß nicht wie das geht. Ich würde gerne aus der Eingabe klasse auf den ActionListener aus der Buttons klasse zugreifen und den neuen result wert als Eingabe nutzen und ausgeben!
