如何将KeyListener添加到整个项目？

Question

I am developing an app that requires multiple JFrames. The JFrame writes to a file, then is disposed. I want to have a KeyListener listen for the same key press, throughout the entire project without having to create the KeyListener in each class. Is there a way?

我同意应该使用键绑定 ，但是由于我无法删除接受的答案，因此必须将其保留在此处。
