Wondering how to link a keyboard key to a JButton in netbeans, Downloaded KeyEventDemo program from oracle that lets you press a key and it tells you the keycode, Now im wondering how to implement that, working on a calculator project and I already have the ability to click on any button and have it either + , - , / , * or enter so now I am wondering how to link the 2 together, essentially I'm trying to figure out how to check which key is being pressed in a method, and then run a method depending on what they pressed! 想知道如何将键盘键链接到netbeans中的JButton，从oracle下载的KeyEventDemo程序可以让您按下一个键并告诉您键码，现在我想知道如何实现它，在计算器项目上工作，我已经具备了能力单击任何按钮并使其为+ ， - ， / ， *或输入，所以现在我想知道如何将2链接在一起，本质上我试图弄清楚如何检查方法中按下了哪个键，然后根据他们按下的内容运行一个方法！ thanks for any info! 感谢您提供任何信息！

See How to Use Key Bindings . 请参阅如何使用键绑定。 Basically you bind a KeyStroke to an Action. 基本上，您将KeyStroke绑定到Action。 The tutorial also has a section on How to Use Actions. 本教程还包含有关如何使用动作的部分。
