I want to execute a certain function when a user presses a key. This will be run in the console, and the code is in Java. How do I do this? I have almost zero knowledge of key presses/keydowns, so I could really use an explanation as well.

The Windows on-screen keyboard is a program included in Windows that shows an on-screen keyboard to test modifier keys and other special keys. For example, when pressing the Alt , Ctrl , or Shift key, the On-Screen Keyboard highlights the keys as pressed.
ReadKey() Method makes the program wait for a key press and it prevents the screen until a key is pressed. In short, it obtains the next character or any key pressed by the user. The pressed key is displayed in the console window(if any input process will happen).
ReadKey() Obtains the next character or function key pressed by the user. The pressed key is displayed in the console window.

You can't detect an event in the command line environment. You should provide a GUI, and then you can use the KeyListener class to detect a keyboard event.
Alternatively you can read commands from standard input and then execute a proper function.
