java - VK在Java的KeyEvent类中代表什么？

Question

我想知道，VK在java中代表什么？

下面是一个实例代码，目的是让您简要了解它的使用位置:

public void keyPressed(KeyEvent e){ if (e.getKeyCode == KeyEvent.VK_UP) {...}}

Answer 1

这是“虚拟 key ”的简写:

KeyEvent:

Virtual key codes are used to report which keyboard key has been pressed, rather than a character generated by the combination of one or more keystrokes (such as "A", which comes from shift and "a").
