推荐答案

keyPressed.按下可以转换为Unicode字符的键时，将触发keyTyped.例如，如果按住Shift键，则按"a"会告诉keyTyped您键入了大写字母A，而keyPressed只会得到"a"键，没有大写字母或小写字母.您无法从keyPressed调用event.getKeyChar()，因为没有与事件关联的键字符.字符仅来自keyTyped.

keyPressed is fired whenever any key press occurs. keyTyped is fired when a key is pressed that can be converted into a unicode character. If the shift key is down, for example, pressing "a" will tell keyTyped that you typed a capital A, and keyPressed will just get the "a" key, without capital or lowercase designations. You cannot call event.getKeyChar() from keyPressed, because there is no key char associated with the events. Characters only come from keyTyped.

基本思想是keyTyped用于查找键入的字符，而keyPressed用于获取原始按键.

The basic idea is that keyTyped is used to find characters that are typed, and keyPressed is used for obtain raw key presses.
