How can I programmatically generate keypress events?
提问by Anubha
What the java program should do is it should trigger keyboard press on some condition without a person pressing a keyboard key. So any program running in windows and in focus which requires keyboard input will get the input without a person actually pressing the keyboard.
java程序应该做的是它应该在没有人按下键盘键的情况下触发键盘按下。因此，任何需要键盘输入的在 Windows 中运行并获得焦点的程序都将在没有人实际按下键盘的情况下获得输入。

I was wondering if there is any method to do this in Java.

Use the Robotclass.
使用机器人类。
Code snippet:
代码片段：
import java.awt.Robot;
import java.awt.KeyEvent;
Robot r = new Robot();
int keyCode = KeyEvent.VK_A; // the A key
r.keyPress(keyCode);
// later...
r.keyRelease(keyCode);
However, if you are trying to automate a task on your computer, I would recommend AutoHotKey. It's dedicated to automating common tasks, so it would be easier to use it instead of Java.
但是，如果您尝试在计算机上自动执行任务，我会推荐AutoHotKey。它致力于自动化常见任务，因此使用它而不是 Java 会更容易。
