如何在java中模拟键盘按下？

Question

I want to run a java program and have it simulate keyboard presses. So it could for example, type some text on a focused input box. Is this possible?

Answer 1

java.awt.Robot might help.

Here's a simple sample code snippet from Java Tips :

try {
        Robot robot = new Robot();

        // Simulate a mouse click
        robot.mousePress(InputEvent.BUTTON1_MASK);
        robot.mouseRelease(InputEvent.BUTTON1_MASK);

        // Simulate a key press
        robot.keyPress(KeyEvent.VK_A);
        robot.keyRelease(KeyEvent.VK_A);

} catch (AWTException e) {
        e.printStackTrace();
}
