How to simulate keyboard presses in java?

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?

Solution

  • 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();
}
