复制粘贴不能使用机器人类：Ctrl + C; 内容没有保存到剪贴板中，但几天前它可以正常工作

Question

    *

Basically i've selected some text and trying to copy it; but below code is not doing Ctrl+C during runtime-nothing is storing into clipboard-however manually i've tried my keys are working fine, but it used to work few days back. Could you please help me on this issue.

        robot.keyPress(KeyEvent.VK_CONTROL);
            Thread.sleep(2000);
                    robot.keyPress(KeyEvent.VK_C);
                    Thread.sleep(2000);
                    robot.keyRelease(KeyEvent.VK_CONTROL);
                    Thread.sleep(2000);
                    robot.keyRelease(KeyEvent.VK_C);

Answer 1

First you need to release the key "C" and then "Control" key.

robot.keyPress(KeyEvent.VK_CONTROL);
Thread.sleep(2000);
robot.keyPress(KeyEvent.VK_C);
Thread.sleep(2000);
robot.keyRelease(KeyEvent.VK_C);
Thread.sleep(2000);
robot.keyRelease(KeyEvent.VK_CONTROL);
