使用 Java 机器人时,发送斜杠或反斜杠时会引发异常。
例如:
public void slash() throws AWTException {
Robot rob = new Robot();
rob.keyPress(KeyEvent.VK_SLASH);
rob.keyRelease(KeyEvent.VK_SLASH);
}
public void backSlash() throws AWTException {
Robot rob = new Robot();
rob.keyPress(KeyEvent.VK_BACK_SLASH);
rob.keyRelease(KeyEvent.VK_BACK_SLASH);
}
然后,当我想输入这些时,我使用:
public void type() {
try {
slash();
} catch (AWTException e) { System.out.println("Exception when typing slash."); }
try {
backSlash();
} catch (AWTException e) { System.out.println("Exception when typing back slash."); }
}
我在控制台中收到两条错误消息。顺便说一句,我尝试发送的所有其他击键都工作正常。
我得到以下斜线堆栈跟踪:

反斜杠有效,但也会抛出 IllegalArgumentException:

有什么方法可以发送斜杠和反斜杠按键吗?
