How can I make Robot type a `:`?
提问by Eric Bautista
I want to type :using Java Robot. However, I'm getting an IllegalArgumentException. My code is:
我想:使用 Java Robot打字。但是，我得到了一个IllegalArgumentException. 我的代码是：
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_COLON);
robot.keyRelease(KeyEvent.VK_COLON);
robot.keyRelease(KeyEvent.VK_SHIFT);
The exception is:
例外是：
java.lang.IllegalArgumentException: Invalid key code.].
I also tried with:
我也试过：
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_SEMICOLON);
robot.keyRelease(KeyEvent.VK_SEMICOLON);
robot.keyRelease(KeyEvent.VK_SHIFT);
How can I solve this problem?
我怎么解决这个问题？

try with this code :
尝试使用此代码：
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_SEMICOLON);
robot.keyRelease(KeyEvent.VK_SEMICOLON);
robot.keyRelease(KeyEvent.VK_SHIFT);
As with the keyboard you enter : when you press shift + ;. the same you need to simulate.
与您输入的键盘一样：当您按下 shift + ; 时。与您需要模拟的相同。
Try running this code just to try out which works fine with above answer:
尝试运行此代码只是为了尝试使用上述答案可以正常工作：
public class Test {
public static void main(String[] args) {
Robot robot;
try {
robot = new Robot();
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_SEMICOLON);
robot.keyRelease(KeyEvent.VK_SEMICOLON);
robot.keyRelease(KeyEvent.VK_SHIFT);
} catch (AWTException e) {
// TODO Auto-generated catch bloc
e.printStackTrace();
}
}
}

Unfortunately, Java Robotclass relies on a platform specific implementation of an undocumented interface called java.awt.peer.RobotPeer. The platform specific implementation decides what key press events are legal or illegal.
不幸的是，JavaRobot类依赖于一个名为java.awt.peer.RobotPeer. 平台特定的实现决定了哪些按键事件是合法的或非法的。
On my windows XP box, this works fine:
在我的 Windows XP 机器上，这很好用：
public static void main(final String[] args) throws InterruptedException, IOException {
Robot robot;
try {
robot = new Robot();
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_SEMICOLON);
robot.keyRelease(KeyEvent.VK_SEMICOLON);
robot.keyRelease(KeyEvent.VK_SHIFT);
} catch (final AWTException e) {
// TODO Auto-generated catch bloc
e.printStackTrace();
}
}
On a different platform you may want to try:
在不同的平台上，您可能想尝试：
public static void main(final String[] args) throws InterruptedException, IOException {
Robot robot;
try {
robot = new Robot();
robot.keyPress(KeyEvent.VK_COLON);
robot.keyRelease(KeyEvent.VK_COLON);
} catch (final AWTException e) {
// TODO Auto-generated catch bloc
e.printStackTrace();
}
}

try this code ;), maybe it helps (using ascii code alt+5+8=:):
试试这个代码；)，也许它有帮助（使用 ascii 代码 alt+5+8=:)：
robot9.delay(20);
robot9.keyPress(KeyEvent.VK_ALT);
robot9.delay(20);
robot9.keyPress(KeyEvent.VK_NUMPAD5);
robot9.keyRelease(KeyEvent.VK_NUMPAD5);
robot9.delay(20);
robot9.keyPress(KeyEvent.VK_NUMPAD8);
robot9.keyRelease(KeyEvent.VK_NUMPAD8);
robot9.delay(20);
robot9.keyRelease(KeyEvent.VK_ALT);
robot9.delay(20);

This also seems to be language dependent. On a German keyboard, using the combination of VK_SHIFTand VK_PERIODworked.
这似乎也取决于语言。在德语键盘，使用的结合VK_SHIFT和 VK_PERIOD合作。

Someone build a KeyboardKeys class and published it here in SO. it′s at https://stackoverflow.com/a/20979488/7069565. In a nutshell, he types every character as an Alt + Number combination.
有人构建了一个 KeyboardKeys 类并将其发布在 SO 中。它位于https://stackoverflow.com/a/20979488/7069565。简而言之，他将每个字符键入为 Alt + Number 组合。
回答by Saclyr Barlonium
Semicolon is an "upercase leter", that is, you only get it with the combination of Keys
分号是一个“大写字母”，也就是说，你只有用Keys的组合才能得到它
Shift+Coma
Shift+昏迷
Try this:
试试这个：
robot = new Robot();
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_COMMA);
//Since you have the Shift pressed it will generate a semi colon.
robot.keyRelease(KeyEvent.VK_COMMA);
robot.keyRelease(KeyEvent.VK_SHIFT);
I hope I have helped.
我希望我有所帮助。
Have a nice day. :)
祝你今天过得愉快。:)

Try This Code
试试这个代码
case KeyEvent.VK_SEMICOLON:
if((event.getModifiers() & KeyEvent.KEY_PRESSED)!=0)
System.out.println(":");
else
System.out.print(";");
break;

I don't know about Java Robots, but if you're using shift, shouldn't you then type semicolon, because shift + semicolon = colon. So it's probably an illegal argument because colon isn't a key, semicolon is.
我不了解 Java Robots，但是如果您使用 shift，那么您不应该输入分号，因为 shift + 分号 = 冒号。所以这可能是一个非法参数，因为冒号不是键，分号才是。
