How to simulate Keyboard press in java

I want to simulate entering a string (can contain any character) in JTextField. I am using new KeyEventData() for that. But I am not able to determine how to handle characters like {, }, ) etc and also how to append a new character to already entered characters.

Solution

  • You can use Robot for this, as shown in this example. To get {, for example, you'll need to do something like this:

    keyPress(KeyEvent.VK_SHIFT);
keyPress(KeyEvent.VK_OPEN_BRACKET);
keyRelease(KeyEvent.VK_OPEN_BRACKET);
keyRelease(KeyEvent.VK_SHIFT);
