How to press Enter key using Java?

Question

I want to press Enter Key when a new window pop up for example for downloading a file. I have to press OK button.

So I tried the following code:

Robot r = new Robot();
r.keyPress(KeyEvent.VK_ENTER);
r.keyRelease(KeyEvent.VK_ENTER);

This is just ignoring. Do you have any idea. Thank you

Do you want to simulate an 'Enter' Key press, or do you want to do something when the user physically presses 'Enter'? — Sam I am says Reinstate Monica, May 22 '14 at 15:49

For which purpose? Depending on that the solution may vary. Do you want to send an `Enter`-key event to the OS such that the application which has currently focus can use it, for example to create a new line in the text editor that currently has focus? Or do you want to press some buttons in your **Java swing application** or stuff like that? Is the key-event supposed to leave your application (getting send to the OS)? — Zabuzard, Aug 15 '17 at 19:57
I think anubian already answered in his comment. this seems to be a copied/duplicate question. And yes question is also incomplete. — Acewin, Aug 15 '17 at 19:59
If you want to use Robot, you first need to (somehow) set the focus on the OK button before you actually press Enter. Didn't use robot for a while so I don't know how of the top of my head — Bentaye, Nov 13 '19 at 09:17

This code simulates pressing the Enter Key:

    Scanner keyboard = new Scanner(System.in);
    keyboard.nextLine();

Depending on the application of OP this answer is not necessarily correct. Your code sends a *new-line* command to the channel connected to the Java application via `System.in`. That could be a **console** like Windows *cmd* or nobody in case of **javaw**. It does not emulate pressing the *Enter*-key on the keyboard. For example to create a new line in a text editor that currently has focus by the OS. – Zabuzard Aug 15 '17 at 19:53
