When pressing the W button using the Robot class, the character does not move forward, what's the problem?

Question

Java

To get acquainted with the Robot class, I decided to make a program that would control a character from the Minecraft game, but unfortunately this code does not work in the game.
The letter is printed in a notebook, but it is not possible to make the character from the game walk(

import java.awt.*;
import java.awt.event.KeyEvent;

public class Main {
    public static void main(String[] args) {
        try {
            Robot robot = new Robot();
            robot.keyPress(KeyEvent.VK_W);
            robot.delay(1000);
            robot.keyRelease(KeyEvent.VK_W);
        } catch (AWTException e) {
            e.printStackTrace();
        }
    }
}
