How to get the center of the screen and put the mouse cursor there in java?

Question

Java

Hello! I study java, I train with swing, awt. A simple program, by pressing a button, the cursor should move to the center of the screen. I calculate the center of the screen like this

Dimension sSize = Toolkit.getDefaultToolkit ().getScreenSize ();
      int h = sSize.height;
      int w = sSize.width;

I divide the received values ​​​​by two and transfer them

Robot robot = new Robot();
      robot.mouseMove(x, y);

But the cursor does not move to the center, but to the bottom edge of the screen. Tell me, what could be the error, or maybe there is some ready-made method for calculating the center?

Part of the code on the topic

class ButtonListener implements ActionListener {
    public void actionPerformed(ActionEvent event) {
      Dimension sSize = Toolkit.getDefaultToolkit ().getScreenSize ();
      int h = sSize.height/2;
      int w = sSize.width/2;
      System.out.println("H = " + h + " W = " + w);
      mouseMoveGo(h, w);
      frame.remove(button);
      frame.add(label);
      frame.validate();
      frame.repaint();
      
      
    }
  }
  
  public void mouseMoveGo(int x, int y) {
    try {
      Robot robot = new Robot();
      robot.mouseMove(x, y);
      System.out.println("X = " + x + " Y = " + y);
    } catch (Exception ex) {ex.printStackTrace();}
    
  }

Thanks in advance!

You have the following problem:
You call the method with the following parameters mouseMoveGo(Height, Width).
And in the method itself, you use the parameters in reverse order (Width, Height).
