setLocation not working on class extending JPanel

I have a class named "Player" which extends JPanel. The class has the attributes x and y (which might be the problem but I can't figure it out). When I run the next code it sets the location of the JPanel to (100, 100):

private void initGamePanel() {
    gamePanel.setBackground(Color.BLUE);
    gamePanel.setVisible(true);
    gamePanel.setLayout(null);

    JPanel jPanel = new JPanel();
    jPanel.setLocation(100, 100);
    jPanel.setSize(100, 100);
    jPanel.setBackground(Color.CYAN);

    gamePanel.add(player);
}

But when I do the same with the "Player" class, the position stays at (0, 0):

private void initGamePanel() {
    gamePanel.setBackground(Color.BLUE);
    gamePanel.setVisible(true);
    gamePanel.setLayout(null);

    player = new Player();
    player.setLocation(100, 100);
    player.setSize(100, 100);
    player.setBackground(Color.CYAN);

    gamePanel.add(player);
}

And another thing: when I set the x and y of player in the constructor, the position is equal to those values.

The class has the attributes x and y (which might be the problem

It could be, especially if you have getX() and getY() methods, since these are already implemented by a JPanel and should not be overridden.

Not sure if you really need the x/y attributes since you can just set the location of the component directly.

If you need these attributes for another reason then they should have a more descriptive name to avoid confusion with the class variables.
