I've been looking for the way but they all throw me a mistake, I'd like you to help me with this. I'm doing a minesweeper and I need to leave a caution flag when I right click.

You can do it by adding a ActionListener and check the modifiers:

    boton.addActionListener(new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent e) {
            if ((e.getModifiers() & 4) !=0){
                 // boton derecho
            }
        }
    });

Left button would be getModifiers() & 16 and the middle button getModifiers() & 8 .

Alternatively you could use a MouseListener :

    MouseListener mouseListener= new MouseListener() {

        @Override
        public void mouseReleased(MouseEvent e) {
        }

        @Override
        public void mousePressed(MouseEvent e) {
        }

        @Override
        public void mouseExited(MouseEvent e) {
        }

        @Override
        public void mouseEntered(MouseEvent e) {
        }

        @Override
        public void mouseClicked(MouseEvent e) {
            System.out.println(e.getButton());
            // MouseEvent.BUTTON3 es el boton derecho
        }
    };
    boton.addMouseListener(mouseListener);

If you use onMousePressed and onMouseReleased you can show your information only while the button is pressed.
