How do I rotate a graphics object, without changing it's location?

I got the following code:

import java.awt.*;
import javax.swing.*;

public class GraphicPanel extends JPanel {

    public void paintComponent(Graphics g){

        super.paintComponent(g);
        Graphics2D g2d = (Graphics2D) g;

        g2d.setFont(new Font("Arial",Font.BOLD,24));
        g2d.drawString("A",300,250);
        g2d.rotate(45 * Math.PI/180);
        g2d.drawString("B",300,250);

    }

}

It should rotate B and put it in the same place A is, but for some reason, B apears at a totally different location.

Pretty sure I understand why that is. It's because the entire coordination system is manipulated when scaling, rotating etc (am I correct?)

Anyway, I'd like to know how to rotate or scale an object, and still have it appear where it was before. For example in a game that keeps updating and displaying itself every 10 milliseconds, where a sprite is being rotated, but still stays where it was 10 millisceonds before.

EDIT: Tried to search Google beforehand, guess the wording for this question is kind of tricky because I found nothing helpful.

Thanks a lot :)
