[SOLVED] The jlabel can't be positioned as I want

private JLabel basicRule;

public TutorialFrame() {
    setTitle("Tutorial");
    setSize(800, 800);
    setVisible(true);
    setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    setResizable(false);
    
    JLabel basicRule = new JLabel("OneCard Basic Rule");
    basicRule.setBounds(0, 0, 800, 50);
    add(basicRule);
}

I clearly set the position of JLabel called basicRule to (0,0) through basicRule.setBounds (0,0,800,50);. But when it's implemented, it's in the center like a picture. Why isn't the location set?

So, what other methods should we use to set the location as we want? I would appreciate it if you could let me know if you know, how.

Left aligned label in center of height
