如何传递Java方法参数以获得正确的JLabel水平对齐

JLabel label = new JLabel("Hello World");

label.setHorizontalAlignment(JLabel.CENTER);

frame.add(label);

import javax.swing.JFrame;
import javax.swing.JLabel;

public class Main {
    public static void main(String[] args) {
        JFrame frame = new JFrame("JLabel Horizontal Alignment");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
        JLabel label = new JLabel("Hello World");
        label.setHorizontalAlignment(JLabel.CENTER);
        
        frame.add(label);
        frame.pack();
        frame.setVisible(true);
    }
}
