在另一个具有图像的 JLabel 之上有一个 JLabel

Soo I'm trying to make a board game with GUI. I created a JLabel with the player's name and want to use that as a token. Then I made another JLabel that contains the image of the board. I added both the labels onto a boardPanel and right now, the labels are side by side. How do I make it so that instead of it being side to side, the JLabel w/ name is on the JLabel w/ img?

Is there something I should be considering for the panel that contains the two labels? Like a certain Layout Manager?

[just sections of my code]

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

public class BoardFrame extends JFrame {

   private JPanel mainPanel, boardImgPanel,jPanelSouth,buttonPanel
           ,cardPanel,statsPanel;
   private boardImgLabel;

   Player player1;

   public BoardFrame() {
      //boardPanel and stuff in it
      boardImgPanel = new JPanel();
      boardImgLabel = new JLabel();
      boardImgLabel.setIcon(new ImageIcon("BOARDPICTUREHERE"));
      boardImgPanel.add(boardImgLabel);

      /////////////////////ADDING PLAYERS/////////////////////
      player1 = new Player("Steven", 1,1,1,1,1);
      JLabel player1Label = new JLabel(player1.getPlayerName());
      boardImgPanel.add(player1Label);

      mainPanel = new JPanel(new GridLayout(0, 1));

      add(mainPanel);

   }
}

something like this but obviously instead of a cat, it's the board image, and the text is the player name.

EDIT

I made a class that extends the jpanel and then wanted to add it into the BoardFrame class

import java.awt.BorderLayout;
import java.awt.Color;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JLabel;
import javax.swing.JPanel;

public class BoardPanelNorth extends JPanel {
        File imageFile = new File("....");

        JLabel boardImgLabel = new JLabel();
        Player player1;

        public BoardPanelNorth() {
            setLayout(new BorderLayout());
            try {
                boardImgLabel = new JLabel(new ImageIcon(ImageIO.read(imageFile)));
                boardImgLabel.setLayout(new BorderLayout());

                player1 = new Player("Steven", 1,1,1,1,1);
                JLabel player1Label = new JLabel(player1.getPlayerName());
                player1Label.setFont(player1Label.getFont().deriveFont(128f));
                player1Label.setHorizontalAlignment(JLabel.RIGHT);
                player1Label.setVerticalAlignment(JLabel.BOTTOM);
                player1Label.setForeground(Color.WHITE);

                add(boardImgLabel);
            } catch (IOException ex) {
                ex.printStackTrace();
            }
        }

}

Board Frame class:

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

public class BoardFrame extends JFrame {

   private JPanel mainPanel, boardImgPanel;
   private JSplitPane splitPane;

   public BoardFrame() {

      boardImgPanel = new BoardPanelNorth();


      //split plane
      splitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT, 
         new JScrollPane(boardImgPanel), jPanelSouth);
      splitPane.setDividerLocation(470); //top size
      splitPane.enable(false); //cant adjust


      mainPanel = new JPanel(new GridLayout(0, 1));
      mainPanel.add(splitPane);

      add(mainPanel);

   }
}

Player Steven still does not seem to appear on the map.

You could make use of an OverlayLayout or you could simply add the second JLabel to the first. The trick here though, is to set up a layout manager for the first label.

Beware though, a JLabel only use the icon and text properties its determine the preferred layout size, which could end up truncating it's children
