How to make a class extending a jLabel so that it appears as a JLabel in my main class?

So, essentially I'm making memory. I have a tile class, which at this point will only have a number, and a boolean (to show if it is flipped or not). I made duplicates of all the numbers as Tile objects and randomized them, and in turn added them to my layout.

Basically, I need them to show up on my screen as JLabels, and I'm not exactly sure how to do this? Should I be extending something else, or do something special in my Tile class? Or is it a problem with my logic elsewhere? Here's my Tile class at this point (very little)

PS. I also need to use a timer for the flippy flop

class Tile extends JLabel implements ActionListener{

boolean flipped;
int imageNum;
ImageIcon image;
JLabel card;

Tile(int num, boolean f)
{
    imageNum=num;
    flipped=f;
    card=new JLabel(""+imageNum);
}
public void flipCard()
{

}

public void actionPerformed(ActionEvent a)
{

}

Any help would be greatly appreciated! EDIT:

Here's the main class where I try to add my tiles

JPanel gridPanel = new JPanel(new GridLayout(gridSize, gridSize));
    Tile[][]tiles=new Tile[(gridSize*gridSize)/2][2];
    boolean[][]tilePlaced=new boolean[(gridSize*gridSize)/2][2];
    JLabel[][] cardsOnGrid = new JLabel[gridSize][gridSize];
    for(int i=0;i<gridSize;i++)
    {
        for(int j=0;j<gridSize;j++)
            cardsOnGrid[i][j]=new JLabel("");
    }
    for(int i=0; i<((gridSize*gridSize)/2);i++)
    {
        tiles[i][0]= new Tile(i, true);
        tiles[i][1]= new Tile(i, true);
        tilePlaced[i][0]=false;
        tilePlaced[i][1]=false;
    }

    for(int i=0; i<gridSize;i++)
    {
        for(int j=0;j<gridSize;j++)
        {
            int tileNum = tileRandom(gridSize);
            int tileNumVer = (int)Math.floor(Math.random()*2);
            while(tilePlaced[tileNum][tileNumVer]==true)
            {
                tileNum = tileRandom(gridSize);
                tileNumVer = (int)Math.floor(Math.random()*2);
            }
            gridPanel.add(tiles[tileNum][tileNumVer]);
            tilePlaced[tileNum][tileNumVer]=true;
        }

 Tile(int num, boolean f){
    imageNum=num;
    flipped=f;
    card=new JLabel(""+imageNum);//1. Remove this line and card Label
    super.setText(String.valueOf(num));//ADD This line
 }

Just create Object of Tile

Tile myLabel = new Tile(10,false);//this will create lable

Because your Tile class is subClass of JLabel and no need to create Label in Tile class as Tile itself is a Label.Apart from that you won't get action events for JLabel.It's not a clickable element use MouseListener.
