JLabel placement help

Question

I am making a java game, and i have managed to put two squares on my panel. The first sqaure is the player which moves up and down and the other square/s appear from the right and then move to the left (point of the game being the player should avoid on coming blocks).
like I said I have put these blocks on the screen but I cant place them where I want.
Here is the class that creates the "player" (the on coming blocks is in another class with the same code except the ive set the color differnetly).
public class Player extends JPanel{
     int row = 20;
     int col = 20;
     Player()
          JLabel[][] jPan = new JLabel[row][col];
          this.setBackground(Color.GREEN);
          for (int x = 0 ; x < row; x++)
               for (int y = 0; y < col; y++)
                   jPan[x][y] = new JLabel();
                   this.add(jPan[x][y]);
                   this.setPreferredSize(new Dimension(20,20));                  
}and this goes into the constructor in another class
public class Game extends JPanel {
private Player player = new Player();
private Blocks block = new Blocks();
Game()
    this.add(player, BorderLayout.PAGER_START);
    this.add(block, BorderLayout.PAGE_START);
    this.setBackground(Color.BLACK);
    this.setPreferredSize(new Dimension(500,500));
}So can any one show me how to place my squares where I want them?
Also where is the best place to put the keylistener for the player, inside the same class or in another class?

When you want to place your "item" you shoud use one of suitable Layout Manager. Well actually you can use a lot of them . If you still have any problem you can use NetBeans in Free Design mode.
This lauout enables you to lay out your form using visual guidelines that automatically suggest optimal alignment and spacing of components
