  作ったパネルはmain()のところでadd()しています。これを踏まえて、スタートボタンや点数表示などを追加してみてはいかがですか？

 

  ```java

  import java.awt.Color;

  import java.awt.Graphics;

  import java.awt.Point;

  private static NextBlockPanel nextBlockpanel;

 

  // Creates a border around the well and initializes the dropping piece

  well = new Color[12][24];

  for (int i = 0; i < 12; i++) {

  for (int j = 0; j < 23; j++) {

  preparedPiece = createIndex();

  }

  nextBlockpanel.setPiece(

  Tetraminos[preparedPiece][0],

  tetraminoColors[preparedPiece]);

  }

  public static final int WIDTH = 26 * 6;

  public static final int HEIGHT = 26 * 6;

 

  private Color color;

  private Point[] points;

 

  setPreferredSize(new Dimension(WIDTH, HEIGHT));

  }

 

 

  this.points = points;

  this.color = color;

 

  repaint();

  }

 

  if (points == null) return;

 

  g.setColor(color);

  for (Point p : points) {

  }

  }

  }
