private BoardGame board;
public MovePawnTest() {
board = new BoardGame();
getContentPane().add(board, BorderLayout.CENTER);
}
public static void main(String[] args) {
MovePawnTest movePawnTest = new MovePawnTest();
movePawnTest.setDefaultCloseOperation(MovePawnTest.EXIT_ON_CLOSE);
movePawnTest.setSize(new Dimension(600, 300));
movePawnTest.setLocationRelativeTo(null);
movePawnTest.setVisible(true);
movePawnTest.setExtendedState(MAXIMIZED_BOTH);
}
