Question

我无法弄清楚如何从其测试文件中编写此代码。

public class MineNeighbourTest
{
    private MineWorld world; 
    private Position  position;
    private MineNeighbour neighbour;
    private MineNeighbour bigNeighbour;

    /**
     * Default constructor for the test class.
     */
    public MineNeighbourTest()
    {

    }

    /**
     * Sets up the test fixture.
     *
     * Called before every test case method.
     */
    @Before
    public void setUp()
    {
        world    = new MineWorld(6, 6);
        position = new Position(world, 3, 1); 
        // create a field that has 4 mines in the neighbourhood 
        neighbour    = new MineNeighbour(position, 4);
        // create a field that has 8 mines in the neighbourhood
        bigNeighbour = new MineNeighbour(position, 8);
    }

    /**
     * Tears down the test fixture.
     *
     * Called after every test case method.
     */
    @After
    public void tearDown()
    {
        world        = null;
        position     = null;       
        neighbour    = null;
        bigNeighbour = null;
    }


    /**
     * Test of getNeighbouringMines method, of class MineNeighbour.
     */
    @Test
    public void testGetNeighbouringMines() 
    {
        assertEquals(4, neighbour.getNumNeighbouringMines());
        assertEquals(8, bigNeighbour.getNumNeighbouringMines());
    }


    /**
     * Test of getStringRepresentation method, of class MineNeighbour.
     */
    @Test    
    public void testGetStringRepresentation() 
    {
        assertEquals("4", neighbour.getStringRepresentation());
        assertEquals("8", bigNeighbour.getStringRepresentation());
    }    

}

这是我写的：

public class MineNeighbour extends Occupant
{
    private Position pos; 

    public MineNeighbour(Position neighbour, Position bigNeighbour) { 
        super(neighbour);
    } 
    public Position getNeighbouringMines() { 
        return neighbour; 
        return bigNeighbour; 
    }
    @Override
    public String getStringRepresenation() { 
        return getNeighbouringMines();
    }
}

我需要使用getStringRepresentation()和neighbour的其他字段将bigNeighbour覆盖为4＆amp; 8，我不太了解{{1}给我的信息}}。

我的乘员班：

MineNeighbourTest

}

Answer 1

public class MineNeighbour extends Occupant
 {
   private int mines;

  public MineNeighbour(Position neighbour, int mines) { 
    super(neighbour);
    this.mines = mines;
  } 

  public Position getNeighbouringMines() { 
    return mines;
  }

  @Override
  public String getStringRepresenation() { 
    return Integer.toString(mines);
  }
}

我应该如何覆盖字符串
