Lejos 在初始化矩阵时给出错误

Question

我们正在尝试构建一个机器人，为了让机器人了解他现在的位置，我们将使用矩阵。

所以我正在调用矩阵。 java 没有主线的任何东西。然后尝试使用 initMatrix，它只是给我一个错误。

public class Matrix {

    // Matrix creation
    public String[][] maturix = new String[10][10];
    // Recorded Position of the Robot
    public int x=0;
    public int y=10;
    public int Ox;
    public int Oy;
    public String Orientation = "East"; //Initializing the robot East-oriented to help place Obstacles (either Walls or Sheep) and walking

    public void initMatrix()
    {
        // Summary: E = Empty; G = Sheep; W = Wall; C =  current position; F = Finishing Line; X = Null; U = Unknown


        maturix[10][0] = "S"; //Starting Position
        maturix[10][1] = "U";
        maturix[10][2] = "U";

    }
}

有什么想法吗？

Answer 1

您的矩阵定义为：

public String[][] maturix = new String[10][10];

但这意味着您只能访问 [0,9]（10 个元素）范围内的索引。

您必须定义：

public String[][] maturix = new String[11][11];

Answer 2

java 中的数组索引是从 0 开始的。

因此，如果您键入 maturix[10][0]，您将访问 11th 元素。声明加1，public String[][] maturix = new String[11][11];
