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。
所以我要调出矩阵。没有任何来自 main.java 的东西。 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

有什么想法吗？
最佳答案
java 中的数组索引是从 0 开始的。
因此，如果您键入 maturix[10][0]，您将访问第 11 个元素。在声明中加 1，public String[][] maturix = new String[11][11];
