Java 二维对象数组

Question

我有一个带有函数的单元格对象

public class Cell {
    static int X;
    static int Y;
    static int Val = 0;
    static int Player = 0;

    public Cell(int a, int b, int p) {
        // TODO Auto-generated constructor stub
        X = a;
        Y = b;
        Val = 0;
        Player = p;
    }

具有附加函数 updateX、updateY、updateVal、updatePlayer 和各自的 get 函数。它被称为

    Cell[][] grid = new Cell[7][6];
    for(int i = 0; i < 7; i++)
            for(int j = 0; j < 6; j++)
            {
            grid[i][j] = new Cell(i, j, 0);         
            }       
        System.out.println("wasd");
        grid[0][1].updatePlayer(1); 
        grid[0][1].updateVal(1);

        System.out.println("grid[0][1].getval = " + grid[0][1].getVal() + " grid[1][1].getval = " + grid[1][1].getVal());

但是输出是

grid[0][1].getval = 1 grid[1][1].getval = 1

应该是

grid[0][1].getval = 1 grid[1][1].getval = 0

是什么导致了这个错误？

Answer 1

static int X;
static int Y;
static int Val = 0;
static int Player = 0;

这些属性不应该是静态的，下面的代码应该没问题:

int X;
int Y;
int Val;//the default int value is zero 
int Player;
