Question

我目前正在开发一个数独项目，而且我已经接近完成但我的部分代码存在问题（抱歉变量名称是法语），其中二维数组的行和列索引已经以某种方式进行了交换，我似乎无法找到它的来源。这是数组声明：

int[][]sdkGrid = {
            {5,3,0,0,7,0,0,0,0},
            {6,0,0,1,9,5,0,0,0},
            {0,9,8,0,0,0,0,6,0},
            {8,0,0,0,6,0,0,0,3},
            {4,0,0,8,0,3,0,0,1},
            {7,0,0,0,2,0,0,0,6},
            {0,6,0,0,0,0,2,8,0},
            {0,0,0,4,1,9,0,0,5},
            {0,0,0,0,8,0,0,7,9}};

以下是以某种方式交换两个索引的代码：问题是我不知道两个索引的交换位置。

public class FenetreGrille extends JFrame implements ActionListener{

public final int [][] NOMBRES_DEBUT;
public int [][] GRILLE_MODIF = new int[9][9];

public final int COTEGRILLE ;

    COTEGRILLE = TAILLE * TAILLECASE;
    //this.setUndecorated(true); //Remove Title Bar AND EXIT BUTTON SO ADD ONE!!!!!
    this.setAlwaysOnTop(true); //This is always on top 
    this.setResizable(false);
    Toolkit tk = Toolkit.getDefaultToolkit();

Answer 1

我认为你的违规行是：

cases[li][col].setBounds(li*TAILLECASE,col*TAILLECASE,TAILLECASE,TAILLECASE);

要修复，请将其更改为：

cases[li][col].setBounds(col*TAILLECASE,li*TAILLECASE,TAILLECASE,TAILLECASE);

setBounds参数是setBounds（x，y，width，height）。 li（垂直线索引）应对应于y，col应对应于x坐标。

我在GUI中管理这样的数组时使用的一种编码实践是明确地命名我的迭代变量x和y，这样我就不会感到困惑。
