Sudoku-Problemlösungs-Applet-Implementierungscode

Ich habe ein kleines Programm in Java geschrieben, um 9x9-Sudoku-Probleme zu lösen. Es ist kein großes Problem, um allgemeine Probleme zu lösen:

Die laufenden Ergebnisse lauten wie folgt:

package Test;
public class SensibleGame {
 /**
  * @param args
  */
 int[][] mainNumber;
 boolean[][] flagNumber;
 public SensibleGame(int[][] mainNumber)
 {
  this.mainNumber = mainNumber;
  flagNumber = new boolean[9][9];
  for(int i=0;i<9;i++)
  {
   for(int j=0;j<9;j++)
   {
    if(mainNumber[i][j] == 0)
    {
     flagNumber[i][j] = false;
    }
    else
    {
     flagNumber[i][j] = true;
    }
   }
  }
 }
 
 public boolean CheckRow(int i, int j)//检查(i,j)位置的行是否满足数独条件
 {
// 代码省略
   }
 
 public boolean CheckColumn(int i, int j)//检查(i,j)位置的列是否满足数独条件
 {
//代码省略
   }
 
 public boolean CheckRound(int i, int j)//检查(i,j)位置所在的3x3格是否满足数独条件
 {
//代码省略
   }
 
 public void run()//计算方法 穷举填数过程
 {
  int i = 0;
  int j = 0;
  boolean previousFlag = false;
  while(true)
  {
   if(i<0 || i>8 || j<0 || j>8)
   {
    System.out.print("下标越界！");
    return;
   }
   if(previousFlag == false)
