Su Do Ku

I am trying to make a Java version of the game Su Do Ku and I can get one could get all coloums generated (not rows) but the way I currently do it is very unefficent that many times... Any ways to shorten it down and easier to get all boxes, rows, and coloums to work out right...

Java:

public class SuDoKu
{
public static void main (String[] args)
{
int minNumber=1;
int maxNumber=9;
int[] [] board=new int [10][10];
boolean [] vaild= new boolean [9];
int temp;
boolean check=false;

for(int i = 0; i < 9; i++)
   {
         vaild[i]=false;
   }

for(int i = 0; i < 8; i++)
   {
         vaild[i]=false;
   }

   for(int j = 0;j < 9; j++)
   {
   while(check==false)
   {
     temp = (int) (Math.random() * 100) % (maxNumber-minNumber+1) + minNumber;
if(vaild[temp-1] == false)
{
board[j][1]=temp;
vaild[temp-1]=true;
System.out.println(board[j][1]);
check=true;
}
}
check=false;
}

}
}

Have a look here Smile

It's not really a direct answer to your question, but it should give you a few hints on how to continue.

It kinda helps but I am not trying to solve the puzzle, I am trying to make one...

So far, I have got:

Java:

public class SuDoKu
{
public static void main (String[] args)
{
int minNumber=1;
int maxNumber=9;
int[] [] board=new int [10][10];
boolean [] vaild= new boolean [9];
int temp;
int temp1;
boolean check=false;

for(int i = 0; i < 9; i++)
   {
         vaild[i]=false;
   }

   for(int i=0;i<9;i++)
   {
   for(int j = 0;j < 9; j++)
      {
         while(check==false)
         {
temp = (int) (Math.random() * 100) % (maxNumber-minNumber+1) + minNumber;
if(vaild[temp-1] == false)
{
board[j][i]=temp;
vaild[temp-1]=true;
// System.out.print(board[j][i]);
check=true;
}
}
check=false;
}
System.out.println();
for(int a=0;a<9;a++)
{
vaild[a]=false;
}
}
int value=1;

for(int a=0;a<9;a++)
{
for(int b=0;b<9;b++)
{
for(int c=0;c<9;c++)
{
for(int d=0;d<9;d++)
{
while(value==1)
{
if(board[a][c]==board[b][d])
{
for(int i=0;i<9;i++)
      {
         for(int j = 0;j < 9; j++)
               {
                  while(check==false)
         {
      temp = (int) (Math.random() * 100) % (maxNumber-minNumber+1) + minNumber;
if(vaild[temp-1] == false)
{
board[j][i]=temp;
vaild[temp-1]=true;
System.out.print(board[j][i]);
check=true;
}
}
check=false;
}
System.out.println();
for(int e=0;e<9;e++)
{
vaild[e]=false;
}
}
}
for (int f=0;f<9;f++)
{
for(int g=0;g<9;g++)
{
for (int h=0;h<9;h++)
{
for (int o=0;o<9;o++)
{
if(board[f][g]!=board[h][o])
{
value=0;
}
}
}
}
}value=1;
System.out.println();
}
}
}
}
}
}
}

The first set of loops generates inital numbers and the second longer set checks it, I got it to go but it kept on going for an hour to try and generate one board...

holy crap.. umm dont use tabs for indenting.. use spaces, or set your editor such that when you press tab it places 4 spaces or anythign.. also follow the sun java standard of 80 characters per line
