RE: printing numbers in spiral shape
One of possible solutions:

public class NumberSpiralShape {

/**

* @param args

*/

public static void main(String[] args) {

// TODO Auto-generated method stub

 

int n = 3, i, side = n, x=0, y=0;int tab [][]= new int [n][n];

 

i=n*n;

while(i>=1){for(int j=0; j<side; j++)

tab[x][y++] = i--;

x++;

y--;

if(i>=1){for(int j=0; j<side-1; j++)

tab[x++][y] = i--;

x--;

y--;

}

if(i>=1){for(int j=0; j<side-1; j++)

tab[x][y--] = i--;

x--;

y++;

}

if(i>=1){for(int j=0; j<side-2; j++)

tab[x--][y] = i--;

y++;

x++;

side=side-2;

}

}

//print

for(i=0; i<n; i++){

for(int j=0; j<n; j++)System.

out.print(tab[i][j] + " ");System.out.println("n");

}

}

}
