Posted 5 Feb 2013

i have tried changing the code to this... and i ended up with this error

error 39 ".class" expect
rational rational1 = new Rational(double num1,double den1);

I am guessing that this didn't even fix the original error message

``` System.out.print("Please enter the denominator for the frist fraction\n");
den1 = input.nextDouble();

Rational rational1 = new Rational(double num1,double den1);

```

fix the code, so i don't get any errors, when I go and compile the code, but when I go to run the program I don't get any out put I think I am stuck in some sore of loop and it is not getting to the printboard method.
```public class EightQueens
{
public static  void main (String args []) // main method
{
int size = 8;
int [] board = new int [size];
int  y =0;
board[0] = 1;
while (y >=0)
{
board[y]++;
}
while ((board[y]< 8) && (solveQueens( y, board)))// int [])));
if (board[y] < 8)
{
if( y < 7)
{
board[++y]=1;
}
else
{
displayBoard( board);
}
// else
// {
//   y--;

// }
}
}//  end main

private static boolean solveQueens(int y,int[] board)
{
int x = board[y];
//system.out.printf (" in method solvequeens %d",x);

for (int i = 1;i < x; i++)
{
int t = board[y-1];
if (t==x || t==x - i || t ==x +1)
{
return true;
}
}

```

sorry if you find this rude, but have you ever programmed in Java before?

Your method expects an array, but you call it without one on line 24.

no i don't find it very rude.. I am very new to java I am just starting my second java class. I would rather be learning MCSA... but I am trying my best

i was wrong the error is setting up the indexing for the array.
" int max = number; " get me an error message
but if i do
" into max = 71" a limit in the length of the array the program work
just fine
