[SOLVED] what error do i have?

[PureAwesomeness]

variable a might not have been initialized
if ((12000 <= a )&&(a < 12321)){
^
what is this mean?

public class tt{
	public static void main(String[]args){

	int n = 1;

	double a;

	while ( n < 999)

		 a = Math.pow(n, 2);

		if ((12000 < a )&&(a < 12321)){

			System.out.println("The smallest n such that n^2 > 12,000 is " + n);
}
		n++;

	}
}

im learning about loops at this point.

There is only one variable in that line that trips the error. You have declared the variable, but where have you initialized it -- where have you set its initial value? Bottom line: when declaring variables (not counting variables declared in the class scope), you need to initialize them to something at declaration.

so i need to assign a to something like a number first?

I try the code as posted and after assing a value to the variable a, it still missing the opening and closing brackets {} for the while loop.
