Consider a method with this heading: public static void print Sqrt (double x) The method prints the square root of x to the standard output. Write a reasonable specification for this method and compare your answer to the solution at the end of the chapter. The specification should forbid a negative argument.

public static void printSqrt(double x) {
        double p = 0.001;
        double guess = x / 2;
        while( Math.abs( guess*guess - x ) > p) {
            guess  = ( guess + (  x / guess ) ) / 2;
        }
        float ans = (float) guess;
        System.out.println(ans);
    }
