Demo Code



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

        double b = 20.0;
        double c = 5.0;

        double dis = b * b - (4 * c);
        double sq = Math.sqrt(dis);
        double root1 = (-b + sq) / 2.0;

        double root2 = (-b - sq) / 2.0;
        System.out.println(root1 + "   " + root2);
        System.out.println(Math.sqrt(2) * Math.sqrt(2));
        if ((int) (Math.sqrt(2) * Math.sqrt(2)) == 2) {
            System.out.println("prin");
        }/* w  ww . j a  v  a 2 s . c  om*/
