Question

Below is a java program to find roots of quadratic equation. Please explain each line of code if what it does in the program when executed.

Example: Java Program to Find Roots of a Quadratic Equation

  1. public class Main {
  2.  
  3. public static void main(String[] args) {
  4. double a = 2.3, b = 4, c = 5.6;
  5. double root1, root2;
  6. double determinant = b * b - 4 * a * c;
  7.  
  8. if (determinant > 0) {
  9. root1 = (-b + Math.sqrt(determinant)) / (2 * a);
  10. root2 = (-b - Math.sqrt(determinant)) / (2 * a);
  11. out.format("root1 = %.2f and root2 = %.2f", root1, root2);
  12. }
  13. else if (determinant == 0) {
  14. root1 = root2 = -b / (2 * a);
  15. out.format("root1 = root2 = %.2f;", root1);
  16. }
  17. else {
  18. double real = -b / (2 * a);
  19. double imaginary = Math.sqrt(-determinant) / (2 * a);
  20. out.format("root1 = %.2f+%.2fi", real, imaginary);
  21. out.format("\nroot2 = %.2f-%.2fi", real, imaginary);
  22. }
  23. }
  24. }
