Java program to find the roots of a quadratic equation

  1. Calculate the determinant value (b*b)-(4*a*c).
  2. If determinant is greater than 0 roots are [-b +squareroot(determinant)]/2*a and [-b -squareroot(determinant)]/2*a.
  3. If determinant is equal to 0 root value is (-b+Math.sqrt(d))/(2*a)

How do you multiply pi in Java?

To get the area, we need to multiply pi times the radius squared.



An Example

  1. import java. lang. Math. *;
  2. public class Pie {
  3. public static void main(String[] args) {
  4. //radius and length.
  5. double radius = 5;
  6. double len = 15;
  7. // calculate the area using PI.
  8. double area = radius * radius * Math. PI;

How do you create a floor in Java?

floor(double a) returns the largest (closest to positive infinity) double value that is less than or equal to the argument and is equal to a mathematical integer. Special cases: If the argument value is already equal to a mathematical integer, then the result is the same as the argument.

How can I get log in Java?

The java. lang. Math. log(double a) returns the natural logarithm (base e) of a double value.

  1. If the argument is NaN or less than zero, then the result is NaN.
  2. If the argument is positive infinity, then the result is positive infinity.
