Kali ini saya akan membagikan tentang aritmatika, yaitu persamaan kuadrat pada pemrograman java, .
Silahkan dicoba, .
import java.util.Scanner;
public class QuadraticEquation {
public static void main(String[] iriahus) {
@SuppressWarnings("resource")
Scanner s = new Scanner(System.in);
System.out.print("Enter a, b, and c: ");
double a = s.nextDouble();
double b = s.nextDouble();
double c = s.nextDouble();
double D = b * b - 4 * a * c;
double SqrtD = Math.sqrt(D);
double x1 = (-b + SqrtD) / (2 * a);
double x2 = (-b - SqrtD) / (2 * a);
if (D == 0) {
System.out.println("Discriminant is 0.\n" +
"The roots are twins, that is " + x1);
} else if (D > 0) {
System.out.println("Discriminant is greater than 0.\n" +
"The roots are " + x1 + " and " + x2);
} else {
System.out.println("Discriminant is less than 0.\n" +
"The equation has no real roots.");
}
}
}
Semoga bermanfaat, . .
