Area of a triangle in Java

Question

I want to find the area of a triangle using heron's formula

Answer 1

import java.util.Scanner;

import java.lang.Math;

 class AreaFormula

{

    double area; double s;

    public double findArea(double sideA, double sideB, double sideC)

    { 

        s = 0.5 * (sideA + sideB + sideC);

        area = Math.sqrt(s*(s-sideA)*(s-sideB)*(s-sideC));

        System.out.println("The area of the triangle is " + area);

        return area;

    }

}

public class Main {

    public static void main(String[] args) {

        AreaFormula triangle = new AreaFormula();

        double sideA,sideB,sideC; 

        Scanner inputTriangle = new Scanner(System.in);

        System.out.println("Please enter triangle side A");

        sideA = inputTriangle.nextDouble();

        System.out.println("Please enter triangle side B");

        sideB = inputTriangle.nextDouble();

        System.out.println("Please enter triangle side C");

        sideC = inputTriangle.nextDouble();

        triangle.findArea(sideA, sideB, sideC);

        

    }

}
