Java program to calculate triangle area

Following program shows you how to calculate triangle area.
This program gets triangle base and height from user and calculates area and prints it using following formula
Area = base X height / 2

import java.util.Scanner;

public class MathGeometry1 {

	public static void main(String[] args) {

		double triangleBase;
		double triangleHeight;

		Scanner in = new Scanner(System.in);

		System.out.println("Enter the base of triangle:");
		triangleBase = in.nextDouble();

		System.out.println("Enter the height of triangle:");
		triangleHeight = in.nextDouble();

		double areaOfTriangle = (triangleBase * triangleHeight) / 2;
		System.out.println("Area of triangle is: " + areaOfTriangle);

	}
}

Output:

Enter the base of triangle:
2
Enter the height of triangle:
3
Area of triangle is: 3.0
