Java program to calculate parallelogram area

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

import java.util.Scanner;

public class MathGeometry6 {

	public static void main(String[] args) {

		double parallelogramBase;
		double parallelogramHeight;

		Scanner in = new Scanner(System.in);

		System.out.println("Please enter base of parallelogram: ");
		parallelogramBase = in.nextInt();

		System.out.println("Please enter height of parallelogram: ");
		parallelogramHeight = in.nextInt();

		double areaOfParallelogram = parallelogramBase * parallelogramHeight;
		System.out.println("Area of parallelogram is: " + areaOfParallelogram);
	}
}

Output:

Please enter base of parallelogram: 
7
Please enter height of parallelogram: 
9
Area of parallelogram is: 63.0
