Java program to calculate square area and circumference

Following program shows you how to calculate square area and circumference. This program gets square length from user and calculates area and circumference and prints them using following formulas Area = length X length Circumference = 4 X length

import java.util.Scanner;

public class MathGeometry10 {

	public static void main(String[] args) {

		double squareLength;

		Scanner in = new Scanner(System.in);

		System.out.println("Enter length of square:");
		squareLength = in.nextInt();

		double areaOfSquare = squareLength * squareLength;
		System.out.println("Area of square is: " + areaOfSquare);

		double circumferenceOfSquare = 4 * squareLength;
		System.out.println("Circumference of square is: " + circumferenceOfSquare);

	}
}

Output:

Enter length of square:
5
Area of square is: 25.0
Circumference of square is: 20.0
