Java program to calculate area of rectangle

In rectangle java program user will be prompted to enter the length and width of a rectangle. Then using input values we calculate the area.

// Area = length * width 

import java.util.Scanner;

public class RectangleArea 
{
   public static void main(String[] args) 
   {
      Scanner sc = new Scanner(System.in);
      System.out.println("Please enter length of rectangle : ");
      double length = sc.nextDouble();
      System.out.println("Please enter width of rectangle : ");
      double width = sc.nextDouble();
      double area = length * width;
      System.out.println("Area : " + area);
      sc.close();
   }
}

Output:

Please enter length of rectangle : 2
Please enter width of rectangle : 5
Area : 10.0


Similarly we can calculate area of rectangle without using scanner class.

import java.util.*;
 
public class AreaRectangle
{ 
   public static void main(String []args)
   {
      double length = 30.0;
double width = 40.0; double area = length * width; System.out.println("Area : " + area); }
}

Output:

Area : 1200.0
