Java program to find Area of Rectangle

Area of Rectangle in Java - This program will read length and width of the Rectangle and Calculate Area of the Rectangle.

To find Area of the Rectangle - Multiply Rectangle Length with Rectangle Width.

Area of Rectangle using Java program

//Java program to find Area of Rectangle.
 
import java.util.*;
 
public class AreaRectangle{
 
     public static void main(String []args){
        double length,width,area;
         
        Scanner sc=new Scanner(System.in);
         
        //Read Length and Width of Rectangle
        System.out.print("Enter length: ");
        length=sc.nextDouble();
        System.out.print("Enter width: ");
        width=sc.nextDouble();
         
        //Calculate Area 
        area= length*width;
         
        //Print Result
        System.out.println("Area of Rectangle: " + area);    
         
     }
}

Output

    me@linux:~$ javac AreaRectangle.java
    me@linux:~$ java AreaRectangle

    Enter length: 10.2
    Enter width: 20.3 
    Area of Rectangle: 207.06

Using Function/Method

//Java program to find Area of Rectangle.
 
import java.util.*;
 
public class AreaRectangle{
 
    //Function to find Area of Rectangle
    public static double AreaOfRectangle(double l, double w)
    {
        double area;
        area=l*w;
        return area;
    }
     
     public static void main(String []args){
        double length,width,area;
         
        Scanner sc=new Scanner(System.in);
         
        //Read Length and Width of Rectangle
        System.out.print("Enter length: ");
        length=sc.nextDouble();
        System.out.print("Enter width: ");
        width=sc.nextDouble();
         
        //Find Area - Calling Functionn
        area= AreaOfRectangle(length, width);
         
        //Print Result
        System.out.println("Area of Rectangle: " + area);    
         
     }
}
