Introduction

This is a tutorial for area of rectangle in java. The program calculates the area and prints it. The program is extendable. Go enjoy the program. Lets begin……

Program for area of rectangle in java.

//import Scanner as we require it.
import java.util.Scanner;

// the name of our class its public
public class RectArea {
//void main
public static void main (String[] args)

//Take input
Scanner input = new Scanner(System.in);
a = input.nextInt();
b = input.nextInt();
//calculate
area = a*b;
//print the area
System.out.println(“Area = “+area);
}
}
