calculate rectangle area and perimeter with java code example
Example 1: Java program to find perimeter of a rectangle
import java.util.Scanner;
public class PerimeterOfRectangleDemo
{
public static void main(String []args)
{
float length, width, perimeter;
Scanner sc = new Scanner(System.in);
System.out.print("Please enter length of rectangle: ");
length = sc.nextFloat();
System.out.print("Please enter width of rectangle: ");
width = sc.nextFloat();
perimeter = 2 * (length + width);
System.out.println("Perimeter of rectangle: " + perimeter);
sc.close();
}
}
Example 2: java program to find perimeter of rectangle
Scanner sc = new Scanner(System.in);
System.out.println("Enter Width of the rectangle: ");
double width = sc.nextDouble();
System.out.println("Enter Height of the rectangle: ");
double height = sc.nextDouble();
sc.close();
double perimeter = 2 * (width + height);
System.out.println("Perimeter of Rectangle: " + perimeter);
