Write an object oriented program to find area and perimeter of rectangle.

object oriented program to find area and perimeter of rectangle in java / Write an object oriented program in java to find area and perimeter of rectangle.

Objectives of Object oriented Programming Language

• In object oriented programming, program is divided into small parts called objects.
• Object oriented programming follows bottom up approach.
• Adding new data and function is easy.
• Object oriented programming provides data hiding so it is more secure.
• Object oriented programming is based on real world.

Answer :

public class AreaAndPerimeter {
    private double l, b;
    public AreaAndPerimeter(double l, double b){
        this.l = l;
        this.b = b;
    }
    public double area(){
        return l*b;
    }
    public double perimeter(){
        return 2*(l+b);
    }
    
    public static void main(String[] args) {
     AreaAndPerimeter rectangle = new AreaAndPerimeter(2,4); 
        System.out.println("Area of rectangle is : "+ rectangle.area());
         System.out.println("Perimeter of rectangle is : "+ rectangle.perimeter());
    } 
}

Output of the Program :

run:
Area of rectangle is : 8.0
Perimeter of rectangle is : 12.0
