Answer to Question #270934 in Java | JSP | JSF for Aaiza

Question

Construct a class Rectangle. Provide a constructor to construct a rectangle with a

given width and height, member functions get_perimeter and get_area that compute the

perimeter and area, and overload method to resize the rectangle. For example r*factor

(double factor) resizes the rectangle by multiplying the width and height by the given

factor.

Answer 1

SOLUTION

package com.company;

class Rectangle

{

    double width;

    double length;
    //constructoer to set the length and width
    Rectangle()
    {
        this.width = 8;
        this.length = 12;
    }
    //A method to get perimeter
    double perimeter()
    {
        return (width*2)+(length*2);
    }
    //A method to get area
    double area()
    {
        return (width*length);
    }
    //overload the constructor now

    Rectangle(int factor)
    {
        this.width = width * factor;
        this.length = length * factor;
    }


}
public class Main{
    public static void main(String[] args) {
        //create an object of the parameterless constructor
        Rectangle r = new Rectangle();
        System.out.println("The perimeter of the Rectangle is "+r.perimeter());
        System.out.println("The area of the Rectangle is "+r.area());
        Rectangle r2 = new Rectangle(2);
        System.out.println("The perimeter of the Rectangle for r2 is "+r.perimeter());
        System.out.println("The area of the Rectangle for r2 is "+r.area());
            }
}
