Java Program with a class Rectangle with the data fields width, length, area and colour

Question

The length, width and area are of double type and colour is of string type. Create two objects of Rectangle and compare their area and colour. If the area and colour both are the same for the objects then display “Matching Rectangles”, otherwise display “Non-matching Rectangle”

Answer 1

Program Code

import java.io.*; import java.util.*; class Rect {   double width,length,area;   String color;   Scanner sc=new Scanner(System.in);    Rect()    {      System.out.print("Enter the length: ");    length=sc.nextDouble();    System.out.print("Enter the width: ");    width=sc.nextDouble();     System.out.print("Enter the color: ");     color=sc.next();     area=length*width;     System.out.println("Area of Rectangle: "+area);    } } class Demo {    public static void main(String arg[])    {    System.out.println("First Rectangle: ");    Rect r1=new Rect();    System.out.println("Second Rectangle: ");    Rect r2=new Rect();    if(r1.area==r2.area && r1.color.equals(r2.color))           System.out.println("Matching Rectangle ");    else           System.out.println("Non Matching Rectangle ");    } }

Output

First Rectangle: Enter the length: 10.22 Enter the width: 12.22 Enter the color: blue Area of Rectangle: 124.88840000000002 Second Rectangle: Enter the length: 12.22 Enter the width: 10.22 Enter the color: blue Area of Rectangle: 124.88840000000002 Matching Rectangle
