Question

Write a class named Room that has two fields one for the room’s length and one for the width. The class should have a constructor that sets the length and the width and a method named “getArea” that returns the room’s area (area = ½ length x width). It should also have a method named “isEqual” (with a Room argument) that determines if the two rooms are equal or not. (25 points). Do not write the demo to test this class.

Answer 1

Please find the code below:

Room.java

package classes13;

public class Room {
  
   private double length;
   private double width;
   public Room(double length, double width) {
       super();
       this.length = length;
       this.width = width;
   }
  
   public double getArea(){
       return length*width;
   }
  
   public boolean isEqual(Room m){
       if(length==m.length && width==m.width){
           return true;
       }else{
           return false;
       }
   }

  
   //test code can delete if not needed
   public static void main(String[] args) {
       Room room1 = new Room(20, 30);
       Room room2 = new Room(10, 20);
       System.out.println("Room 1 area : "+room1.getArea());
       System.out.println("Room 2 area : "+room2.getArea());
      
      
   }
}

output:
