Proposed exercise
Create a project named "Tables2", based on the "Tables" project.
In it, create a class "CoffeeTable" that inherits from "Table". Its method “ShowData", besides writing the width and height, must display "(Coffee table)."
Create an array that contains 5 tables and 5 coffee tables. The tables must have random sizes between 50 and 200 cm, and the coffee tables from 40 to 120 cm. Show all their data.
Output
Solution
using System;
namespace Tables2
{
class CoffeeTable : Table
{
public CoffeeTable(float width,float height)
{
this.width = width;
this.height = height;
}
public override void ShowData()
{
Console.WriteLine("(Coffee table) Width: {0}, Heigth: {1}", width, height);
}
}
class Table
{
protected float width, height;
public Table()
{
}
public Table(float width, float height)
{
this.width = width;
this.height = height;
}
public float Width
{
set { width = value; }
get { return width; }
}
public float Height
{
set { height = value; }
get { return height; }
}
public virtual void ShowData()
{
Console.WriteLine("Width: {0}, Heigth: {1}", width, height);
}
}
