NOW,WRITE A JAVA PROGRAM THAT USES THE CONCEPT OF ADSTRACT CLASS TO STORE AND DISPLAY THE DETAILS OF FURNITURE ITEMS.


ANSWER

public adstract class Furniture {

protected String color;
protected int width;
protected int height;
public adstract void accept();
public adstract void display();
}
   class chair extends Furniture {
private int numOf_legs;

public void accept() {

colour = "Brown"
width = 36;
height = 48;
numOf_legs = 4;
}
  public void display()    {
System.out.println("DISPLAYING VALUE FOR CHAIR");
system.out.println
("==================================");
System.out.println("Color is" + color);
System.out.println("Width is" + width);
System.out.println("Height is" + height);
System.out.println("Number of legs is" + numOf_legs);
System.out.println(" ");
}
}

class Bookshelf extends Furniture {

private int numOf_shelves;

public void accept()  {

colour ="Black";
width = 72;
height = 84;
numOf_shelves = 4;
}
public void display ()  {
System.out.println("DISPLAYING VALUES FOR BOOKSHELF")
System.out.println
("===================================");

System.out.println("Color is" + color);
System.out.println("Width is" + width);
System.out.println("Height is" + height);
System.out.println("Number of shelves is" + numOf_shelves);
System.out.println(" ");
}
}

class FurnitureDemo  {
public static void main(String[] args)   {
bookShelf b1 = new BookShelf();
b1.accept();
b1.display();


Chair c1 = new Chair ();
c1.accept();
c1.display();
