Program to calculate the room area and volume to illustrate the concept of single inheritance.


CODE:
class Roomarea 
{
protected double l, b;
Roomarea(double len, double br)
{
l=len;
b=br;
}
void putdata()
{
System.out.println("Area of Room: "+(l*b));
}
}
class Roomvol extends Roomarea 
{
double h;
Roomvol(double len, double br, double he)
{
super(len, br);
h=he; 
}
void putdata()
{
super.putdata();
System.out.println("Volume of Room: "+(l*b*h));
}
}
public class EXP18Q4
{
public static void main(String[] args)
{
Roomvol r1 = new Roomvol(10, 20, 10);
r1.putdata(); 
} }
