Write a program in Java to implement multi level Inheritance
Program:
class
Rectangle
{
double l,b;
Rectangle(double x,double y)
{
l=x;
b=y;
}
double CalArea()
{
return (l*b);
}
}
class Box
extends Rectangle
{
double h;
Box(double x,double y,double z)
{
super(x,y);
h=z;
}
double CalVol()
{
return (l*b*h);
}
}
class
Cube extends Box
{
Cube(double s)
{
super(s,s,s);
}
}
class
Sk11
{
public static void main(String args[])
{
Cube obj1=new Cube(5.5);
double a1= obj1.CalArea();
double v1= obj1.CalVol();
System.out.println("Area= "+a1);
System.out.println("Vol= "+v1);
}
}
Compile:
D:\>javac
Sk11.java
Run:
D:\>java
Sk11
Output:
Area =
35.75
Volume =
268.125
