Multilevel inheritance is a java feature where the
properties of a class are inherited by a class which
extends one or more classes which extend its features.
example:

import java.io.*;
class superclass
{
void sum(int x,int y)
{
int add;
add=x+y;
System.out.println("addition="+ add);
}
}

class subclassA extends superclass
{
void subtraction(int a, int b)
{
int sub;
sub=a-b;
System.out.println("subtraction="+sub);
}
}

class subclassB extends subclassA
{
void multiplication(int m, int n)
{
int mult;
mult=m*n;
System.out.println("multipliction="+mult);
}
}

class subclassC extends subclassB
{
public static void main(String arg[])throws IOException;
{
BufferedReader br=new BufferedReader(new
InputStreamReader(System.in));
int p,q;
System.out.println("enter value in p");
p=Integer.parseInt(br.readLine());
System.out.println("enter value in q");
q=Integer.parseInt(br.readLine());
subclassC obj=new subclassC();
obj.multiplication(p,q);
obj.subtraction(p,q);
obj.sum(p,q);
}
}
