System.out.println("Your sum is :" +x);
}
}
public class C_inhritance extends C_parent
{
public void sub(int c, int d)
{
x = d-c;
System.out.println("Your Difference is :" +x);
}
public static void main(String args[])
{
int a = 10;
int b = 20;
C_inhritance alpha = new C_inhritance();
alpha.sum(a,b);
alpha.sub(a,b);
}
}
