Note: (Restricted functionality due to obvious reasons!)
Minimal Code ( Raw-View ) :
abstract class Calc
{
int add(int a, int b) // Complete method
{
return a+b;
}
abstract double div(int a, int b); // Incomplete method
}
class CCalc extends Calc
{
double div(int a, int b)
{
return a/b;
}
}
class AbstractCalc
{
public static void main(String z[])
{
int ad1=23, ad2=64, d1=290, d2=32;
CCalc obj = new CCalc();
System.out.println("Sum ("+ad1+"+"+ad2+") = "+obj.add(ad1,ad2));
System.out.println("Div ("+d1+"/"+d2+") = "+obj.div(d1,d2));
}
}
