| Answer | You can offer the best of both worlds, an interface and an
abstract class. Implementors can ignore your abstract class
if they choose. The only drawback of doing that is calling
methods via their interface name is slightly slower than
calling them via their abstract class name.  |

| Answer | Interface is use where we known that all these functions
which are declared in interface is implemented somewhere if
we call that interface.and we can use abstract class where
we don't known how it is implemented in call function.  |

| Answer | If a class has one abstract method ,the class has to be an
abstract class.
Methods can be implemented in abstract class.
Whereas a interface is like a abstract class...the only
difference being that the methods are never implemented in
Interface.  |

| Answer | The string will be rendered correctly if you use the right
font, there is nothing special about barcodes. Google and
