Hi All,
Please check below points:
1. If i have one interface class and i want to extends interface class so can i extends?
2. If i have one abstract class and i want to implements Abstract class so can i implements?
Thanks & Regards,
Rahul.
Did you try it yourself?
1) Create a class that extends the interface class. Do you notice some issues / errors?
2) Create a class that implements the abstract class. Do you notice some issues / errors?
Dear Mäenpää,
Yes i try it myself and i am getting some error.
But in standard i can see 'RunBaseBatch' class, 'RunBaseBatch' class is a Abstract class but this class is doing extends and implements both ?
Would you mind sharing more details about "some error" (the exact error message would be nice) as well as your code? That would help us understand what might be wrong in your situation.
Thanks!
Interfaces and classes are technically two different things. Interfaces merely describes method that a class may have; they're not classes by themselves.
You can extend (= inherit from) classes, but not interfaces. You can implement interfaces.
Note that a class always has just a single parent class, but it can implement any number of interfaces.
Thanks Martin, for your reply.
