I am preapring for Java interview, I came across this question.
Q) when you declare a method as a abstract, can other non abstract methods can access it?
Ans)Yes,other non abstract methods can access a method that you declare as a abstract.

I think this anwer is wrong.

Q1)Please correct me if i am wrong?

Try...




And "access" is the wrong word -- as you technically can't access anything that doesn't exist -- maybe "allowed to call" is better.

Try to google Template pattern...

A subclass implements abstract methods. In order to access non abstract methods in an abstract class, you have to intiate it with a subclass. Thats way there is no problem.

I wish it is clear

Yesss.....Non-abstract method can call Non-abstract method

Reason :- Compiler ensures that we cannot create an object for an abstract class.
This means whenever we could call that non-abstract method, it would be called only from the class which extends the abstract class.
In that case , the class which would extend the abstract class has to implement the abstract method.
So it is possible to call it !!!
