abstract class in java with constructor

List Docs
  • Can we have private constructor in abstract class?

    It is also abstract, so while it cannot be instantiated, it can still be extended because Java adds an implicit public constructor to every class.
    In this case, the best practice is usually to declare a private constructor, that way, no one can subclass it or create an instance of it.

  • How to initialize abstract class Java?

    We cannot instantiate the abstract class in Java directly.
    Instead, we can subclass the abstract class.
    When we use an abstract class as a subclass, the abstract class method implementation becomes available to all of its parent classes.

  • Can an abstract class have a constructor in Java?

    Abstract classes can have constructors, but they cannot be instantiated directly.
    The constructors are used when a concrete subclass is created.
    There may be one or greater abstract methods in an abstract class, which signifies that those methods are not implemented by means of the class.

  • If you want your abstract class to appear to be instantiable, define a factory constructor.
