Does parent class contain subclass in java?
No, in Java, parent classes do not directly contain subclasses. Subclasses possess the characteristics of the parent class by inheriting its methods and properties. Inheritance, polymorphism, and overriding are key elements of the relationship between parent and child classes.
Does a parent class in Java contain subclasses?
Answer: No
In Java, a parent class does not directly contain a child class. Instead, the subclass inherits the methods and properties of the parent class, and therefore has the characteristics of the parent class.
Detailed explanation:
Java adopts the object-oriented programming paradigm, in which the relationship between parent classes and subclasses is as follows:
- Inheritance: The subclass inherits methods and properties from the parent class, but the subclass itself does not contain the code or data of the parent class.
- Polymorphism: A parent class can reference objects of any of its subclasses, allowing different subclasses to be treated as objects of the same type.
- Overriding: Subclasses can override methods in the parent class to provide their own implementation of the method.
Therefore, in Java, the parent class does not directly contain the subclass, but is associated with the subclass through inheritance and polymorphism. The parent class only defines the interface that the subclass must implement, and the subclass provides the actual implementation.
