Hello, to my all readers, Hope you all are enjoying your daily learning. Among my daily updates, Today I have come up with new topic related to java technology.
Please find below my insights on today's technical concept, specifically??Java Inner and Sub Classes. I invite you to peruse this information, as it may offer valuable insights and benefits to your understanding of java classes techniques.
- An inner class is a class defined within another class. It exists within the scope of the enclosing class and has access to its members, including private members.
- Inner classes are commonly used to logically group classes together when one class should only be used by the other, or when the inner class is too closely associated with the outer class to make sense on its own.
- Inner classes can be of various types, such as static inner classes, non-static inner classes (also known as member classes), local inner classes, and anonymous inner classes.
Subclass (or Derived Class):
- A subclass is a class that inherits from another class, known as its superclass or base class. The subclass inherits the fields and methods of its superclass and can also have its own additional fields and methods.
- Subclasses are used in inheritance, a fundamental concept in object-oriented programming. Through inheritance, a subclass can reuse the code of its superclass and extend its functionality by adding new features or overriding existing methods.
- Subclasses can have their own subclasses, creating a hierarchy of classes with increasing levels of specialization.
Difference between Inner And Sub Classes-
- Inner classes are typically used for organization and encapsulation, often to hide implementation details or to provide a specific type that is closely associated with its enclosing class.
- Subclasses are used primarily for inheritance and code reuse, allowing classes to be extended and specialized while maintaining a hierarchical relationship.
- Inner classes exist within the scope of their enclosing class. They have access to all members of the enclosing class, including private members.
- Subclasses inherit from their superclass but exist independently of it. They can access public and protected members of their superclass but not private members unless accessor methods are provided.
- Inner classes do not involve inheritance. They are simply nested within another class for organizational purposes.
- Subclasses are created explicitly through the inheritance mechanism, where one class (the subclass) extends another class (the superclass) to inherit its properties and behavior.
Inner classes are about encapsulation and organization, while subclasses are about inheritance and specialization.
