What are the benefits of having a destructor for a class?
In Java programming (Lesson: Objects, Classes, and Constructors)
Every class has a constructor and if we do not explicitly write a constructor for a class, the java compiler builds a default constructor for that class.
False or True
Please provide an explanation for the answer. Thank you!
Object adapters and class adapters each provide a unique function. These concepts are also significant due to the significance that you attach to them.
