What is the difference between constructor overloading and initializer in programming?
Constructor overloading allows a class to have multiple constructors with different parameters, while an initializer is a block of code that initializes an object.
Can you give me an example of constructor overloading?
Sure! In Java, you might have a class Book
with two constructors: one that takes the title and author, and another that takes just the title.
And what about initializers? How do they work?
Initializers are used to set up default values for instance variables. For example, you can use an initializer block to set default values for attributes when an object is created.
Are there any advantages to using one over the other?
Yes, constructor overloading provides flexibility in object creation, while initializers can simplify code by centralizing default value assignments.
