When you use the super keyword in constructor chaining, there are a few challenges you might face:
Order of Initialization: The order in which things get set up is really important. If you don’t set up the parent class (called the superclass) correctly first, it can leave some parts of the child class (called the subclass) unready to use. For example, in Java, you must put super() at the very top of the constructor.
Issues with Multiple Inheritance: In some programming languages like Java, you can't have a class that inherits from more than one parent. This means if you try to use super from different parent classes, it will cause an error when you try to run your code. This can make it harder to do things in a flexible way.
Constructor Arguments: The number or type of arguments you give to the super call needs to match exactly. If they don't, it can create problems. A study done in 2021 found that about 30% of students felt confused about how to pass arguments to superclass constructors.
More Complexity: Keeping track of constructor chaining can make your code more complicated. This can make it harder for other people (or even you later on) to read and maintain the code. Developer feedback suggests this can affect maintainability and readability by up to 40%.
