The super() keyword in Java is primarily used to call the constructor of the parent class. This is crucial because when a subclass is instantiated, it needs to also properly initialize the part of the object that is inherited from its parent class. Using super() allows you to invoke the parent class's constructor, ensuring that any setup or initialization defined there can be executed before additional initialization occurs in the subclass's constructor.

This mechanism is fundamental in object-oriented programming as it supports the idea of inheritance, where a subclass builds upon the foundation provided by its parent class. By calling the parent's constructor, you help maintain a coherent chain of initialization, which is especially important when the parent class has specific properties or methods that the subclass relies on.

In this context, the other options do not accurately represent the primary function of super(). While accessing private members, creating instances, or overriding methods relates to inheritance and class relationships, they do not pertain directly to what the super() keyword specifically achieves in the constructor context.
