How does Java handle a method in a derived class that has the same signature as a private method in the base class?

It overrides the base class method
It overloads the base class method
It is considered a new method not related to the base class method
It triggers a compile-time error

The correct answer is: It overloads the base class method

Java handles methods with the same signature in a derived class as private methods in the base class by overloading the base class method. This means that the derived class will have a new method with the same name and same parameters, but it will have a different implementation from the private method in the base class. Option A is incorrect because if the method in the base class was public, then the derived class would override it. Option C is incorrect because even though the method has the same signature, it is still related to the method in the base class and can be accessed through inheritance. Option D is incorrect because it will not cause a compile-time error as it is allowed in Java to overload private methods from the base class in a derived class.
