Solution
All the statements are true:
-
To override a method, the method must be defined in the subclass using the same signature and compatible return type as in its superclass. This is true because overriding in Java requires the method in the child class to have the same name, return type, and parameters as the method in the parent class.
-
Overloading a method is to provide more than one method with the same name but with different signatures to distinguish them. This is true because method overloading in Java allows a class to have more than one method with the same name, but with different parameters.
-
It is a compile error if two methods differ only in return type in the same class. This is true because in Java, two methods within the same class cannot have the same name and parameters but different return types.
-
A private method cannot be overridden. If a method defined in a subclass is private in its superclass, the two methods are completely unrelated. This is true because private methods are not visible to subclasses and therefore cannot be overridden.
-
A static method cannot be overridden. If a static method defined in the superclass is redefined in a subclass, the method defined in the superclass is hidden. This is true because static methods belong to the class, not the instance, and therefore cannot be overridden in the traditional sense. Instead, the static method in the subclass hides the one in the superclass.
