1Z0-811 Java Basics and Syntax Practice Question

A parent class has a static method display() and an instance method show(). A child class attempts to override both. What is the outcome?

⚠ Common exam trap

Test-takers frequently confuse method hiding with overriding, assuming static methods follow the same polymorphic rules as instance methods, leading them to incorrectly select option A or C.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Only show() can be overridden

In Java, static methods belong to the class, not instances, so they cannot be overridden—they can only be hidden. Instance methods, however, can be overridden to provide polymorphic behavior. Therefore, only the instance method show() can be overridden; display() is hidden, not overridden.
