Answer
Java uses dynamic method dispatch to call the overridden method.
In Java, method calls on objects are resolved at runtime using dynamic method dispatch. This means that the JVM determines the method to invoke based on the object's runtime type, not the reference type. For instance, if a 'Product' reference points to a 'Book' object and calls 'getDescription()', the 'Book's implementation is used even though the reference is of type 'Product'.
