Question

Identify the association between MyBrowser and HBox: class MyBrowser extends Region { private HBox toolBar;// additional code goes here } A) No association B) HAS-A C) IS-A D) OWNS-A

Answer 1

The association between MyBrowser and HBox in the provided code is a HAS-A relationship, where MyBrowser contains an instance of HBox.

Step-by-step explanation:

The association between MyBrowser and HBox in the given Java code snippet is a HAS-A relationship. This is evident from the instance variable declaration within the MyBrowser class. The private HBox toolBar indicates that each instance of MyBrowser contains an HBox, meaning it 'has' an HBox as part of its state.

Because HBox is not extended by MyBrowser, the relationship is not an IS-A relationship (which would have been represented by inheritance). Similarly, OWNS-A is not a standard term used in object-oriented programming to describe associations between classes, so that can also be discarded.
