These questions do not contain an array bag. They are supposed to be general answers to the topic.

The invariants of a class are written for the programmer. The invariants are statements about the instance variables (fields) of the class. The programmer who is writing a method can depend on the invariants being true at the beginning of the method, and he/she must make sure they are true when the method finishes. What are the invariants for each of the instance variables in the IntArrayBag class? (Answer in question 1 & question 2) What is the invariant for data? 7 A- B I I II! I!!! c > What is the invariant for manyltems? 7 A B I I iii E a cs C > In the add, addAll, and addMany methods, what happens when data.length is not large enough to support the addition of the items? 1 .
