1. Which of the following is NOT true about encapsulation? * Loosely called "information hiding" Separates the interface of an object from its implementation The interface consists of the outside view of an object The implementation of the behavior should be visible to other objects O None of the above 2. Which of the following statements is/are TRUE? To allow all classes, regardless of their package declaration, access an object's feature, it must be declared as default. java.util is an example of a user-defined package. I. I. I only Il only Both I and II Neither I nor || 3. Which of the following is wrong when encapsulating a class? * All instance attributes should be set to private Setting the constructor to private will not allow objects to be instantiated Methods are always public to allow other classes to call them If public and default both works as access O modifier for class, choose the more strict one (default) None of the above
