An object is an instance of a 0 A. program 0 B. class 0 C. method D. data 5 Suppose you wish to provide an accessor method for a boolean property finished, what signature of the method should be? 6 7 8 Analyze the following code and choose the best answer: public class Foo { } private int x; public static void main(String[] args) { Foo foo new Foo(); System.out.println(foo.x); A. public void getFinished() B. public boolean getFinished() C. public boolean isFinished() D. public void isFinished() To declare a constant MAX LENGTH as a member of the class, you write. A. final static MAX_LENGTH = 99.98; B. final static float MAX LENGTH = 99.98; C. static double MAX_LENGTH = 99.98; D. final double MAX_LENGTH = 99.98; E. final static double MAX_LENGTH = 99.98; A. Since x is private, it cannot be accessed from an object foo. B. Since x is defined in the class Foo, it can be accessed by any method inside the class without using an object. You can write the code to access x without creating an object such as foo in this code. C. Since x is an instance variable, it cannot be directly used inside a main method. However, it can be accessed through an object such as foo in this code. D. You cannot create a self-referenced object; that is, foo is created inside the class Foo. Which of the following statement is most accurate? A. A reference variable is an object. B. A reference variable refers to an object. C. An object may contain other objects. D. An object may contain the references of other objects. To prevent a class from being instantiated.. A. don't use any modifiers on the constructor B. use the public modifier on the constructor C. use the private modifier on the constructor D. use the static modifier on the constructor
