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.
