Chapter 6, Problem 11E

Create a class Android whose objects have unique data. The class has the following attributes:

• tag—a static integer that begins at 1 and changes each time an instance is created
• name—a string that is unique for each instance of this class

Android has the following methods:

• Android—default constructor that sets the name to “Bob” concatenated with the value of tag. After setting the name, this constructor changes the value of tag by calling the private method changeTag.
• getName—returns the name portion of the invoking object.
• isPrime(n)—a private static method that returns true if n is prime—that is, if it is not divisible by any number from 2 to n − 1.
• changeTag—a private static method that replaces tag with the next prime number larger than the current value of a tag.
