Question

The program first reads integer towncount from input, representing the number of pairs of inputs to be read. Each pair has a string and a character, representing the town's name and rating, respectively. One town object is created for each pair and added to ArrayList townlist. If a town object's rating is equal to 'a', call the town object's print() method. What is the purpose of the towncount variable in the program?

1) To store the number of towns
2) To store the number of pairs of inputs
3) To store the rating of a town
4) To store the name of a town

Answer 1

The towncount variable is used to store the number of pairs of inputs, where each pair includes a town's name and rating, in the program.

Step-by-step explanation:

The towncount variable in the program serves a specific purpose. It is used to store the number of pairs of inputs that the program will read. Each pair consists of a string and a character; the string represents the name of the town, and the character represents the rating of the town. The program will create town objects for each of these pairs and add them to an ArrayList named townlist. Whenever a town object has a rating equal to 'a', the program will invoke that town object's print() method to display the details of the town. Therefore, the correct answer to the question about the purpose of the towncount variable is option 2: To store the number of pairs of inputs.
