Let's address the questions provided in the text.

Question: Assuming scnr already exists, which statement gets an input number into variable numCars?

Options:

1. scnr.nextInt(numCars);
2. numCars = scnr.nextInt;
3. numCars = scnr.nextInt();

Answer: The correct statement is the third one: numCars = scnr.nextInt();

Explanation:

1. scnr.nextInt(numCars); - This is incorrect because nextInt() does not take any arguments.
2. numCars = scnr.nextInt; - This is incorrect because nextInt is a method and should be called with parentheses ().
3. numCars = scnr.nextInt(); - This is correct because it properly calls the nextInt() method of the Scanner class and assigns the input value to numCars.

Question: Type a statement that gets an input value into variable numUsers. Assume scnr already exists and numUsers has been declared.

Answer: The correct statement is: numUsers = scnr.nextInt();

Explanation:

• scnr.nextInt() is the method used to read an integer input from the user.
• numUsers is assigned the value returned by scnr.nextInt().

For both questions, the correct way to get an input value into a variable using a Scanner object is by calling the nextInt() method and assigning its return value to the variable. The correct statements are:

• numCars = scnr.nextInt();
• numUsers = scnr.nextInt();
