2. 16. Methods that you reference with individual objec a. private b. public 1. d. no 17. Variables that are shared by every instantiation of a class are. a. class variables private variables c. public variables d. illegal 18. The keyword final used with a variable declaration indicates, c. a symbolic constant a. the end of the program b. it is in a static method d. that no more variables will be declared in the program 19. Which of the following statements determines the square root of a number and assigns it to the variable s? 20. Which of the following expressions correctly returns an integer that represents the month of a LocalDate s sqrt (number); C. b. s = Math.sqrt (number); number = sqrt(s); d. number = Math.sqrt(s); object named hireDate? a. getMonth (hireDate) b. getMonthValue (hireDate) c. hireDate.getMonthValue () d. hireDate.setMonthValue() Programming Exercises a. Create a class named Sandwich. Data fields include a String for the main ingredient (such as tuna), a String for bread type (such as wheat), and a double for price (such as 4.99). Include methods to get and set values for each of these fields. Save the class as Sandwich.java. b. Create an application named Test Sandwich that prompts the user for data, instantiates one Sandwich object, and displays its values. Save the application as TestSandwich.java. a. Create a class named Lease with fields that hold an apartment tenant's name, apartment number, monthly rent amount, and term of the lease in months. Include a default constructor that initializes the name to XXX, the apartment number to 0, the rent to 1000, and the term to 12. Also include methods to get and set each of the fields. Include a nonstatic method named addPet Fee () that adds $10 to the monthly rent value and calls a static method named explainPet Policy () that explains the pet fee. Save the class as Lease.java. alsb sdt b. Create a class named TestLease whose main () method declares four Lease objects named leasel, lease2, lease3, and lease4. Create a getData() method that prompts a user for values for each field for a Lease, and return a newly constructed Lease object to the main () method, where it is assigned to one of main () 's first three Lease objects. Do not prompt the user for values for the fourth Lease object, but let it hold the default values. After the four Lease objects have been assigned values, pass the leasel object to a showValues () method that displays the data. Then call the addPet Fee () method with the leasel object, and confirm that the fee explanation statement is displayed. Next, call the showValues () method for the leasel object again and confirm that the pet fee has been added to the rent. Finally, call the showValues () method with each of the other three objects. Confirm that three hold the values you supplied as input and one holds the constructor default values. Save the application as TestLease.java. 4.
