1. Based on the code below, answer these questions (identify line numbers for Java statements):

Which line(s) will be executed if the condition in line 3 is true?
Processing then will proceed to which line?

Which line(s) will be executed if the condition in line 3 is false?
Processing will then proceed to which line?

Line 10 will always be executed whether line _____ is true or false.

Lines 5-6 will only be executed when line ______ is ____________.
Line 9 will only be executed when line ______ is ____________.

 

1 double purchasesYTD = 200.0;

2 double discount = 0.0;

3 if(purchasesYTD>= 200.00)

4 {

5 System.out.printf("%nUse this promo code on your next purchase ME09X1.");

6 discount = .10;

7 }

8 else

9 System.out.printf("%nPlease check our daily specials.");

10 System.out.printf("%nYou qualify for a %.0f%% discount.", discount);

2. Re-code the IF/ELSE structure in lines 3-9 above so the else statement is now the if statement. HINT: The condition tested should be reversed.

3. Use printf() with format specifiers as needed. Code on this page the following:

a. Code an if statement that prints "I got the promotion!". The if condition tests the boolean variable promotion which is already declared.

b. Given a boolean variable called inactive,use the conditional operator (ternary operator) to assign ‘Y' to the variable closeAcct; otherwise, assign‘N'. Assume both variables are already declared.

c. Write an if-else statement that assigns 2 extra credit points for an 80% class attendance rate, 3 extra credit points for an 85% class attendance rate, and 5 extra credit points for anything 90% and above. Assume extraCreditand attendancearealready declared. Make sure you scope the code properly

d. Code a while loop that keeps printing "You are a DEDICATED student!" as long as the user enters an attendance rate of 90% or greater. Assume the loop-control variable, attendance, is already declared along with input for the Scanner class. The while loop requires a priming read for the loop-control variable prior to entering the loop.

e. There are 20 students. Code a while loop that processes extra credit points for student attendance. Use the if/else coded in 3c. Print "Sorry, you've not earned any extra credit for your attendance." or "Congratulations! You've earned 9extra credit points because of your good attendance." where the 9 is the actual number of points earned based on the if/else from 3c. Assume the input variable for the Scanner class, the attendanceand extraCreditvariables are already declared. Declare the loop-control variable.
