Exam 3: Decision Structures

What will be the value of bonus after the following code is executed? Int bonus, sales = 10000; If (sales < 5000) Bonus = 200; Else if (sales < 7500) Bonus = 500; Else if (sales < 10000) Bonus = 750; Else if (sales < 20000) Bonus = 1000; Else Bonus = 1250;

In most editors, you are indenting by one level each time that you press this key:

Which of the following correctly tests the char variable chr to determine whether it is NOT equal to the character B?

This type of operator determines whether a specific relationship exists between two values:

What would be the value of discountRate after the following statements are executed? Double discountRate = 0.0; Int purchase = 1250; Char cust = 'N'; If (purchase > 1000) If (cust == 'Y') DiscountRate = .05; Else DiscountRate = .04; Else if (purchase > 750) If (cust == 'Y') DiscountRate = .04; Else DiscountRate = .03; Else DiscountRate = 0;

In Java, when a character is stored in memory, it is actually stored as a(n):

A local variable's scope always ends at the closing brace of the block of code in which it is declared.

What will be the value of ans after the following code has been executed? Int x = 90, y = 55, ans = 10; If ( x == y); Ans *= 2;

When testing for character values, the switch statement does not test for the case of the character.

What is the value of ans after the following code has been executed? Int x = 40; Int y = 40; Int ans = 0; If (x = y) Ans = x + 10;

Which of the following will format 12.78 to display as 12.8%?

If str1 and str2 are both Strings, which of the following will correctly test to determine whether str1 is less than str2? (1) (str1 < str2) (2) (str1.equals(str2) < 0) (3) (str1.compareTo(str2) < 0)

What will be the values of ans, x, and y after the following statements are executed? Int ans = 35, x = 50, y =50; If ( x >= y) { Ans = x + 10; X -=y; } Else { Ans = y + 10; Y += x; }

What would be the value of discountRate after the following statements are executed? Double discountRate = 0.0; Int purchase = 1250; If (purchase > 1000) DiscountRate = .05; If (purchase > 750) DiscountRate = .03; If (purchase > 500) DiscountRate = .01; Else DiscountRate = 0;

What would be the value of bonus after the following statements are executed? Int bonus, sales = 85000; Char dept = 'S'; If (sales > 100000) If (dept == 'R') Bonus = 2000; Else Bonus = 1500; Else if (sales > 75000) If (dept == 'R') Bonus = 1250; Else Bonus = 1000; Else Bonus = 0;

A block of code is enclosed in a set of:

What will be the values of ans, x, and y after the following statements are executed? Int ans = 0, x = 15, y =25; If ( x >= y) { Ans = x + 10; X -=y; } Else { Ans = y + 10; Y += x; }

Which of the following is the correct boolean expression to test for: int x being a value less than or equal to 500 or greater than 650, and int y not equal to 1000?

What would be the value of discountRate after the following statements are executed? Double discountRate; Char custType = 'B'; Switch (custType) { Case 'A': DiscountRate = .08; Break; Case 'B': DiscountRate = .06; Case 'C': DiscountRate = .04; Default: DiscountRate = 0.0; }

The System.out.printf method formats a string and displays it in the console window.
