Question 1

Explain the use of the NOT operator.

Accepted Answer

You use the NOT operator, which is written as the exclamation point ( ! ), to negate the result of any Boolean expression. Any expression that evaluates as True becomes False when preceded by the NOT operator; and accordingly, any False expression preceded by the NOT operator becomes True.

Question 2

Why would a programmer need to use a range check? Give an example.

Accepted Answer

A range check is a series of statements that determine within which of a set of ranges a value falls. Consider a situation in which salespeople can receive one of three possible commission rates based on their sales.

A) True 
 B)False

Question 7

An alternative to using a Boolean expression, such as quizScore == 10, is to store the Boolean expression's value in a Boolean variable. How could you express this in Java?

Accepted Answer

For example, if isPerfectScore is a Bool

Question 8

Write a nested if statement that will check if the variable qtySold is greater than the QTY_QUOTA constant. If true, evaluate a second expression that will check if the variable totalSales is greater than the constant SALES_QUOTA. If the second expression is also true, create an assignment statement that will assign the constant BONUSAMT to the variable bonus. After BONUSAMT is assigned, the if structure ends.

Accepted Answer

if(salesAmt > QUOTA

System.out.println("Your totalPay amount is " + totalPay);
Why is the above code incorrect? What would be required to make the code execute correctly?

Accepted Answer

When you place a block within an if stat
