Chapter 2.1, Problem 6SC
Explanation of Solution
Comments in Java:
A comment is used to document the program by using the line or paragraph comment for better understanding of the program. The compiler treats the comment as a white space.
Comment ignored by the compiler or not:
“Yes”, the comments are ignored by the compiler.
- If the compiler encounters a line comment (//), then it ignores the words up to the end of the line.
- If the compiler encounters a paragraph comment (/ * .. */), then it ignores the statement between the symbol /* and */...

Requirements: Evaluate the following expression for any value of the variable x, and save the
result in a variable of the type double. You must use the abs(), pow(), and sqrt() methods of the
Math class to perform the calculation. You may use a single assignment statement with a
somewhat large expression, or you may break the expression into multiple assignment statements.
The latter may be easier to debug if you are not getting the correct result.
5x +3} ( √8x* — 6x²³ + 4x² + |20x+1)
(9x³+7x² +5x+3)
Next, determine the number of digits to the left and to the right of the decimal point in the result.
[Hint: You can convert the double variable into a String variable using the static method
Double.toString(result). Then, on this String variable use the indexOf() method from the String
class to find the position of the decimal point (".") and use the length() method to find the length.
Knowing the location of the decimal point and the length of the String, you…
Design the worst calculator ever: an application that accepts two numbers from the user and, when a button is pushed, performs a single operation and displays the results.
You may choose: Multiplication, Division, Subtraction, square root, or raising the first number to the exponent of the second number. Don't use addition as we already did that in class.
The result must be displayed to the user only when an appropriately labeled button is pushed.
b = 0;
while (b < 100) ---------------(A)
b += 1; ------------------(B)

- The Westfield Carpet Company has asked you to write an application that calculates theprice of carpeting for rectangular rooms. To calculate the price, you multiply the area of thefloor (width times length) by the price per square foot of carpet. For example, the area offloor that is 12 feet long and 10 feet wide is 120 square feet. To cover that floor with carpetthat costs $8 per square foot would cost $960. (12 3 10 3 8 5 960.)First, you should create a class named RoomDimension that has two fields: one for the lengthof the room and one for the width. The RoomDimension class should have a method thatreturns the area of the room. (The area of the room is the room’s length multiplied by theroom’s width.)Next you should create a RoomCarpet class that has a RoomDimension object as a field. Itshould also have a field for the cost of the carpet per square foot. The RoomCarpet classshould have a method that returns the total cost of the carpet.Figure 8-21 is a UML diagram that shows…arrow_forwardexplain whyarrow_forwardWhat is the final value of y? int x = 4; 6; int y if (x < 10) { if (y < 5) { y = y + 1; } } else { } y = 7; } else { y = y + 10;arrow_forward
