Chapter 7, Problem 4E
Read through the LogAnalyzer class and identify all the places where the hourCounts variable is used. At this stage, do not worry about what all the uses mean, as they will be explained in the following sections. Note how often a pair of square brackets is used with the variable.

Need help with the following:
Adding comments to help explain the purpose of methods, classes, constructors, etc. to help improve understanding.
Implementing enhanced for loop (for each loop) to iterate over the numbers array in the calculateProduct method.
Creating a separate class for the UI and a separate class for the calculator logic.
Lastly, creating a constant instead of hard coding the number "5" in multiple places.
Thank you for any input/knowldge you can transfer to me, I appreciate it.

In the sections that follow, you will discover the definitions of the classes MonthCalender and DateTimerPicker.
In this assignment, you will need to add a new method to the Date class, which you
can find on D2L in the "Sample Code" section.
The new method should make a Date object's day, month, and year value change to
the next day. In other words, add one day to the object's current date. Do not use any
part of the built-in DateTime class, but you may want to use the DaysInMonth()
method from the Date class.
Examples:
• If the Date object stores the date 12/31/2021, then after calling your method
it should store the date 1/1/2022
• If the Date object stores the date 2/28/2022, then after calling your method it
should store the date 3/1/2022
As noted in the common instructions, you only need to turn in your new method, not
the entire Date class.

- How to Use/Re-Use a Variable Explain how many variables to set up in order to solve a problem in the lab class. Use an example to explain how the variables are changed.arrow_forwardComplete the following code. Attach the simulation too.arrow_forwardCreate a public class Connections with a single public constructor that accepts a String. The String contains, in CSV format, a list of cities and other cities that they are connected to. So, for example, the input: Champaign,Chicago,St. Louis Chicago,Detroit,Milwaukee St. Louis,Champaign,Cincinnati Means that Champaign is connected to Chicago and St. Louis, and that Chicago is connected to Detroit and Milwaukee, and so on. Essentially the CSV serializes a directed graph, where the first item on each line is a node and the other items represent other nodes that it is connected to. This is one way of serializing a directed, unweighted graph. If the String passed to the constructor is null, throw an IllegalArgumentException. Make sure to trimall the Strings that you extract from the CSV. Your class should parse this String and provide a single instance method isConnected. isConnected accepts two Strings and returns true if the first city is connected to the second based on the graph…arrow_forward
- Copy your previous class definition for RectangularSolid from the previous problem, including both methods. Provide mutators (setters) and accessors (getters) for each of the three parameters. Use the naming convention for these methods that is demonstrated in your textbook (i.e. do not use the property function or decorators). These methods should allow a program using your code to modify the parameter values after creation and to read individual parameter values.arrow_forwardIn this second exercise, we are going to look at the iIn this exercise, you are going to complete the Rectangle class. You need to complete the class so that you can print and compare two rectangles. Once complete, use the RectangleTester to test the results. In the tester class, you are given 3 rectangles that you should print and compare. Sample results are provided below. Sample output A rectangle with a width of 5 and a height of 4 A rectangle with a width of 5 and a height of 4 A rectangle with a width of 10 and a height of 4 true false public class RectangleTester{public static void main(String[] args){Rectangle rect1 = new Rectangle(5, 4);Rectangle rect2 = new Rectangle(5, 4);Rectangle rect3 = new Rectangle(10, 4);// Print all three rectangles// Print one true statement comparing rectangles// Print one false statment comparing rectangles}} public class Rectangle{ private int width;private int height;public Rectangle(int width, int height) {}}arrow_forwardComplete MyProgram such that you can test all conditions In the Theater constructor you need to instantiate each seat object based upon the information passed to the constructor, making sure they are available. In the reassign method, make sure the from and to seat assignments are within range and return false if not. There is test cases included with this exercise, so when you submit your screenshot, it needs to show the test cases passed.arrow_forward

What am I?" And the only way to continue to the next room is to type, "A temper," or "temper." And for another room, a help command. For example, the user will type, "help," and they will be told where to go next so they can each the winning room.arrow_forwardThe next sections will provide you with the definitions of the classes MonthCalender and DateTimerPicker respectively.arrow_forward

Thank youarrow_forwardFinish the TestPlane class that contains a main method that instantiates at least two Planes. Add instructions to instantiate your favorite plane and invoke each of the methods with a variety of parameter values to test each option within each method. To be able to test the functionality of each phase, you will add instructions to the main method in each phase.arrow_forwardWith the addition of electric cars, we have a need to create a subclass of our Car class. In this exercise, we are going to create the Electric Car subclass so that we can override the miles per gallon calculation since electric cars don’t use gallons of gas. The Car class is complete, but you need to complete the ElectricCar class as outlined in the starter code with comments. Once complete, use the CarTester to create both a Car and ElectricCar object and test these per the instructions in the CarTester class. public class CarTester{public static void main(String[] args){// Create a Car object// Print out the model// Print out the MPG// Print the object// Create an ElectricCar object// Print out the model// Print out the MPG// Print the object}} public class Car { //This code is completeprivate String model;private String mpg; public Car(String model, String mpg){this.model = model;this.mpg = mpg;} public String getModel(){return model;} public String getMPG(){return mpg;} public…arrow_forward
