Write a method that calculates and prints both the maximum humidity and maximum temperature values from the abq_weather_cleaned.csv data set. You should write your method in the dataVisualization class we have been working on in lecture. Your method should use all of the variables that are already part of this program. In particular, you will need to use the data array variable. Your method should return nothing and take no input parameters; it's signature should be void max (). Your print outs should look like this: The max humidity is: 58 The max temperature is: 70
The code given below represents a saveTransaction() method which is used to save data to a database from the Java program. Given the classes in the image as well as an image of the screen which will call the function, modify the given code so that it loops through the items again, this time as it loops through you are to insert the data into the salesdetails table, note that the SalesNumber from the AUTO-INCREMENT field from above is to be inserted here with each record being placed into the salesdetails table. Finally, as you loop through the items the product table must be update because as products are sold the onhand field in the products table must be updated. When multiple tables are to be updated with related data, you should wrap it into a DMBS transaction. The schema for the database is also depicted. public class PosDAO { private Connection connection; public PosDAO(Connection connection) { this.connection = connection; } public void…

Consider the following equation for the sum of a finite arithmetic series: S, = n(a, ta where n is the number of elements in the series, a is the first element of the series, and a, is the last element of the series. Write a method that returns the sum of the elements stored in the array in 8 above. The array must be passed to the method as an argument. Your solution should implement the equation for the sum S.
In ArrayUtility class, create a public static method equals that receives two arrays of int's and returns true if they have the same length and equal corresponding elements. In ArrayUtilityTest class, create a public static method equalsTest that prints the results for the following 6 cases: two empty arrays, one empty and one singleton, two singleton with the same element, two singleton with different elements, two arrays with two identical elements, two arrays with two different elements. Call only this class in the main method and check the results. In ArrayUtility and ArrayUtilityTest, design, implement and test a method named isSorted that checks if an array of int-s is already sorted, i.e. all the elements are in increasing order. In ArrayUtility and ArrayUtilityTest, design, implement and test a method named generateIntArray that generates a random array with the provided length having elements randomly generated between a minimum and maximum value, including those values create…
Create a Golf Game. Allow for two players. Prompt for the player names. Each player plays 18 holes. Use an array or List for each player to hold their number of swings for each hole. Logical methods should be implemented for different tasks (broken out below). It is up to you to determine the parameters and return types of each method as appropriate. Method 1 - For each hole, the player has a number of swings. Determine the player's swings by generating a random number between 1 and 4. Store each players number of swings in the array/list. Method 2 - After completing the 18 holes, add up the number of swings for each hole for each player. The player with the fewest number of swings is the winner. Method 3 - Save the game data into a CSV file in the main project (root) directory. Name the file "Golf_Game_Player1_Player2.csv" using the player's names. The information in the file should look like this: playername, scoreforhole1, scoreforhole2, scoreforhole3, etc... Method 4 - In the…
True or False? Arrays cannot be passed as parameters, but must be used only in the main method.
In Chapter 7, you modified the GreenvilleRevenue program to include a number of methods. Now, using your code from Chapter 7 Case Study 1, modify your program so every data entry statement uses a TryParse()method to ensure that each piece of data is the correct type. Any invalid user entries should generate an appropriate message that contains the word Invalid, and the user should be required to reenter the data. An example: Enter number of contestants last year >> 1 Enter number of contestants this year >> 2 Last year's competition had 1 contestants, and this year's has 2 contestants Revenue expected this year is $50.00 The competition is bigger than ever! Enter contestant name >> Matt Talent codes are: S Singing D Dancing M Musical instrument O Other Enter talent code >> Sarah Invalid format - entry must be a single character That is not a valid code Enter talent code >> R That is not a valid code Enter talent code >> J That is not a valid code…
Overloading a method is to provide more than one method with the same name but with different signatures to distinguish them. True O False
Load your bag with some initial values, but do not fill it. Your client code should give the user the option to: display the contents of the bag using the class method “toVector” add values to the bag remove values from the bag sort the bag search for a value using their choice of either the iterative search or the recursive search - both need to be tested Allow the user to keep doing these things until they are done. Do not automatically sort the bag if the user chooses to search. Your program should give the user a message telling them they must first sort the bag before they can search.You decide what the user interface will be. Make it clear and easy to use. It can be very basic; nothing fancy. A menu driven program works well. Each value in your array should be unique - no value will appear in the array multiple times. Your array elements can be any data type – use a template class put in place in the code provided. You can write your client code to process a bag holding any…

Question 1 Change the code of the setTemps method to ensure that: - hour: must be in the interval 0 >> time1.setTime (25,10,63) >>> time1 1: 11: 3 Call this method in _init_ also to correct the values if they are not correct. Add the following methods to the Time class: isBefore (t2) returns True if the time represented by self is before the time of t2, otherwise it returns False. duration (t2) returns a new Time object with the number of hours, minutes, and seconds between self and t2. Test your methods in the interpreter or in the main program >> t1 = Time(12,4,0) >>> t2 = Time(10,2,1) >>> t1.before(t2) >>>t2.before(12,45,2) >>> t1.before(t2) True False >>> t1.duration(t2) >>> t2.before(t1) 0:41:2
What type of information does the following method return? public static void methodRankPoints(double points) int double nothing object Which statement is correct? The while loop repeats a set of code while a condition is not met. The number of iterations required of a while loop is always known before the while loop begins. The while loop repeats a set of code while a condition is met. The while loop does not require code to be added to manage iteration during each loop. Which of the following statements is true with regard to java exceptions? A try block can be followed by multiple catch blocks. A program automatically terminates immediately after a catch block is executed. Only one try/catch block is allowed in a single method. A try-catch is required in all methods.
