- Assignment 5A: Multiple Frequencies. In the last assignment, we calculated the frequency of a coin flip. This required us to have two separate variables, which we used to record the number of heads and tails. Now that we know about arrays, we can track the frequency of all numbers in a randomly generated sequence. For this program, you will ask the user to provide a range of values (from 1 to that number, inclusive) and how long of a number sequence you want to generate using that number range. You will then generate and save the sequence in an array. After that, you will count the number of times each number occurs in the sequence, and print the frequency of each number. Hints: You can use multiple arrays for this assignment. One array should hold the number sequence, and another could keep track of the frequencies of each number. Sample Output #1: What's the highest number you want to generate?: 5 How Long of a number sequence do you want to generate?: 10 Okay, we'll generate 10…This program asks the user to enter 4 names for a team,storing them in an array of Strings.Then the program changes the array, replacing the firstteam member with Craig. Then this modified list ofnames is printed on the screen. You can see sampleoutput at the end of this file. 1) inputTeam: Input and return an array of Strings,with the specified number of elements (one int parameter).2) substitute: Has 3 parameters: an array of Strings,and two String names. Changes the array by replacing theelement containing the nameToRemove with the nameToAdd.3) outputArray: Has 1 parameter: an array of Strings.Outputs all the array elements, separated by spaces. import java.util.Scanner; class Main{ public static void main(String[] args) { String[] team; String nameToRemove, nameToAdd; System.out.println("Please enter 4 names for this team:"); team = inputTeam(4); nameToRemove = team[0]; nameToAdd = "Craig"; System.out.println("Sorry, we need to replace " + nameToRemove…text file 80 1 2 3 100 100 100 1001 0 2 100 3 4 100 1002 2 0 4 4 100 5 1003 100 4 0 100 100 4 100100 3 4 100 0 3 3 3100 4 100 100 3 0 100 1100 100 5 4 3 100 0 2100 100 100 100 3 1 2 0 My code below.

- JAVA Write an application containing three parallel arrays that hold 10 elements each. The first array hold four-digit student ID numbers, the second array holds first names, and the third array holds the students’ grade point averages. Use dialog boxes to accept a student ID number and display the student’s first name and grade point average. If a match is not found, display an error message that includes the invalid ID number and allow the user to search for a new ID number.a. The mean of a list of numbers is its arithmetic average. The median of a list is its middle value when the values are placed in order. For example, if a list contains 1, 4, 7, 8, and 10, then the mean is 6 and the median is 7. Write an application that allows you to enter five integers and displays the values, their mean, and their median. Save the files as MeanMedian.java. b. Revise the MeanMedian class so that the user can enter any number of values up to 20. If the list has an even number of values, the median is the numeric average of the values in the two middle positions. Save the file as MeanMedian2.java.A file named history.txt contains unknown number of car records (maximum no. of records is 50). Each line in the file consists of car model (string), mileage (integer), and number of accidents (integer). Write a program that reads the data from the file into 3 parallel arrays. Your program should display the following: • Display the number of cars found. Display car information (car model and number of accidents) for all cars in file. • Display the average mileage of all cars Display the car model with the highest number of accidents.
- If you have downloaded the source code from this book’s companion Web site, you will find a file named USPopulation.txt in the Chapter 07 folder. The file contains the midyear population of the United States, in thousands, during the years 1950 through 1990. The first line in the file contains the population for 1950, the second line contains the population for 1951, and so forth.Write a program that reads the file’s contents into a list. The program should display the following data:• The average annual change in population during the time period• The year with the greatest increase in population during the time period• The year with the smallest increase in population during the time period(You can access the book’s companion Web site at www.pearsonglobaleditions.com/gaddis.)You develop a Python application for your company.A list named employees contains 200 employee names, the last five being company management. You need to slice the list to display all employees excludingmanagement.Which two code segments should you use? Each correct answer presents a complete solution. (Choose two.) Group of answer choices E. employees [0:-5] D. employees [0:-4] B. employees [:-5] A. employees [1:-4] C. employees [1:-5]Counting hashtags Write Python code to count the frequency of hashtags in a twitter feed. Your code assumes a twitter feed variable tweets exists, which is a list of strings containing tweets. Each element of this list is a single tweet, stored as a string. For example, tweets may look like: tweets = ["Happy #IlliniFriday!", "It is a pretty campus, isn't it, #illini?", "Diving into the last weekend of winter break like... #ILLINI #JoinTheFight", "Are you wearing your Orange and Blue today, #Illini Nation?"] Your code should produce a sorted list of tuples stored in hashtag_counts, where each tuple looks like (hashtag, count), hashtag is a string and count is an integer. The list should be sorted by count in descending order, and if there are hashtags with identical counts, these should be sorted alphabetically, in ascending order, by hashtag. From the above example, our unsorted hashtag_counts might look like: [('#illini', 2), ('#jointhefight', 1),…
- String[] countyNames = {"Kings", "Albany", "New York", "Orange", "Bronx", "Queens", "Richmond"}; Using the above statement, what will be the value of countyNames [0], countyNames [1], and countyNames [7]? What will be the value of countyNames [2].length (), and countyNames [3].length ()?Suppose a teacher has five students who have taken four tests. The teacher uses the following grading scales to assign a letter grade to a student, based on the average of his or her four test scores. Test Score Letter Grade 90-100 80-89 70-79 60-69 0-59 A B C D F Create an application that uses an array of strings to hold the five student names, an array of five strings to hold each student's letter grades, and five arrays of four single precision numbers to hold each student's set of test scores.Cargo Container Report. You will be producing a program which will allow the user to generate the container report on the following page in Container Number order or Ship Name order. The program will also the user to lookup the data for any given Container by number. The % cargo weight is the percentage of the cargo of the gross weight (cargo weight/gross weight), % total is the percentage of the cargo for that container of the total amount of cargo unloaded (cargo weight for the container / total cargo unloaded. Hint: you are expected to use methods for your calculations. The accompanying file has the data for the containers unloaded today. The data includes container number int ship name. String tare weight of the container (empty weight) int the gross weight (container plus the cargo). Int You will need to computer the cargo weight as the gross weight minus the tare weight. If you have issues reading the data with the String, you may remove the String. However, you will lose points.…
