In Java: The CSV (or comma-separated values) format is commonly used for tabular data. Each table row is a line, with columns separated by commas. Items may be enclosed in quotation marks, and they must be if they contain commas or quotation marks. Quotation marks inside quoted fields are doubled. Here is a line with four fields: 1729, San Francisco, "Hello, World", "He asked: ""Quo vadis?""" Implement a class CSVReader that reads a CSV file, and provide methods int numberOfRows() int numberOfFields(int row) String field(int row, int column)

In Python, grades_dict = {'Wally': [87,96,70], 'Eva': [100,87,90], 'Sam': [94,77,90], 'Katie': [100,81,82],                'Bob': [83, 65, 85]} Ask user to enter the names of the rows, i.e., indices. You can use: len(grades) to get the number of rows of the DataFrame. In addition, using the sort_index() method, ask user whether they wish to sort by rows or by columns and whether to sort in ascending or descending order (do not use any if-else statements)

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 ()?

A file USPopulation.txt contains the population of the US starting in year 1950 and then each subsequent record has the population for the following year. USPopulation.txtDownload USPopulation.txt Write a program that uses an array with the file that displays these in a menu and then produces the results. This is not an Object Oriented Program but should be a procedural program, calling methods to do the following: 1: Displays the year and the population during that year 2. The average population during that time period (Add up the populations of all records and divide by the number of years). 3. The year with the greatest increase in population - print the year and that population and that amount. To figure this out, compare the difference in population before of say year 1950 and 1951, store that difference somewhere. Compare 1951 with 1952, find that difference. Is that difference greater than the stored difference? If so, move that the the maximum place. 4.…

For any element in keysList with a value greater than 50, print the corresponding value in itemsList, followed by a comma (no spaces). Ex: If the input is: 32 105 101 35 10 20 30 40 the output is: 20,30, 1 #include 2 3 int main(void) { const int SIZE_LIST = 4; int keysList[SIZE_LIST]; int itemsList[SIZE_LIST]; int i; 4 6 7 8 scanf("%d", &keysList[0]); scanf ("%d", &keysList[1]); scanf("%d", &keysList[2]); scanf("%d", &keysList[3]); 10 11 12 13 scanf ("%d", &itemsList[0]); scanf ("%d", &itemsList[1]); scanf("%d", &itemsList[2]); scanf ("%d", &itemsList[3]); 14 15 16 17 18 19 /* Your code goes here */ 20 21 printf("\n"); 22 23 return 0; 24 }

the only data that should b epresented as numerical values are those that represent numbers. data that represent categories should never be presented as numerical values. TRUE or FALSE
