JAVA PROGRAM
Chapter 7. PC #16. 2D Array Operations
Write a program that creates a two-dimensional array initialized with test data. Use any primitive data type that you wish. The program should have the following methods:
• getTotal. This method should accept a two-dimensional array as its argument and return the total of all the values in the array.
• getAverage. This method should accept a two-dimensional array as its argument and return the average of all the values in the array.
• getRowTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row.
• getColumnTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the…
Write a class with name Arrays . This class has an array which should be initialized by user.Write a method Sum that should sum even numbers in array and return sum. write a function with name numFind in this class with working logic as to find the mid number of an array. After finding this number calculate its factorial.Write function that should display sum and factorial.Don’t use divide operator
Question: Get a series of numbers from the user. Let the user determine how many numbers to enter. Set an upper and lower limit for the number that will be array size. If the user enters the number as outside that range, ask him to enter the number again, with an error message on the screen until the correct number is entered. Calculate the largest and smallest elements, sum and average of the array created with the numbers entered by the user, using functions. Print the results obtained on the screen. Also get another input from the user. Use a function to calculate how many characters this input has, how many characters are letters, how many characters are numbers and how many characters are other characters. Print the results on the screen.

- (Electrical eng.) Write a program that declares three one-dimensional arrays named volts, current, and resistance. Each array should be declared in main() and be capable of holding 10 double-precision numbers. The numbers to store in current are 10.62, 14.89, 13.21, 16.55, 18.62, 9.47, 6.58, 18.32, 12.15, and 3.98. The numbers to store in resistance are 4, 8.5, 6, 7.35, 9, 15.3, 3, 5.4, 2.9, and 4.8. Your program should pass these three arrays to a function named calc_volts(), which should calculate elements in the volts array as the product of the corresponding elements in the current and resistance arrays (for example ,volts[1]=current[1]resistance[1]). After calc_volts() has passed values to the volts array, the values in the array should be displayed from inside main().arrow_forward(Data processing) Write a program that uses an array declaration statement to initialize the following numbers in an array named slopes: 17.24, 25.63, 5.94, 33.92, 3.71, 32.84, 35.93, 18.24, and 6.92.

Include these statements in a program that displays the values in the array.arrow_forward
- The add() method resizes the array properly when items are added to the array. In the arraybag.py file define the add() method in the ArrayBag class by completing the following: Check array memory and increase it if necessary To test your program run the test() method in the testbag.py file. Your program's output should look like the following:arrow_forwardWeight Statistics Write a program that monitors monthly weight loss each of 12 months into an array of doubles. The program should calculate and display the total weight loss for the year, the average monthly weight loss, and the months with the highest and lowest amounts. Input Validation: Do not accept negative numbers for monthly weight loss.arrow_forwardUSE C++ PROGRAMMING LANGUAGE Write a program that simulates a lottery. The program should have an array of five integers named winningDigits, with a randomly generated number in the range of 0 through 9 for each element in the array. The program should ask the user to enter five digits and should store them in a second integer array named player. The program must compare the corresponding elements in the two arrays and count how many digits match. For example, the following shows the winningDigits array and the Player array with sample numbers stored in each. There are two matching digits, elements 2 and 4. WinningDigits 7 4 9 1 3 player 4 2 9 7 3 Once the user has entered a set of numbers, the program should display the winning digits and the player’s digits and tell how many digits matched.arrow_forward

Take note that there is no comma after the last element. The method's signature is as follows: public static String arrayToString(int[] array) Also write a test driver to test this method (you should test on empty array, one-element array, and n-element array). Notes: This is similar to the built-in function Arrays.toString(). You could study its source code.
