- 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…Inside this module, import random and blackout_utils, and define the following global variable, which you should use whenever appropriate: OPERATIONS = ['^', 'x', '/', '+', '-']For full marks, all the following functions must be part of this module: calculate(tokens): Takes one list of tokens as input corresponding to a mathematical equation. The function will evaluate both sides of the equality and return a list of three tokens: the result of the left-hand side (integer), the equals sign (string), and the result of the right-hand side (integer). The equation may contain any of the operations in the OPERATIONS list, as well as opening and closing parentheses. Your function should evaluate both sides of the equation while respecting order of operations (that is, parentheses, followed by exponentiation, then multiplication and division, and then addition and subtraction). Equations may have multiple sets of parentheses and nested parentheses. The contents of the inner-most nested…This is what i have current_price = int(input())last_months_price = int(input()) print(f"This house is ${current_price}. The change is ${current_price / 20000000 }","since last month.")print(f"The estimated monthly mortgage is ${(current_price * 0.051) / 12}.") but i cant seem to get hte current price down to -10000 like it says
- Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print:7 9 11 10 10 11 9 7 Hint: Use two for loops. Second loop starts with i = NUM_VALS - 1. Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int courseGrades[4]). Also note: If the submitted code tries to access an invalid array element, such as courseGrades[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message. #include <iostream>using namespace std; int main() { const int NUM_VALS = 4; int courseGrades[NUM_VALS]; int i; for (i = 0; i < NUM_VALS; ++i) { cin >> courseGrades[i]; } /* Your solution goes…File names: color_square.py, chessboard.py, test_squares.py Positions on a chess board are identified by a letter and a number. The letter identifies the column; the number identifies the row. See the image below. You will provide the functions that allow us to determine: if a chessboard square is either black or white, given its coordinates. If the row/column is valid or not for the standard chessboard For example, if we pass in “d” for the column and 4 for the row, your function that determines color should return the string: “BLACK”. If we pass in "k" for the column to your function that validates columns, that function should return the boolean False. Requirements: Your function for validating the column should be able to accept upper or lowercase strings as parameters. Your functions for validating the row should be able to accept integers or strings as parameters. Your function that determines black-or-white may assume that the input has been validated prior to us calling…The weather generator methods you will be writing for this assignment will: predict future precipitation pattern for one month: oneMonthGenerator find the number of wet or dry days in a given month’s forecast: numberOfWetDryDays find the longest wet or dry spell in a given month’s forecast: lengthOfLongestWetDrySpell
