# Expenses Project

Welcome to the cifojava2021-javase-2 wiki Expenses PROJECT!

				break;

				LoginController.validateUser();

					lenguage = russian;

			} else {

				System.out.println(

						"\nPlease, you have to write \"create\", \"login\" or \"quit\". Try another time ...\n");

			}

		}

		reader.close();

	}`

## Expenses Project v0.3

We go deep on login just doing a nice draft of login and the need of a new package: utils.

Managment

* /expensesProject0.4/src/menu/spanishMenu.java

model

* /expensesProject0.4/src/model/Language.java

* /expensesProject0.4/src/model/User.java

utils

* /expensesProject0.4/src/utils/RandomUtils.java

* /expensesProject0.4/src/utils/**UsersUtils.java**

* /expensesProject0.4/src/utils/UserUtils.java

`public static ArrayList validateUser(Scanner reader, ArrayList users) {

		

		int count = 1;

		String userConsole;

		String passwordConsole;

		System.out.println("\nWelcome Login to Expenses");

		do {

			System.out.println("\nEnter Username : ");

			userConsole = reader.next();

			System.out.println("Enter Password : ");

			passwordConsole = reader.next();

			if (validateUserAndPassword(userConsole, passwordConsole, users)) {

				System.out.println("Access Granted! Welcome!");

				return users;

			} else if (validateUser(userConsole, users)) {

				System.out.println("Invalid Password!");

			} else if (validatePassword(passwordConsole, users)) {

				System.out.println("Invalid Username!");

			} else {

				System.out.println("Invalid Username & Password!");

			}

			System.out.println("Total attempts: " + count + "/3");

			count++;

			if (count == 4)

				// to-do it is just a println

				//we need to set field isBlocked to false

				System.out.println("User blocked!");

		} while (count < 4);

		return users;

	}`

## Expenses Project v0.5

## Expenses Project v0.6

## Expenses Project v0.7

We create a HashMap in **languagesController**

`public static HashMap initLanguages()`

## Expenses Project v0.8

Improvements in Management class: we add **Date** to Expenses.

**createExpense**

`public static void createExpense(Scanner reader, User userValidated)`

`SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");`

`Date todayDate = new Date();`

	    

`System.out.print("Today date is ");`

`System.out.println(dateFormat.format(todayDate));`

			

`userValidated.add(new Expense(expenseName, valueExpense, todayDate));`

**updateExpense**

`public static void updateExpense(Scanner reader, User userValidated)`

				

System.out.print("Expense value: " + expense.getValue());

System.out.print(". Do you want to update expense value? (Y/N) ");

String updateValueAnswer = reader.next();

				

	if (updateValueAnswer.equalsIgnoreCase("Y")) {

		System.out.println("Enter expense value: ");

		double valueExpense = reader.nextDouble();

		expense.setValue(valueExpense);

	}

				

System.out.print("Expense date: " + expense.getDate());

System.out.print(". Do you want to update expense date? (Y/N) ");

String updateDateAnswer = reader.next();

				

	if (updateDateAnswer.equalsIgnoreCase("Y")) {

		System.out.println("Enter expense date (dd/MM/yyyy): ");

		String dateExpense = reader.next();

					

		Date dateToUpdate = expense.getDate();;

					try {

						dateToUpdate = new SimpleDateFormat("dd/MM/yyyy").parse(dateExpense);

					} catch (ParseException e) {

						System.out.print("Not updated! Invalid format!");

						e.printStackTrace();

					} 

		expense.setDate(dateToUpdate);

				}

					

				userValidated.update(count , expense);

				

				break;

And we create all languages classes with all the messages in a HashMap

## Expenses Project v0.9

Add the language package and **refactor** to:

* correct some variables names

* relocate some methods

* define future improvements

* close definition of v1.0

* arrange comments

* find some bugs
