This functionality is orchestrated by the `ListSavingsCommand` class, which is initialized by the `Parser` class.

The relevance of these class attributes in `ListSavingsCommand` is detailed in the following table: + +| Class Attribute | Variable Type | Relevance | +|-----------------|---------------|---------------------------------------------------------------------------------| +| savings | SavingList | The `SavingList` object containing the list of savings to be displayed or filtered | +| filterCategory | String | The category to filter the savings by, if provided | + +When `BudgetBuddy` invokes the `execute()` method via `command.execute()`, the `ListSavingsCommand` object uses several methods from the `SavingList` class to perform its tasks: + +| Method | Return Type | Relevance | +|------------------|--------------------|-------------------------------------------------------------------| +| getSavings() | ArrayList | Retrieves the list of all savings from the `SavingList` | +| findTotalSavings() | void | Calculates the total amount of savings stored in `SavingList` | +| listSavings() | void | Prints the savings, filtered by `filterCategory`, to the CLI | +| calculateRemainingSavings() | double | Calculates the remaining amount after deducting total expenses | + +The Listing Savings feature follows these steps when a user inputs a command to list savings: +1. The user inputs `list savings [optional: filterCategory]`.

The `Parser` returns this `ListSavingsCommand` object to `BudgetBuddy`, which calls `ListSavingsCommand.execute()`. +3. `execute()` calls `SavingList.listSavings(filterCategory)`, where the `filterCategory` is applied if provided. +4. Within `listSavings()`, the `findTotalSavings()` method is called first to calculate the initial total savings amount. +5. The `listSavings()` method continues by iterating through each `Saving` and printing those that match the `filterCategory` criteria. +6. After listing, the method calculates and displays the remaining savings by calling `calculateRemainingSavings(initialAmount, totalExpenses)`, accounting for any expenses deducted. +7.

The `execute()` method calls `ExpenseList.listExpenses(filterCategory)`. +4.

The importance of these class attributes is as follows: + +| Class Attribute | Variable Type | Relevance | +|------------------|-------------------|-----------------------------------------------------------------------------------| +| currencyConverter| CurrencyConverter | The object responsible for currency conversion calculations | +| expenseList | ExpenseList | Contains the expenses whose currency will be converted | +| savingList | SavingList | Contains the savings whose currency will be converted | +| newCurrency | Currency | The new currency to which the amounts will be converted | + +When `BudgetBuddy` calls `command.execute()`, `ChangeCurrencyCommand` employs the following methods from `CurrencyConverter` to convert the currency of all financial records: + +| Method | Return Type | Relevance | +|--------------------|-------------|-----------------------------------------------------------------------------------| +| convertCurrency() | void | Converts the currency of each `Expense` and `Saving` object to `newCurrency` | + +Here's the step-by-step process when the user uses the Currency Converter feature: +1. The user inputs `change currency [newCurrencyCode]`. `Parser` processes this input and constructs a `ChangeCurrencyCommand` object with the necessary attributes. +2. The `ChangeCurrencyCommand` object is returned to `BudgetBuddy`, which calls `ChangeCurrencyCommand.execute()`. +3. `execute()` invokes `CurrencyConverter.convertCurrency(newCurrency, expenseList)` and `CurrencyConverter.convertCurrency(newCurrency, savingList)`. +4. Within each `convertCurrency` call, the amounts of `Expense` or `Saving` objects are converted to the `newCurrency` using the `convertAmount` method. +5. The `setAmount` and `setCurrency` methods of `ExpenseList` and `SavingList` are used to update the amounts and currency codes. +6.
