Improving Menu Item Search App - Functions for Printing and Searching Menu Items

Function 1: PrintMenuItemDetails

1. Write a function PrintMenuItemDetails (MenuItem) to print the details of the menu item. It takes in a MenuItem object as its argument and has no return value. This function improves maintainability.

You must use the get functions created in requirement 1 to retrieve the menu item details for printi
 
2. Write a function SearchBasedOnNameOrCategory(searchString, listOfMenuItems) to search the matching menu items from a provided list of items with the matching searchString. It takes in a searchString of type String and listOfMenuItems of type List as its arguments and returns a searchResult of type List.

3. Convert the list of Strings with menu items details to store list of menu item objects instead.

4. Read in the menu item details from input.txt file (use the readLines() function) and put them into a list listOfMenuItems. You are required to create the Menu item object to store the menu item attributes and append each of them into listOfMenuItems. Make sure to close the file after reading the data.

Hint: You have to use the split() function to retrieve the menu item attributes and strip() and/or replace() function to remove any trailing spaces and “\n” in the attributes.

5. During the printing of the menu item details, all parts of the code that prints the menu item details uses the PrintMenuItemDetails() function created in item 2.

For example:

Name: Hawaiian Pizza

Category: Pizza

Write a function SearchBasedOnNameOrCategory(searchString, listOfMenuItems) created in requirement 3 to perform the search and retrieve the search results instead.
