Problem 5: (Practice Problem: Due Tuesday 4/21/2020)Write a method, getFoodCost which takes three arguments: the first oneis a string named fooditem, the second one is an array of string calleditems, and a third one is an array of double called price. So, when theuser gives a food item name it finds the item in the items array and getsthe corresponding price from the price array. It returns the price whichis a double to the caller.

1. Deck.java The Deck class represents a deck of cards. It starts off with 52 cards, but as cards are dealt from the deck. the number of cards becomes smaller. The class has one private instance variable that stores the Cards that are currently in the Deck: private Card] carde; Important Note: The first Card in the array will be considered the card that Is at the top of the deck. Whon cards aro removed from the deck they will be removed from the front of the array. You must implement the flollowing methods for the Deck class: • public Dock) This constructor initializes the Deck with 52 card objacts, representing the 52 cards that are in a standard deck. The cards must be ordered as in the diagram below: Important: The FIRST card in your array should be the Ace of Spades, and the LAST card should be the King of Diamonds. Note that in the picture below, the Ace of Spades is at the TOP of the deck, which is to the left. A234567890 J.0KA234567 25456 10KA2 S45 57|8|90U.0高 • public Deck(Deck…

void Date: addDays (int n); void Date: subtractDays(in n); The addDays method will add n number of days to the current date that's stored in Object's data. For example, object hold 4/21/2022 as the date and if user of this object calls addDays (10) method, it will add 10 days to 4/21/2022 giving a new date of 5/1/2022. There can be more complicated scenarios if you add a lot of days (for example hundreds of days) due to possible rollover of year and months. You can limit number of days to be added to 100. Just like addDays, subtractDays method will subtract number of days from the current date. Provide implementation of both functions in the class. Also modify your main function as follows:
