JavaDriver Program
Write a driver program that contains a main method and two other methods.
Create an Array of Objects
In the main method, create an array of Food that holds at least two foods and at least two vegetables. You can decide what data to use.
Method: Print
Write a method that prints the text representation of the foods in the array in reverse order (meaning from the end of the array to the beginning).
Invoke this method from main.
Method: Highest Sugar Food
Write a method that takes an array of Food objects and finds the Food that has the most sugar. Note that the method is finding the Food, not the grams of sugar.
Hint: in looping to find the food, keep track of both the current highest index and value.
Invoke this method from main.
In C# using an array
Implement the inventory manager class. This class must have methods that do the following:
Add a new item to the inventory manager.
Remove an item from the inventory manager.
Re-stock an item in the inventory manager.
Display the items in the inventory manager.
Search for an item in the inventory manager by at least two criteria (name, price, quantity, etc.).
Test the inventory manager class with a driver program or unit tests. This may be a console application.

Write a static void method named raiseAllDesksToHighest
The method should accept an array of StandingDesk references.
If the array reference is null, or the array is empty the method can return without doing anything.
Otherwise it should adjust the heights of standing desks in the array so that they all have the height of the highest desk in the array.

You have been asked to develop the new system. You are to write an application to assign seats on each flight of the airline’s only plane (capacity: 10 seats). Your application should display the following alternatives: Please type 1 for First Class and Please type 2 for Economy. If the user types 1, your application should assign a seat in the first-class section (seats 1–5). If the user types 2, your application should assign a seat in the economy section (seats 6–10). Your application should then display a boarding pass indicating the person’s seat number and whether it is in the first-class or economy section of the plane. Use a one-dimensional array of primitive type boolean to represent the seating chart of the plane. Initialize all the elements of the array to false to indicate that all the…arrow_forward
- Code a called method that takes two parameters, an array of double as reference type and a double value. In the method, manipulate the argument by incrementing the value of the array. Note that you are not required to manipulate the entire array.arrow_forwardIn C# Use a one-dimensional array to solve the following problem. Write a class called ScoreFinder. This class receives a single dimensional integer array representing passer ratings for NFL players as an argument for its constructor. The test class will provides this argument. The test class then calls upon a method from the ScoreFinder class to start the process of finding a specific rating, which will be provided by the user. The method will iterate through the array and find any matching values. For all the matches that are found, the method will note the index of the cell along with its value. At completion, the method will print a list of all the indices and the associated scores along with a count of all the matching values.arrow_forwardQuestion: 1.

Use a loop to add 1 to each element of the array and return the array to the main method. In the main method, use a loop to add the array elements and display the result. Note: In the loops, use the array field that holds the length of the array and do not use a number for array length.arrow_forward
