Transcribed Image Text:Repeat this number generation process for each order that day. For example if the following is called:
addorders (2, [Pizza, Burger], rand);
and the first two integers generated by rand are 1 and 0, the returned ArrayList should be [Pizza, Burger, Fries, Burger].
3. In the main method, use the above two methods to create a single ArrayList of the different orders placed over the course of the
entire long weekend. Then prompt the user asking what order to check (i.e. the 500th order across the entire weekend). You will print
out the food that was ordered for that order number, if it exists (it is possible there were not that many orders in the long weekend).
An example of input/output will be as follows below. Again, assume all user input will be non-negative numbers.
Note there is a newline after the last line in these examples. Additionally, note user input for checking order numbers will be 1-index based
(whereas your array is 0-index based!).
Example input/output when valid order number input by a user (user input is line 2 in this example below)
What order do we want to check?
1213
The 1213 order for the weekend was Burger.
Example input/output when in-valid order number input by a user (user input is line 2 in this example below)
What order do we want to check?
1213
We had less than 1213 orders this weekend.

Write this program using an IDE. Comment and style the code according to CS 200 Style Guide. Submit the source code file (java) below.
Make sure your source files are encoded in UTF-8. Some strange compiler errors are due to the text encoding not being correct.
The goal of this problem is to help you understand one of the key advantages of using ArrayLists. Unlike Arrays which are fixed-sized,
ArrayLists allow you to change size dynamically over the course of the program.
You will implement a short program that will create an ArrayList of all the orders a restaurant takes over a long weekend (Saturday, Sunday
& Monday). The restaurant sells three items: Burgers, Fries, and Pizza. Your job is help track what the restaurant sold and allow the user to
get easy access to the previous orders. You will implement both an Array and ArrayList in this assignment to better see the advantages of
an ArrayList.
1. You will first implement the method getUserlnput which takes as input an instance of a Scanner (scnr) and returns an array of ints.
Prompt the user asking how many orders were placed on each of the days of the long weekend (Saturday through Monday). You will
read in the input from the user and put these values into the array.
An example of input/output is shown here. Note the integer inputs are user input. You can assume the user will input valid non-negative
ints.
Example input/output (User input is lines 2, 4, 6 here in this example below)
How many orders were placed Saturday?
122
How many orders were placed Sunday?
345
How many orders were placed Monday?
1205
