Write a program to keep track of a hardware store’s inventory. You will need to create necessary classes for handling the data and a separate client class with the main method.

The store sells various items. For each item in the store, the following information is maintained: item ID, item name, number of pieces currently in the store, manufacturer’s price of the item and the store’s selling price. Create a class Item to store the information about the items. Provide appropriate setters and getters. Override the toString() method.

Create a class Inventory that contains a vector of items. This class will contain a bunch of methods to help build the application. Create a static variable to keep track of the total different items in inventory. Every time a new item is added to the inventory this variable has to be updated.

1. A method to create 5 Item objects by initializing the following properties of Item and returning a vector of Item.

ItemID,itemName,pInstore,manufPrice,sellingPrice

2. A method to check whether an item is in the store by doing a lookup in the vector.
3. A method to update the quantity on hand for the item being sold
4. A method to report the quantity on hand for any item requested during purchase
5. A method to print the report for the manager in the following format

ItemID     itemName               pInstore        manufPrice     sellingPrice

12            Circular saw            150               45.00      125.00

235        Cooking Range          50                450.0             850.00

.

Total Inventory: $####.##

Total number of items in the store:

The total inventory is the total selling value of all the items currently in the store. The total number of items is the sum of the number of pieces of all items in the store.

Create a separate client class with the main method, display the menu and use switch case statement to execute appropriate method. The main method should display a menu with the following choices such as:

1. Check whether an item is in the store
2. Sell an item
3. Print the report

For option 1, the user must also be prompted for the itemID. You will then call the method created in the Inventory class.

For option 2, verify if pInstore > qtyOrdered. You will invoke the method created in Inventory class.

For option 3, display the report. Again, this is nothing but executing method from Inventory class.

Also after an item is sold update the appropriate counts. Initially, the number of pieces in the store is the same as the number of pieces ordered and the number of pieces of an item sold is zero. You will use the utility method created as part of Inventory class.

Create an application named SalesLeader.

Add a class to your project called SalesPerson. (The default class may be called Program. Do not change this)

The SalesPerson class contains the following Properties:

FirstName - The salesperson's firs name (as a string)

SalesAmount - The sales amount ( as a double)

SalesArea - The 3 areas are the enumeration West Coast, MidWest, and East Coast.

Add a constructor which sets FirstName to "None", SalesAmount to 0 and SalesArea to MidWest.

Add a method which checks if the SalesAmount is greater than $100,000. If so, add 10% to the SalesAmount.

In the main class (Program), create the following:

Create 3 objects from SalesPerson.

                salesperson1

                salesperson2

                salesperson3

Prompt the user to set the amount of sales, first name and sales area for each object.

Display the name, sales amount and area for each sales person. Display which sales person is the Sales Leader this month and their commission (15% of total sales) … but first, add a method SalesLeaderTie to Program class to check if there might be a tie for Sales Leader. (Write Code in C#).

How would your ecological footprint be different if you lived in a less industrialized country?

1- How does the demand curve show the marginal benefit received by consumers?

2- How does a supply curve show the marginal cost to producers?

3- What is a perfectly competitive market?

4- What can eliminate a shortage?

5-What can reduce a surplus?

This is a homework question. It has to be done using JAVA language. And PAY ATTENTION TO WHAT YOU CAN USE AND WHAT I SPECIFICALLY ADDED THAT CANT BE USED TO COMPLETE THIS.

Objective:

Write a program that takes in two words, and then it recursively determines if the letters of the first word are contained, in any order, in the second word. If the size of the first word is larger than the second then it should automatically return false. Also if both strings are empty then return true.

You May NOT: ******************************************************************************************

Use any iterative loops. In other words, no for-loops, no while-loops, no do-while-loops, no for-each loops.

Use the string method .contains(String)

You May: ******************************************************************************************

Use the string method .charAt(Index)

Hints:

Recursive methods generally attempt to solve a smaller problem then return the results of those in order to solve the larger one.

Think of how to do this with a loop, and use that to guide what parameters you’ll need for your recursive method.

Enter 2 words. I will determine if the letters of one is contained in the other

5. Opportunity cost and production possibilities

Eric is a skilled toy maker who is able to produce both cars and drums. He has 8 hours a day to produce toys. The following table shows the daily output resulting from various possible combinations of his time.

On the following graph, use the blue points (circle symbol) to plot Eric's initial production possibilities frontier (PPF).

Initial PPFNew PPF012345678302520151050DRUMSCARS

Suppose Eric is currently using combination D, producing one car per day. His opportunity cost of producing a second car per day is   per day.

Now, suppose Eric is currently using combination C, producing two cars per day. His opportunity cost of producing a third car per day is   per day.

From the previous analysis, you can determine that as Eric increases his production of cars, his opportunity cost of producing one more car   .

Suppose Eric buys a new tool that enables him to produce twice as many cars per hour as before, but it doesn't affect his ability to produce drums. Use the green points (triangle symbol) to plot his new PPF on the previous graph.

Because he can now make more cars per hour, Eric's opportunity cost of producing drums is   it was previously.
