Java 1
The Assignment
This program will display a menu to the user from which they can choose an option for the sale of one of three products.
Once the menu selection is made, the user will be prompted for the quantity of the product that is being purchased.
When the quantity has been entered, the program will look up the price of the item. If three or more items of the same type are purchased, a 5% discount will given on the purchase of that item.
A tally of total sales are kept as the program and can be viewed from a menu option.
2.1. Specifications
Use two separate files with a single class in each one (there could actually be more classes, but two will keep it more manageable).
Name the first file (and class) ProductsSold. This is the one that will have all of the methods other than the main method.
Name the second file TestProductsSold. This file will contain the class that has the main method and the logic which controls the program.
There are three products that are sold from the menu: Widget1, Widget2, and Widget3.
There will be a menu option for each of these items plus options to view sales totals and to exit. On the option to exit, use the System.exit(0) statement.
Use methods to accomplish each of the necessary tasks. For instance, you will need a method to calculate the sales tax, a tally method for each of the three products, a method to look up the price of the product, a method to calculate the discount, a method to display the total sales for all of the products, and a method to display the menu. You may need others as well, depending upon the logic.
Use getters and setters where necessary.
The logic flow will be something like the following:
The user makes a selection from the menu to sell one of the three products.
The user will then be prompted for the quantity of that item.
The program will look up the sales price of that item.
The program will calculate the total sale of the item.
If three or more of those items were purchased, the program will calculate a discount and give the 5% discount.
The tally for the total sales for that item will be updated for this item.
At any time, the user can take the option to display the total sales for each of the three products.
2.2. Output Format
There are several ways in which this program could be written. However, in order to grade for following specifications and to have a clear path to a solution, it is required that you write your program using the specifications below.Explanation / Answer
The required code is as follows. I tried to keep it as simple as I can and hope that I have succeeded in it. Hope you'll understand the code.So here comes the code:
Cust.java
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
public class Cust {
public int id;
String name;
int phoneNo;
ArrayList<prod> al=new ArrayList<prod>();
public void BookedProd(prod object){
object.setprodStat("unavailable");
al.add(object);
}
public int getID() {
return id;
}
public void setID(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getNo() {
return phoneNo;
}
public void setNo(int phoneNo) {
this.phoneNo = phoneNo;
}
public Cust(int id, String name, int phoneNo) {
super();
this.id = id;
this.name = name;
this.phoneNo = phoneNo;
}
}
class prod {
public int prodID;
String prodName;

}
public void setprodStat(String prodStat) {
this.prodStat = prodStat;
}
