Question

You work for a company that sells widgets. Large widgets sell for $49.99, medium widgets for $29.99, and small widgets are $9.99. Additionally, you give discounts for bulk orders. If a customer orders 10-29 widgets (inclusive), you discount 10%. If a customer orders 30-49 widgets, the discount is 20%. If a customer orders 50-69, the discount is 30%. Finally, if the customer orders 70 or more widgets, you give a 40% discount.

Write a program that will ask the customer which type of widget they want, how many, and then calculates the bill (including discount), and prints that to the screen.

Program Widgets.java

===============================================

//import scanner
import java.util.Scanner;
public class Widgets
{
    //create main method within the class
    public static void main(String[] args)
    {
        //declare variables and strings
        double price;
        int type;
        String name;
        //scanner object
        Scanner input=new Scanner(System.in);
        //Tree type
        System.out.print("Widget types 1.Large 2.Medium 3.Small ");
        System.out.print("Please enter the type of widget:");
        type=input.nextInt();
        //if/else statements
        if(type==1) { name="Large Widget"; price=49.99; }
        else if(type==2) { name="Medium Widget"; price=29.99; }
        else if (type==3) { name="Small Widget"; price=9.99; }
        else { price=0; name="Invalid"; }
        //output
        System.out.print("How many do you want of "+name+": ");
        int a=input.nextInt();
        if(a>=10 && a<=29)price=(price*a)-(0.1*price*a);
        if(a>=30 && a<=49)price=(price*a)-(0.2*price*a);
        if(a>=50 && a<=69)price=(price*a)-(0.3*price*a);
        if(a>=70 )price=(price*a)-(0.4*price*a);
        System.out.println("Total cost is: "+price);
    }
}
