Modify the Inventory Program to use a GUI. The GUI should display the information one
product at a time, including the item number, the name of the product, the number of
units in stock, the price of each unit, and the value of the inventory of that product. In
addition, the GUI should display the value of the entire inventory, the additional attribute,
and the restocking fee.
Here is my Inventory program from 1 to 3:
package inventory_part1java;
// Inventory_Part1.java
// Inventory_Part1 program reads user information for a product, display its properties and its inventory
import java.text.DecimalFormat; // program uses class DecimalFormat
import java.util.Scanner; // program uses class Scanner
public class InventoryPart1 {
public static void main(String[] args) {
// create a tool that insure the specified format for a double number, when displayed
DecimalFormat doubleFormat = new DecimalFormat( "0.00" );
// create Scanner to obtain input from command window
Scanner input = new Scanner( System.in );
int number; // stores the user DVD number
String name; // stores the user DVD name
int units; // stores the user DVDs number of units
double price; // stores the user DVD price
System.out.print( "1 " ); // prompt
System.out.flush(); //empties buffer before you input text.
number = input.nextInt(); // read product number
while ( number < 0 ) //starts while loop to make sure a positive number is entered.
{
System.out.print( "1 " ); //prompt
number = input.nextInt(); // read product number
}
System.out.print( "Hustle and Flow. " ); // prompt
System.out.flush(); //empties buffer before you input text.
input.nextLine(); //prompt user for input
name = input.nextLine(); // read product name
System.out.print( "2 " ); // prompt
System.out.flush(); //empties buffer before you input text.
units = input.nextInt(); // read product number of units
while ( units < 0 ) //starts while loop to make sure a positivSystem.out.print( "1 " ); // prompt
System.out.flush(); //empties buffer before you input text.
number = input.nextInt(); // read product number
while ( number < 0 ) //starts while loop to make sure a positive number is entered.
{
System.out.print( "1 " ); //prompt
number = input.nextInt(); // read product number
}
System.out.print( "Hustle and Flow. " ); // prompt
System.out.flush(); //empties buffer before you input text.
input.nextLine(); //prompt user for input
name = input.nextLine(); // read product name
System.out.print( "2 " ); // prompt
System.out.flush(); //empties buffer before you input text.
units = input.nextInt(); // read product number of units
while ( units < 0 ) //starts while loop to make sure a pose number is entered.
{
System.out.print( "2 units " ); //prompt
units = input.nextInt(); // read product number of units
}
System.out.print( "$13.49" ); // prompt
System.out.flush(); //empties buffer before you input text.
price = input.nextDouble(); // read product price
while ( price < 0 ) //starts while loop to make sure a positive number is entered.
{
System.out.print( "$13.49 " ); //prompt
price = input.nextDouble(); // read product price
}
// close the reading session
input.close();
// create a Product object with the user input
Product product = new Product(number, name, units, price);
// display the product's properties and its inventory
// display the product's properties and its inventory
System.out.println(product.toString() + " has inventory value = $" +
doubleFormat.format(product.inventory()) + "3");
}
}
package inventory_part3java;
// Inventory_Part3.java
// Inventory_Part3 creates an array of DVD products, ...
// displays the information and inventory for each product, sorted by title, and the entire inventory.

I need help ASAP and be specific. Thanks
