Create two files to submit:
ItemToPurchase. java - Class definition
ShoppingCartPrinter. java - Contains main() method
Build the ItemToPurchase class with the following specifications:
Private fields
String itemName - Initialized in default constructor to "none"
int itemPrice - Initialized in default constructor to 0
int itemQuantity - Initialized in default constructor to 0
Default constructor
Public member methods (mutators & accessors)
setName() & getName()
setPrice() & getPrice()
setQuantity() & getQuantity()
(2) In main(), prompt the user for two items and create two objects of the ItemToPurchase class. Before prompting for the second item, call scnr. nextLine(); to allow the user to input a new string.

Explanation:

public class ItemToPurchase {

private String itemName ;

private int itemPrice;

private int itemQuantity;

public ItemToPurchase(){

itemName = "none";

itemPrice = 0;

itemQuantity = 0;

}

public String getName() {

return itemName;

}

public void setName(String itemName) {

this.itemName = itemName;

}

public int getPrice() {

return itemPrice;

}

public void setPrice(int itemPrice) {

this.itemPrice = itemPrice;

}

public int getQuantity() {

return itemQuantity;

}

public void setQuantity(int itemQuantity) {

this.itemQuantity = itemQuantity;

}

}
