Can you add some comments to this code describing each part and how it works? Thanks

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;

}

}
