I would try to simply things by using a JTable to display such data, with each column displaying a database field. I'd add an extra column, say a Boolean column that displays as a check box, and then assess the state of that column when needing to decide which to add to a cart.
我尝试使用JTable来显示这些数据，每个列都显示一个数据库字段。我将添加一个额外的列，比如一个作为复选框显示的布尔列，然后在需要决定向购物车添加哪个列时评估该列的状态。

编辑你问:
how will i know how much quantity of that product is selected,
我怎么知道选了多少产品，
Then add a quantity field as well, perhaps one that uses a JSpinner as its editor.
然后添加一个quantity字段，可能是使用JSpinner作为编辑器的字段。
and also i am thinking to add image of that product also can i do it in Jtables
我也想添加那个产品的图像我也可以在Jtables中做。
Absolutely. It knows how to display ImageIcons for instance. Please have a look at my answer to another question for an example.
绝对的。例如，它知道如何显示图像图标。请看我对另一个问题的回答。

You should create a JPanel (called PanelButton) which contents [Add to cart] button.
您应该创建一个包含[添加到购物车]按钮的JPanel(称为PanelButton)。
In other JPanels, you add PanelButton.
在其他jpanel中，添加PanelButton。
So, by this way, you can reuse your button without implement a lot of [Add to cart] button for each panel.
因此，通过这种方式，您可以重用按钮，而不必为每个面板实现大量的[Add to cart]按钮。
