用java的swing做一个界面，界面可以新建商品列表，列表要求：字体微软雅黑，每个列表有图标，鼠标滚轮可以控制下滑，隐藏滚动条，点击创建商品时跳出选项确认商品名称和数量

以下是一个简单的实现：

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseWheelEvent;
import java.awt.event.MouseWheelListener;

public class ProductListDemo extends JFrame {

    private JPanel mainPanel;
    private JScrollPane scrollPane;
    private JPanel productListPanel;

    public ProductListDemo() {
        setTitle("Product List");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(400, 400);
        setLocationRelativeTo(null);

        mainPanel = new JPanel(new BorderLayout());

        productListPanel = new JPanel(new GridLayout(0, 1, 10, 10));
        productListPanel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));

        ImageIcon icon = new ImageIcon("product.png");

        for (int i = 1; i <= 20; i++) {
            JPanel productPanel = new JPanel(new BorderLayout());
            JLabel titleLabel = new JLabel("Product " + i);
            titleLabel.setFont(new Font("微软雅黑", Font.PLAIN, 16));
            productPanel.add(titleLabel, BorderLayout.CENTER);
            productPanel.add(new JLabel(icon), BorderLayout.WEST);
            productListPanel.add(productPanel);
        }

        scrollPane = new JScrollPane(productListPanel, JScrollPane.VERTICAL_SCROLLBAR_NEVER, JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
        scrollPane.getVerticalScrollBar().setPreferredSize(new Dimension(0, 0));
        scrollPane.addMouseWheelListener(new MouseWheelListener() {
            @Override
            public void mouseWheelMoved(MouseWheelEvent e) {
                JScrollBar scrollBar = scrollPane.getVerticalScrollBar();
                int newValue = scrollBar.getValue() - e.getWheelRotation() * scrollBar.getUnitIncrement();
                scrollBar.setValue(newValue);
            }
        });

        JButton createProductButton = new JButton("Create Product");
        createProductButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                String name = JOptionPane.showInputDialog(ProductListDemo.this, "Enter product name:");
                if (name != null && !name.trim().isEmpty()) {
                    int quantity = 1;
                    String quantityStr = JOptionPane.showInputDialog(ProductListDemo.this, "Enter quantity:");
                    try {
                        quantity = Integer.parseInt(quantityStr);
                    } catch (NumberFormatException ex) {
                        // ignore
                    }
                    JPanel productPanel = new JPanel(new BorderLayout());
                    JLabel titleLabel = new JLabel(name);
                    titleLabel.setFont(new Font("微软雅黑", Font.PLAIN, 16));
                    productPanel.add(titleLabel, BorderLayout.CENTER);
                    productPanel.add(new JLabel(icon), BorderLayout.WEST);
                    for (int i = 1; i <= quantity; i++) {
                        productListPanel.add(productPanel);
                    }
                    productListPanel.revalidate();
                    productListPanel.repaint();
                }
            }
        });

        mainPanel.add(scrollPane, BorderLayout.CENTER);
        mainPanel.add(createProductButton, BorderLayout.SOUTH);

        setContentPane(mainPanel);
        setVisible(true);
    }

    public static void main(String[] args) {
        new ProductListDemo();
    }
}

界面效果如下：
