Both administrators and sellers can use the Supermarket Management System's capabilities, which is powered by Java Swing. The administrator is capable of the following:

• Add Seller: The system's administrator is able to add new sellers.
• Manage Products: The administrator has control over the stock of products at the supermarket. This involves putting new products into the inventory, changing current products' name, price, and quantities, and taking existing products out of the inventory.
• Management of Stock: The administrator has control over the products' stock levels. This entails keeping track of the number of each item on hand and updating it as items are bought or refilled.
• Transactions and Payment Information: The administrator has access to transaction and payment information. This enables them to monitor sales, payments, and other aspects of the supermarket's finances.

• Sell Products: By choosing products from the inventory and putting them on the customer's shopping list, the seller can generate sales.
• Make Payment: The buyer may process payments for their purchases from the seller.
