Code Market

Java supermarket management

Code Market is a PC management game where you run a supermarket by programming a robot in Java. Instead of clicking to sell goods, you write code that tells the robot where to go and what to do: move to a rack, pick up tomatoes, take a customer’s order, or pack a bag. You start with basic commands such as robot.move(Direction.UP) and unlock more language features through a tech tree.

Writing and running code

The game uses real Java, including variables, loops, methods, arrays, lists, maps, classes, and inheritance. A built-in reference explains commands and includes examples you can copy. You keep code in files and folders, run several scripts, and check errors and logs in the game.
