This is a Java application that simulates a stock market, slightly inspired by the brazilian stock market (B3). It was developed as a final assignment for the Modular Programming course as part of my Software Engineering program at PUC Minas University.
As the project purpose is to learn about modular programming, it explores a bunch of advanced concepts, such as:
- Design Patterns (Decorator, Observer, Singleton and Factory)
- SOLID principles
- Unit testing and mocking
The code is thoroughly documented and should be easy to understand and add new features.
To build and run the simulation, make sure you have the following installed:
- Java SDK 20 or higher
- Maven 4.0.0 or higher
Then, run the following commands from the project root directory:
mvn clean install
java -jar target/stockmarket-1.0-SNAPSHOT.jarThe main class is called App.java. When executed, it initiates the simulation, creating a thread for each broker. These threads observe random stocks and register random buy, sell and info operations to the stock market. There is also a thread for processing the registered operations to each operation book.
