How is the process of building and compiling the project carried out in your system?

The process of building and compiling a Java project typically involves several stages:

1. Compilation of source code — converting .java files into bytecode .class files using the javac compiler.
2. Resource processing — copying and packaging configuration files, images, and other resources.
3. Testing — running unit tests to verify code correctness.
4. Packaging — creating an executable file, such as .jar or .war.

To automate these steps, build systems like Maven or Gradle are often used. For example, with Maven, simply run:

mvn clean package

which cleans previous builds, compiles the code, runs tests, and packages the project.

Some projects may also use CI/CD systems that automatically trigger builds upon each code change.
