Issue details

Your pom.xml is already technically strong (modern Java 21, testing, quality gates). but these changes can be to even look more structured . these what the changes i tried to make i think these seems to be correct if any thing is wrong in the code please let me know.

1. Upgraded build configuration to Java 21 (LTS)
2. Enabled strict compiler checks using -Xlint:all and -Werror
3. Standardized compiler configuration using maven-compiler-plugin
4. Integrated JUnit Jupiter (JUnit 6) for unit testing
5. Added AssertJ for fluent, readable assertions
6. Added Mockito for mocking and isolated unit tests
7. Configured Maven Surefire Plugin for reliable test execution

THANK YOU
