Keep your methods short and focused on a single responsibility. Small methods are easier to read, easier to test, and crucially, much easier for the JIT compiler to inline and optimize.
Software entities should be open for extension, closed for modification.
Testing is not an afterthought. Utilize JUnit 5 and Mockito to build a robust safety net. Focus on writing integration tests that validate business behavior rather than micro-testing internal implementation details that are subject to change.
