Additional Notes
Enums and Invalid States?
Track: Java
Topic: Modern Java
Focus: Enums
Java: Enums
Answer
Enums restrict values to predefined constants, avoiding invalid states.
Enums naturally prevent invalid states by limiting possible values. This ensures that when using enums, like PaymentStatus with values such as PAID and UNPAID, you can't accidentally use an invalid string like 'PAIDED'. This strengthens code reliability.
