As I write more Apex, I’ve started building utility classes to keep logic reusable and easy to manage.
These classes don’t represent data—they represent functionality. For example:
DateUtils for date formatting or calculations
EmailUtils for sending templated messages
ValidationUtils for checking business rules
What matters is:
Single responsibility: each class does one thing
Static methods: utility classes rarely need to store state
Meaningful names: clarity matters more than cleverness
It’s the difference between writing code and designing a system. And that mindset shift has made me a better developer.
