Java Coding Standards

Standards for readable, maintainable Java (17+) code in Spring Boot services.

Core Principles

• Prefer clarity over cleverness
• Immutable by default; minimize shared mutable state
• Fail fast with meaningful exceptions
• Consistent naming and package structure

Naming

// ✅ Classes/Records: PascalCase
public class MarketService {}
public record Money(BigDecimal amount, Currency currency) {}
