: Favor immutable classes (like String ) to make code thread-safe and less buggy.
The book’s mantra is: If you follow these patterns, your code will be idiomatic and maintainable. To help you apply these concepts: : Favor immutable classes (like String ) to
: Enums are full-fledged classes providing type safety and powerful features. : Favor immutable classes (like String ) to
: Use this when constructors have many parameters (especially optional ones). : Favor immutable classes (like String ) to
: Always override them together. If you break this, HashMap and HashSet will fail.
: Implement it for any class with a natural ordering. 3. Classes and Interfaces
: Use them to make code concise, but don't overcomplicate simple logic. 5. Methods and Exceptions
