Choosing the Right Nesting Strategy

Decide between nested class variants based on coupling, access needs, and readability.

Choosing the Right Nesting Strategy

Java offers four nesting options: top-level, static nested, inner (non-static), and local/anonymous. Choosing the right one depends on coupling, access needs, and reuse scope.

Decision Tree

Ask these questions to choose:

  1. Is the class used only inside the outer class? → Consider nesting
  2. Does it need the outer instance? → Inner class; else → Static nested
  3. Is it used only in one method? → Local class or anonymous
  4. Does it implement a single method? → Lambda
