Recommended Order of modifiers in Java

The Java Language Specification recommends listing modifiers in the following order:

1. Annotations

2. public

3. protected

4. private

5. abstract

6. static

7. final

8. transient

9. volatile

10. synchronized

11. native

12. strictfp

Not following this convention has no technical impact, but will reduce the code’s readability because most developers are used to the standard order.

Noncompliant Code Example

static public void main(String[] args) {   // Noncompliant}

Compliant Solution

public static void main(String[] args) {   // Compliant}
