= code cleanup
- for loop replaceable with enhanced 'for' loop - using diamond in generic type - collapse try catch exception - using try-with-resource - using List#sort instead of Collections#sort - replaced lambda with method reference - using native compare method to compare numbers - using switch instead of if for in ESSyncUtil
