* Remove redundant statements, declarations, type parameters, casts, etc
* Add braces to all control flow statements
* Mark methods private where possible
* Simplify boolean expressions (eg `b == true`)
* Replace `for(;;)` with `for(:)` where possible

* Narrow catch clauses
* Ensure method names are in lowerCamelCase and classes in UpperCamelCase
* Ensure variable names are in lowerCamelCase or ALLCAPS
* Mark variables private where possible (ignoring variables in all caps)
* Remove unused methods and variables (ignoring incomplete methods,
members that are used in commented-out code, alternative sorting
algorithms, and utility methods)
