Question

Our company uses checkstyle to ensure the java source code having no nested if..else. i am trying to get used to it. but i have this doubt, is this a efficient way to improve code quality?

we have many rules,

1. no nested if else
2. Method should be no longer than 50 lines.
3. anonymous inner class no longer than 15 lines.
4. there must be a white space before {, which means we have to use Ctrl+Shift+F to format code.
