Programmers Poem

Single responsibility to single method
No more than 10 lines of code in a method.

when ever you see extract it right away
have your code comments on the way

use shortcuts on your side
IntelliJ is the best ide to slide

move the responsibility to the classes of its own
let all the functionalities sit under a single gown

there are 3 types of classes
entities, VOs and containers

let your code be like a poem
then sing the above song ahem ahem 

single lines for every switch
learn how to clear the cross stitch

love your reader who does not code
practice for ever learn to decode

when you see in IDE Grey/Red/Yellow/Blue/Green
Alt+Enter is for your clean

for a class or a method if you don't find any good name
prefer to jump on possible blames :P
