yes, this solution make is great

case

I did this method, but better.

had the same problem. check the casing

lol

nice

Did you overcomplicate this? Christ how many things you importing dude?

How did I not think of this? LOL

yeah, it's crazy educational to read how other coders solved the kata so you can figure out ----> WTF

after hours I got it. I just wrote sentence.toLowerCase(); not sentence = sentence.toLowerCase(); crazy

I have spent hours debugging this thing. When I run it in my ied everything is buttery smooth. I am confident that there is something wrong with the kata unless you can prove me wrong. and yes I did sentence.toLowerCase();

Just read the f..riendly manual

well, you did better at code formatting the first time... x)

I know why, but I won't tell you. Most important thing for a developper: learn how to properly debug your own code. But I can give you some advises:

• if you code on an IDE, use the debugger to go through the execution of your code step by step, to see how every variable evolves
• if you don't and work directly on cw, use the "old tools": System.out.println(...) and print what you need at appropriate places

And I'd finally suggest that you apply your code to that input: "aaaaaaaaaaaaaaaaaaaaaaaaaa"... ;)
