What choices did you face in developing your solution, and how did you choose among them? The choices i had to face in developing my solutions would be writing the right code in my java program on the exercise 3 lesson. I would have to ethier choose if i need to use length(); or toLowerCase; or toUpperCase; which all have different functions. length(); takes a certain ammount of letters out of your string depending on where you tell it to start. toLowerCase, allows you to put all the letters in your string into lower case. toUpperCase, allows you to pull all the letters into UpperCase.
