okay, reversed.charAt(0) does not actually translate to the variable that stores the character in the position 0. It is a METHOD that returns the character in position 0. Therefore, you can't assign to it. To use a word from c++ vocab, you need to have an l-value for assignment, and reversed.charAt(0) is not an l-value. Furthermore, I'll save you from spinning ...

Oh so you can only change the string's value once. Depends what you mean by "string's value." You can never change the contents of a String object. Strings are immutable.
