The usage of method .toLowerCase()
When converting the character to lower case, can we use letter.toLowerCase() instead of Character.toLowerCase(letter)?

they are two different methods, one string and one char. the string method is called on a string you want lowered, and takes no argument - myString.toLowerCase(). the char method is static and is thus called on the Character class with the char to be lowered as the argument, Character.toLowerCase(myChar).
