SwapHead by Chris!

I don't understand what he declared about Chris changing variables, it's just very confusing!

especially this code block, i can't follow along with Craig anymore. 

Public String swapHead(String characterName) {
String originalCharactername = this.characterName;
this.characterName = characterName; 
return originalCharactername;
}

this block is called on a character object and is used to give it a new name and then return the old name. the current name is stored, the object is given the new name that is passed in as the argument, and the old name is returned. also, to format code use the backtick (`) not the single quote (').

Original value of this.characterName is stored in the originalCharacterName as a sort of temporary variable. Then he's setting a new value ie characterName which is coming from the argument, to the private member variable this.characterName. In the end, he's returning originalCharacterName because he wants to return the previous value of the private member variable.
