These are String methods that are useful for accessing information about Strings
charAt (index) – the character at the specified index
length() – the number of characters in the String
isEmpty() – true if length is 0 or false otherwise
indexOf (item) – the index of the first item it finds, or -1 if not found
substring (startIndex, endIndex) – a substring from the starting index position to the end index
