I have to receive user input via the scanner, and then
check if the word they entered contains upper or lowercase letters,

would the method isUpperCase & isLowerCase work??
If so how would you apply it to strings.

Or would i have to use string.length and char.At??

Thanks any help is appreciated

Yes you should loop over the String with the help of String.length and String.charAt(index);

Or, alternatively:
for(char character : string.toCharArray() ){
   //do stuff with character.
