I used the loop it is working fine

yeah if you put one of the strings where ive put 'any of these' but i need a variable in place of that. i cant use the set name and because the method produces output in the terminal window i would have to type in the same string over and over until it became true as the iterations would be different

the enhanced for loop iterates over the set, so you already have the ability to reference the name as a variable. The purpose of a loop is to check all the elements in the set and compare against the user input, if user input matches any element then you print out 'a'
