The types are incompatible because "String[]" is an array of Strings: a block of memory that holds zero, one, or more String objects. Thus, you can't set the value of one String to be the value of zero or more other Strings.

Can you explain what you're trying to do. Yes, you're trying to assign a String[] to a String, but back up. Why do you want to do that? Are you trying to get the first String from the array? If so, you wantOr, are you trying to contatenate all the Strings in the array into a single String (add them together)? If this is what you want, you can use the addition (+) operator on Strings.
