0/2 File Limit (b) Write the UserNane method setAvailableuserNames. The method removes from possibleNanes all names that are found in usedNames. These represent user names that have already been assigned in the online system and are therefore unavailable. A helper method, isised, has been provided. The isused method searches for name in arr. The method returns true if an exact match is found and returns false otherwise The example below shows the intended behavior of the setAvalableuserNames method.

You must use isused appropriately to receive full credit. Complete the setAvailableuserNanes method below. ** Renoves strings from possibleNanes that are found in usedNanes as described in part (b). public void setAvailableuserNanes (Stringl) usedNanes) public class UserName // The 11st of possible user names, based on a user's first and last names and initialized by the constructor. private ArrayList<Strings possibleNanes; /* Constructs a UserName object as described in part (a). * Precondition: firstName and lastNane have length greater than e * and contain only uppercase and lowercase letters. public UserName(String firstNane, String lastNane) ( /* to be implenented in part (a) /) /* Returns true if arr contains name, and false otherwise. / public boolean isused(String name, String[] arr) (* inplenentation not shown /} ** Removes strings from possibleNanes that are found in usedNanes as described in part (b). public void setAvailableuserNames (Stringt) usedNanes) { to be ieplenented in part (b) "/) (a) Write the constructor for the UserName class. The constructor initializes and fils possibleNames with possible user names based on the firstNane and lastNane parameters. The possible uner names are obtained by concateniating lastNane with different substrings of firstNane. The substrings begin with the first character of firstName and the lengths of the substrings take on all values from 1 to the length of firstNane. The following example shows the contents of possibleNanes after a UserNane object has been instantiated.
