    Default Arrays and array list

    Creating a name class for monsters using arrays and array list. The goal is to randomize the monster names that are being generated. Any help would be greatly appreciated. Thank you.

    package character;
    import utility.SingleRandom;
    import java.util.ArrayList;
    import java.util.List;
    import java.util.Arrays;


    /** Creates a name class for the monsters

    public class Names
    {
    // instance variables
    private final String nameList;

    // class variables
    private static final String [] MONSTERNAMES = {"Cletis","Gomez","Pritus","Selus","Teether"};
    //private static final int [] NUMBERNAMES = NUMBERNAMES.length;
    private static final int [] NUMBERNAMES = 5;
    MONSTERNAMES = new int[NUMBERNAMES];



    //Static Variables

    //This is the single instance accessed by members of
    // other classes via the getInstance() factory method
    private static Names instance;
    static //static initializer: This instantiates it once
    {
    instance = new Names();
    }
    ArrayList<String> namesList = new ArrayList<String>();

    /** Constructs a names list with monster name array
    */
    private Names()
    {
    List<String> listMonsters = Arrays.asList(MONSTERNAMES);

    }
    private Names ArrayList(Collection<String>listMonsters)
    {

    }
    // Instance methods
    /** Gets max names to start in array
    /*
    * @return NUMBERNAMES
    */
    // accessors
    private int getMaxNamesToStart()
    {
    return NUMBERNAMES;
    }

    /** Gets the current number of names in the array
    * return listMonsters
    */
    public int getNumberOfNames()
    {
    return listMonsters;
    }
    /** Gets the name of the monster
    * @return nameList
    */
    public String getName()
    {
    return MONSTERNAMES[2];
    }
    /** finds the name of the monster
    * @return index[MONSTERNAMES]
    */
    public String findName()
    {
    return index[MONSTERNAMES];
    }
    /** predicate or boolean for name
    * @return name
    */
    public boolean hasName()
    {
    return MONSTERNAMES.equals(nameList);

    }


    public hasNames()
    {
    return MONSTERNAMES.equals(listMonsters);
    }



    }

    Put the name Strings in a list and randomize it using the Collections class's shuffle() method.

    If you are creating the names, what do you mean by "randomize"?

    We are using the Singleton Random class for this assignment. I think we are using one instance in the names class to randomize the monster names. Thank you for reviewing my post.
