Incompatible Type?

Question

Trouble at the end of this code involving incompatible types within word = listEasy.get(wordArrayLocation); along with the other two in that method. Says it needs a java.lang.String.
import java.util.Random;
import java.util.Scanner;
import java.util.ArrayList;
import java.io.FileReader;
import java.io.IOException;
import java.io.FileNotFoundException;
import java.lang.String;
public class WordArray
   public WordArray() throws FileNotFoundException
      Creation of 3 word arrays based off of the desired level of game difficulty
      ArrayList<String> listEasy = new ArrayList<String>();
      ArrayList<String> listIntermediate = new ArrayList<String>();
      ArrayList<String> listHard = new ArrayList<String>();
      //open the physical files (words*.txt) for use in the corresponding ArrayList
      FileReader readerEasy = new FileReader("wordsEasy.txt");
      FileReader readerIntermediate = new FileReader("wordsIntermediate.txt");
      FileReader readerHard = new FileReader("wordsHard.txt");
      use a Scanner object called "in*" to access the respective file handle.  
      Scanner inEasy = new Scanner(readerEasy);
      Scanner inIntermediate = new Scanner(readerIntermediate);
      Scanner inHard = new Scanner(readerHard);
   Use a loop to walk through the input file WordsEasy.txt reading one line at a time. 
   while (inEasy.hasNext())
      String record = inEasy.next();
      listEasy.add(record);
   Use a loop to walk through the input file WordsIntermediate.txt reading one line at a time. 
   while (inIntermediate.hasNext())
      String record = inIntermediate.next();
      listIntermediate.add(record);
   Use a loop to walk through the input file WordsHard.txt reading one line at a time. 
   while (inHard.hasNext())
      String record = inHard.next();
      listHard.add(record);
   inEasy.close();
   inIntermediate.close();
   inHard.close();
   set ListEasy's size
   public int setListEasySize()
      listEasySize = listEasy.size();
   set ListIntermediate's size
   public int setListIntermediateSize()
      listIntermediateSize = listIntermediate.size();
   set ListHard's size
   public int setListHardSize()
      listHardSize = listHard.size();
   public int setGeneratorLength(int difficultyLevel)
      if (difficultyLevel == 3)
         generatorLength = listHardSize - 1;
      else if(difficultyLevel == 2)
         generatorLength = listIntermediateSize - 1;
      else
         generatorLength = listEasySize - 1;
      Picks a random word
      @return
   public int randWord()
      Random generator = new Random();
      wordArrayLocation = generator.nextInt(generatorLength);
   public String getWord(int difficultyLevel)
      if (difficultyLevel == 3)
         word = listHard.get(wordArrayLocation);
      else if(difficultyLevel == 2)
         word = listIntermediate.get(wordArrayLocation);
      else
         word = listEasy.get(wordArrayLocation);
      return word;
   private String word;
   private int wordArrayLocation;
   private int generatorLength;
   private int listEasySize;
   private int listIntermediateSize;
   private int listHardSize;
   private ArrayList<WordArray> listEasy;  
   private ArrayList<WordArray> listIntermediate;
   private ArrayList<WordArray> listHard;
}

Answer 1

Here is what I have changed things to...
import java.util.Random;
import java.util.Scanner;
import java.util.ArrayList;
import java.io.FileReader;
import java.io.IOException;
import java.io.FileNotFoundException;
import java.lang.String;
public class WordArray
   public WordArray() throws FileNotFoundException
      Creation of 3 word arrays based off of the desired level of game difficulty
      //open the physical files (words*.txt) for use in the corresponding ArrayList
      FileReader readerEasy = new FileReader("wordsEasy.txt");
      FileReader readerIntermediate = new FileReader("wordsIntermediate.txt");
      FileReader readerHard = new FileReader("wordsHard.txt");
      use a Scanner object called "in*" to access the respective file handle.  
      Scanner inEasy = new Scanner(readerEasy);
      Scanner inIntermediate = new Scanner(readerIntermediate);
      Scanner inHard = new Scanner(readerHard);
   Use loops to walk through the input file reading one line at a time. 
      while (inEasy.hasNext())
         String record = inEasy.next();
         listEasy.add(record);
      while (inIntermediate.hasNext())
         String record = inIntermediate.next();
         listIntermediate.add(record);
      while (inHard.hasNext())
         String record = inHard.next();
         listHard.add(record);
   inEasy.close();
   inIntermediate.close();
   inHard.close();
   set the size of of the arraylists to a variable.
   public void setListEasySize()
      listEasySize = listEasy.size();
   public void setListIntermediateSize()
      listIntermediateSize = listIntermediate.size();
   public void setListHardSize()
      listHardSize = listHard.size();
   //Set the difficulty level from user input  
   public void setDifficultyLevel(int difficulty)
      difficultyLevel = difficulty;
   //Calculate the wanted randomm generator length depending on the difficulty level
   public void setGeneratorLength()
      if (difficultyLevel == 3)
         generatorLength = listHardSize - 1;
      else if(difficultyLevel == 2)
         generatorLength = listIntermediateSize - 1;
      else
         generatorLength = listEasySize - 1;
   // Calculates what random arraylist location to pull an object from
   public void randWord()
      Random generator = new Random();
      wordArrayLocation = generator.nextInt(generatorLength);
      Sets the selected arraylist object to another object
   public void setWordObject()
      if (difficultyLevel == 3)
         wordObject = (listHard.get(wordArrayLocation));
      else if(difficultyLevel == 2)
         wordObject = listIntermediate.get(wordArrayLocation);
      else
         wordObject = listEasy.get(wordArrayLocation);
      returns the word
      @return
   public String getWord()
      word = wordObject.toString();
      return word;
   private ArrayList<String> listEasy = new ArrayList<String>();
   private ArrayList<String> listIntermediate = new ArrayList<String>();
   private ArrayList<String> listHard = new ArrayList<String>();
   private String word;
   private Object wordObject;
   private int difficultyLevel;
   private int wordArrayLocation;
   private int generatorLength;
   private int listEasySize;
   private int listIntermediateSize;
   private int listHardSize;
