java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Integer

I need help.

I dont understand what i did wrong.

ScrabblePlayer.java 
public class ScrabblePlayer {
  private String mHand;

  public ScrabblePlayer() {
    mHand = "";
  }

  public String getHand() {
   return mHand;
  }

  public void addTile(char tile) {
    // Adds the tile to the hand of the player
    mHand += tile;
  }

  public String getTileCount (char tile){
    String count = "_";
    for(char tiles : mHand.toCharArray()){
      char store = '-';
      if(mHand.indexOf(tile) >= 0) {
        store = tiles;
      }
      count += store;
    }
        return count;
  }

  public boolean hasTile(char tile) {
   return mHand.indexOf(tile) > -1;
  }
}

First, the return type of getTileCount should be an int. Then you want to declare and initialize a variable named count , which will be of type int. When you loop through the characters, your if statement should compare each of the tiles with the passed in tile. If you have a match then increment the count variable. Finally, return count.

 public int getTileCount (char tile){
    int count = 0;
    for(char tiles : mHand.toCharArray()){
      if(tile == tiles) {
         count += 1;
      } 
    }
        return count;
  }

Hope this helps.
