Incompatible types: unexpected return value return counter; ^

What am I doing 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 boolean hasTile(char tile) {
   return mHand.indexOf(tile) > -1;
  }
  public void getTileCount(char tile){
    int counter = 0;
    for (char t: mHand.toCharArray()){
      if( tile == t ){
        counter ++;
      }
    }  
    return counter;

   }
}

Change your return type in the getTileCount signature to be int instead of void.

Your method returns an int, because you defined the counter variable as an Integer. If you define your method with void, this method wan´t return nothing :)
