How do I compare scrabble tiles?

What do I compare the tile to, in the for each loop?

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 int getTileCount(char tile){

    for(int count : mHand.toCharArray()){
      if( tile == mHand.){
        count++;
      }
    }
    return count; 
  }
}

In the for-each loop, the loop variable isn't a counter like a vanilla for loop. The loop variable is the individual item from the array. So instead of being the count, it's a tile from the hand. So you should be comparing that tile to the tile passed into the function.
