how to get the tile count?

i seem to be counting the total number of characters , but here i need to match the character from the string and increment the counter depending on the number of times it occurs

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 tiles)
  {
    int tileCount = 0;
  for (char tile: mHand.toCharArray())
  {
    if(mHand.indexOf(tiles)>=0)
    {
      tileCount++;
    }

  }
     return tileCount;
  }

}

The argument passed in should only be one tile so you do not need mHand.indexOf() in there. Try:

if(tile == tiles)
  tileCount++;

"tile" is your variable that is temporarily holding the char each time through the loop, so you want you use that to compare to the tile that is passed in as an argument. Also, the parameter "tiles" is a little misleading because only one tile will be passed in the method at any given time; so I would change it to "tile" and make your variable in your for loop something like "letter". The idea behind it is to make your program as clear as possible for other developers so they won't have to rely on comments and inquiries for understanding.
