i have to know how many tile of a specific character they actually have by adding a new method "getTileCount"

it uses the "for" each loop through the character and increment a counter if it matches i have to return the count thx guys !

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;
  }
}

You can use the toCharArray() method of the String class to turn the string mHand into an array of chars that you can loop through, using the for each loop. Initialize an int variable to zero to keep track of the count. Then in each iteration of the loop increment that variable if the current character in the array is the same as tile:

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) {
    int count = 0;
    for (char character: mHand.toCharArray()) {
      if (character == tile) {
        count++;  
      }
    }
    return count;
  }
}
