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(){ int tileCount=0; for (char tile: mHand.hasTile()){ if(mHand.indexOf(tile) > -1){ tileCount++; } } return tileCount; } }

Hi Solange,

here a code proposal:

public int getTileCount(char tile){ 
  // to proof a specific char inside mHand you need to give that chat as parameter
  int tileCount=0; 
  for (char tileToProof: mHand.toCharArray()){
    // you cant use hasTile() method on mHand because mHand is a String
    // to compare chars inside a String mHand you need to "convert" String mHand in an array of chars using toCharArray()
    // inside the for loop you want to compare every char from the mHand-array with your argument "tile"
    if(tileToProof == tile){ 
      // condition to increment tileCount
      // if a char from mHandArray equals to the argument char 
      // increment the count
      tileCount++; 
    } 
  } 
  return tileCount; 
}
