I need help.
I dont understand what i did wrong.
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 String getTileCount (char tile){
String count = "_";
for(char tiles : mHand.toCharArray()){
char store = '-';
if(mHand.indexOf(tile) >= 0) {
store = tiles;
}
count += store;

public boolean hasTile(char tile) {
return mHand.indexOf(tile) > -1;
}
}

When you loop through the characters, your if statement should compare each of the tiles with the passed in tile. If you have a match then increment the count variable. Finally, return count.
public int getTileCount (char tile){
int count = 0;
for(char tiles : mHand.toCharArray()){
if(tile == tiles) {
count += 1;
}
}
return count;
}
Hope this helps.
