5,105 PointsHow do I compare scrabble tiles?
What do I compare the tile to, in the for each loop?
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;
}
}

56,414 PointsIn 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.
