Courses Plus Student 775 PointsI am having some trouble with this. How do I add a tile to the users hand ?
I have set up the code for the "addTile" portion of code but I keep getting return messages stating that there is another more efficient method to use. In my head the code seems correct. I could use some fresh eyes.
public class ScrabblePlayer {
private String mHand;
public ScrabblePlayer() {
mHand = "";
}
public String getHand() {
return mHand;
}
public void addTile(char tile) {
boolean gotTile = mHand.indexOf(tile) >= 0;
if (gotTile) {
mHand += tile;
}
// Adds the tile to the hand of the player
}
public boolean hasTile(char tile){
return true;
}
}

This checks what the player already has in his hand for the given Tile.
if (gotTile) {
mHand += tile;
}
Now if the player has the tile in his hand, then we add the tile to his hand. It looks like the addTile method is like drawing a tile in scrabble, doesn't matter what the player has in his hand, he just adds it to his hand. So you may be able to cut all that down just to the mHand +=tile; concatenation.
