2,809 PointsCorrect the hasTile method.
Hey Anders. I keep trying the problem, but I seem not to get it right for some reason. Can u tell me what is wrong with what I did on the second question?
public class ScrabblePlayer {
// A String representing all of the tiles that this player has
private String tiles;
public ScrabblePlayer() {
tiles = "";
}
public String getTiles() {
return tiles;
}
public void addTile(char tile) {
// TODO: Add the tile to tiles
tiles+=tile;
}
public boolean hasTile(char tile) {
// TODO: Determine if user has the tile passed in
if(tiles.indexOf(tile)!=-1){
// if(hasTile!=-1){
return true;}
else{
return false;}
}
}

Try this, return tiles.indexOf(tile) >=0; This test will return a boolean. You could also try != -1 as you have there in your code, but use no 'if' 'else.' Just tell the method to return the boolean evaluation in one line. See "test operators."
