Java Web Development Techdegree Student 646 Pointsoh my god, this quesiton struggles me a whole day! what's wrong!1 thank you sooo much!
I think this is right but answer said return to a result of the expression, but the result was true or false but when I return to true or false, without complie errors but I still could not pass,
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
boolean there = tiles.indexOf(tile) != -1;
if(there)
{
return true;
}
return false;
}
}

Java Web Development Techdegree Graduate 21,083 PointsThe previous answer doesn't seem readable, the image won't display. So just in case you haven't got it yet:
public boolean hasTile(char tile) {
// TODO: Determine if user has the tile passed in
return tiles.indexOf(tile) != -1;
}
You don't need the whole if / else part. 'tiles.indexOf(tile) != 1' is a boolean expression. It can only have the value true or false. Yes your code compiles, but it's unnecessary and bad practice to write:
if (true) {
return true;
} else {
return false;
}
You can just return the result of the Boolean expression directly. That's what the error message is trying to tell you.
