765 Pointsi used the code send by treehouse community but it is still showing the following error
Bummer! While you could definitely solve this using an if statement, try returning the result of the expression.
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) >= 0){
return true;}
else
{return false;}
}
}

It's about this method:
public boolean hasTile(char tile) {
// TODO: Determine if user has the tile passed in
if(tiles.indexOf(tile) >= 0){
return true;}
else
{return false;}
}
The expression you pass to the if statement is called a boolean expression (the bit between the parentheses, 'tiles.indexOf(tile) >= 0'). A boolean expression is either true or false.
What you're doing right now is basically this: "If 'boolean expression' is true, return true. If 'boolean expression' is false return false".
Instead you can just write "return 'boolean expression'".
It's the same thing, and it's faster, easier to read, no unnecessary lines :-)
