577 PointsHow to use "if" operator in boolean method and return true/false?
Task was: Correct the existing hasTile method to return true if the tile is in the tiles field, and false if it isn't. practice returning the result of the expression that uses the index of a char in a String.
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
return false;
}
}

return tiles.indexOf(tile) > -1;
if the index it return is greater than 1 then the tile is in the tiles and it return true, if not it return false.
