2,060 PointsStuck with this question, it wants me to return true if the tile is in the word and false if it isnt.
Really stuck with this.
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;
}
}

You need to use the String.indexOf(char) method to determine whether the char tile is present in the String tiles .
IF it is true, meaning the tile is present inside String tiles then it will return an integer > 0. IF false meaning the char tile is not present inside String tiles then it will return -1. Thus we can use this principle to test the hasTile method. Please remember the method hasTile returns boolean not int. This is how I do it:
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 (tiles.indexOf(tile)>0);//<-- this will return TRUE if tile is inside tiles and FALSE if vice versa.
}
}
I hope this can help a little
