10,042 PointshasTile method??
"Can you also please help me write out the hasTile method? It should return true if the hand has the tile, and false if it doesn't. Thanks!"
I don't really understand what the hasTile method is supposed to achieve exactly.
Is it that only one of each letter is allowed in the hand (not the case in Scrabble though I don't think)? Is it checking the number of tiles in the hand against a maximum amount?
Having problems writing the code because I don't understand what the hasTile method is actually for :-(

method should return true if the hand has the tile in it.
What we know:
- function should be
public
- returns boolean (true/false)
- accepts a char input
Needs
- access hand
- determine if tile (char) is present
The "hand" is in the String field mHand
, and we learned that you can find out if a character is a member of a string using .indexOf()
. If index is 0 or positive the tile (char) is present.

// doesn't. Thanks!
public boolean hasTile(char tile) {
return mHand.indexOf(tile) >= 0;
}
