Meaning that if the char is contained in the string, the method will return any integer >= 0. If not, it will return -1.
public class ScrabblePlayer {
private String mHand;
public ScrabblePlayer() {
mHand = "";
}
public String getHand() {
return mHand;
}
public void addTile(char tile) {
// Adds the tile to the hand of the player
mHand += tile;
}
public boolean hasTile(char tile) {
if(mHand.indexOf(tile) >= 0) { // Checks if the tile is in the hand.
return true; // If it is, we return true.
} // By this point, we know that if the code reaches below this if statement, the tile is not in the hand, so we can return false.
return false;
}
}
