Front End Web Development Techdegree Graduate 84,738 PointsHaving a hard time with this challenge
Challenge says it wants a method named getTileCount() that accepts a char. But what it seems to want is for me to count the number of tiles in mHand - so I don't understand how I would want a char parameter if that's what they're asking for.
Also I think I have some compile errors, but I'm having a hard time figuring out how to use the workspace to debug this.
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) {
return mHand.indexOf(tile) > -1;
}
public int getTileCount(char tile) {
int counter = 0;
for (char tile: mHand.toCharArray()) {
counter++;
}
return counter;
}
}

Let me give you this alternative way of wording the challenge.
I'm going to pass in a letter in the getTile method. I want to see how many of that letter is in our mHand string. How would we be able to do that? Using your knowledge of the for-each loop, try to loop through each letter in our mHand string and check if it equals the character that was passed in. Everytime we get a match, increase our counter by 1.
I believe you understand the concept and what you need to do but it was perhaps just the wording that caught you off guard. Post back and let me know if you need help or if you got it working!!
