Hello,
I created a getTileCount() method that works when I tested it out in my Hangman Workspace. But the task is saying : "Did you forget to create the method getTileCount that accepts a char?" Can someone please clarify what the task is saying by "accepts a char"?
Does it mean that the method needs to be in 'getTileCount(char letter)' format (which can be unnecessary)?
Thank you!
Here is my code for the task:
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(){
int counter = 0;
for (char letter: mHand.toCharArray()) {
counter += 1;
}
return counter;
}
}

Yes, you need to pass a character because the instructions say that you should only increment the count if the character passed into the method matches any of the characters in mHand as you are iterating through them. I hope that helps.

Thank you for the clarification. I thought the question was just asking for the number of tiles in a hand.

public int getTileCount(char letter) {
int count = 0;
for (char letter: mHand.toCharArray()) {
count += 1;
}
return count;
}
What is the alternative to traversing the characters in mHand instead of using for (char letter: mHand.toCharArray())? I appreciate any help.

21,223 PointsThe for each loop is traversing each character of mHand. On the first iteration you get the first character of the array of characters within mHand and continue until the last character. The idea here is to test whether or not the character you pass into the method ever matches a character within mHand on any one iteration. Therefore, you should name the parameter that you are passing into the method with something different than letter (i.e. theLetter). Then use an if statement to test if letter == theLetter. Increment the count if it does. The reason you can use == to test instead of .equals stems from the fact that characters are essentially numbers via ASCII. I hope that helps.

1,174 PointsChristopher Augg I want to thank you for what you said here. I had done the challenge once before but I forgot how to solve it. Rather than look for the answer else where I was looking for a post that would help me think my way to the answer. Now I have it solved and learned something new about how to think like a programmer.
public int getTileCount(char tile) {
int counter = 0;
char theTile = tile;
for (char tiles : mHand.toCharArray()) {
if (tiles == theTile) {
counter++;
}
}
return counter;
}

1,174 PointsI was just thinking about this solution that I came up with and I realized that I could have done without the
char theTile = tile;
I could have or should have just just passed the "char tile" into the "if" statement. But hey both ways work. I should written down the code on paper so that maybe I would have seen that I could have sharpen and cleaned up my code.
