2,175 PointsStage 3 : Creating the MVP, Challenge Task 1 of 1.
This is the error I am receiving: Bummer! The hand was "sreclhak" and 'e' was checked. Expected 1 but got 8.
public int getTileCount(char letter) {
int tileCount = 0;
for(char tile : mHand.toCharArray()) {
if(mHand.indexOf(tile) >= 0) {
tileCount++;
}
}
return tileCount;
}

Is this the challenge to which you are referring? If so, it is a Java course, not an Android course. Anyway, post back and someone can certainly answer your question. Also, if you post the code you have tried it will help to see where the issue is.
Thanks,
Ken

The way you have it set up right now, you're essentially getting each tile in the hand, and then checking to see if the tile is in the hand (and incrementing tileCount if it is). This is why the test example from the workspace received 8 instead of 1.
What you want to do instead is look at each tile in the hand (your for each loop does this) and check to see if the letter being passed into the method matches the tile we are looking at (this is your if condition). If it is, then increment tileCount. This should accurately represent the number of times the letter shows up in the tiles in the hand.
Hope this helps! Feel free to let me know if you have further questions.

1,443 PointsWelcome to a little Twitter-like application. Here I'm modeling a Tweet. It has text which is the body of the tweet. All Tweets have a maximum character limit of 140 characters.
Please add a new constant to store the maximum number of characters allowed which is 140. Use the proper access level modifiers to make it unchangeable and accessible right off of the class. Follow the proper naming convention.
