So back to that ScrabblePlayer. I found that it's not enough to know if they just have a tile of a specific characte

I seem to be having a real hard time absorbing the information in these videos , I watch them ( multiple times) I write the code down but when it comes to the questions I completely fall apart its like things just don't make sense should I just give up trying? even when I go to try find the answers on the forums sometimes they don't make sense.

Anyway this task just really stumped me I feel like the videos don't go fully into depth and everything is just rushed

ScrabblePlayer.java 
public class ScrabblePlayer {
  private String mHand;

  public ScrabblePlayer() {
    mHand = "";
  }

  public String getHand() {
   return mHand;
  }

  public int getTileCount(char t){
    int count = 0; 
    for (char tile : mHand.toCharArray()){
      if (tile == t) {
         count++;
      }
    }

    return count;
  }
}

  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;
  }
}

Well... I don't know about anything else, but definitely don't give up! Listen, persistence generally pays off... eventually. Now, a while ago I posted a rather detailed explanation about this challenge. Take a look at my explanation and see if it doesn't clarify it a bit! I sincerely hope this helps, and by all means... hang in there!

Two questions here,

First "[..]should I just give up trying?"

Not at all! :D The fact that you're "struggling" through it and pushing on is great. [1]

Second, it looks like you have an extra "}" on line 22. I checked your code and ran it through without that bracket, and it passed! :)

[1] Edit: To add, some people learn well when struggling through a problem. I'm one of those people. I could spend days on something struggling through it, going through every possible solution I can think of, then, it hits me, and I got it! And b/c of that whole ordeal I can recall it well.
