Strings and Char Objective #2

Can you please fill out the addTile method so that it takes the char that is passed and adds it to the mHand member field? Thanks!

ScrabblePlayer.java 
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) ;
       return false;
    }
}

Hi there,

This is a funny challenge:

The method hasTile takes a char that you compare with every char inside of the String mHand. The problem is that String is not of a char type. String typeis a concatenation of characters. So you need to build a char array from the mHand String and compare every char with your parameter "tile".

To compare every single unit of something you can use a for loop. Inside this loop you are assigning a character from mHand to a new char variable. And compare this new character with tile.

Look at this code:

// TASK 1
    public void addTile(char tile) {
        // Adds the tile to the hand of the player
      mHand += tile;
    }

// TASK 2
    public boolean hasTile(char tile) {
// the method take a char that you will compare with every single char from the String mHand
      for (char charFromHand: mHand.toCharArray()) {
// here you are making a character array
       if (charFromHand == tile) { 
// if a char from mHand is equals to tile
// return true
          return true; 
       }
      }
       return false;
    }
