strings and stars challenge 2

Question

Hello there, I'm getting stuck with the second challenge. I thought it should be something with if and else. But don't know how, cause you have to compare a string with a char. I found an answer somewhere in the community, but couldn't work that one out and it didn't if and else like it was used in the video.

Can someone please help me out? Thank you!

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) {
     if (hasTile) {
       tile == mHand;
       return true;
     } else {
       return false;
    }
}

Hi Jari!

Here's a possible solution:

public boolean hasTile(char tile) {
     if (mHand.contains(tile + "")) {  // check if mHand contains the char tile with the contains() method
       return true; // if yes return true and exit the method
     }
       return false; // if not, simply return false
}

I encourage you to look at this method more deeply and if you have questions, go and ask them!

Hi Jari,

Gabors advice is cool. You can use the indexOf method too. The code snippet is more clear then.

Like this:

public boolean hasTile(char tile) {
    return mHand.indexOf(tile) > -1;
// the indexOf method returns an integer
// if tile is not in mHand the integer will be -1 (returned boolean value is false)
// if tile is in mHand the integer will be greater then -1 (returned boolean value is true)
}
