6,167 PointsIm not able to succesfully complete the code challenge, and I do not get where Im going wrong. (For each loop)
Instructions: So back to that ScrabblePlayer. I found that it's not enough to know if they just have a tile of a specific character. We need to know how many they actually have. Can you please add a method called getTileCount that uses the for each loop you just learned to loop through the characters and increment a counter if it matches? Return the count, please, thanks!
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 String getTileCount(){
String count="";
for (char tile : mHand.toCharArray()) {
char display= '-';
if(mHand.indexOf(tile) >= 0){
display = tile;
}
count += display;
}
return count;
}
}*/

28,694 Pointscount should be an int.
you need to receive the character to look for as a parameter.
use == to test primitive chars. Indexof is incorrect. You're essentially testing each character in the string to confirm it's in the string.
