15,353 PointsHey Alexander,
The completed code looks like this
public int getTileCount(char tile) {
int count = 0;
for (char tiles : mHand.toCharArray()) {
if (tiles==tile) {
count++;
}
}
return count;
}
So first we create the method that accepts a char. we then initialize a counter variable that starts at 0. Now we're going to convert mHands to an array of chars so we can loop through each char. Each time we loop through a mHand char, we store it as tiles. So now if mHands consisted of "asdfu" for example, it would now look like this ["a","s","d","f","u"]. Its a array of chars!. and now we loop through each one. so in the first loop, "tiles" would hold the letter "a" and then so on. We check if the tile we're looping on is equal to the one we passed in. If they match, then increase the counter by 1. Once we loop thorugh all the chars and check if it equals the one we pass in, we return the count.
Does that make sense?
