public int getTileCount() { int count = 0; for (char tile: mHand.indexOf(tile) >= 0) { count += 1; } return count; }
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 int getTileCount() {
int count = 0;
for (char tile: mHand.indexOf(tile) >= 0) {
count += 1;
}
return count;
}
}

public int getTileCount(char tile) { // accepts a char
int count = 0;
for (char tile1: mHand.toCharArray()) { // for loop
if(tile1 == tile){
count += 1;
}
}
return count;
}

45,831 PointsThanks for the help. I did not realize that the first declaration inside the 'for each' parenthesis is nothing more than a labeling of the items following the colon. That enables further working inside the curly braces, such as the test for equality that you are showing me in your code. I see now. Thanks.
There is no counter in this method. It is really just a flag of a Boolean type. It can be either zero or one, but will not add up because only one char can be passed in, and count is initialized to zero every time.
