Android Development Techdegree Student 968 PointsCan't return an int.
I am currently trying to pass the ScrabblePlayer challenge where I have to create a getTileCount method, but when I try to return tileCount, I get this
./ScrabblePlayer.java:18: error: incompatible types: int cannot be converted to String return tileCount; ^
public class ScrabblePlayer {
private String mHand;
public ScrabblePlayer() {
mHand = "";
}
public String getHand() {
return mHand;
}
public int tileCount = 0;
public String getTileCount(char validTile) {
for (char tile : mHand.toCharArray()) {
if (tile == validTile) {
tileCount++;
}
return tileCount;
}
}
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;
}
}

private String mHand;
public ScrabblePlayer() {
mHand = "";
}
public String getHand() {
return mHand;
}
public int getTileCount(char tile) {// "tile" just for naming purposes. Use "int" since we are returning that
int tileCount = 0;// declare your int variable and set it equal to 0
for (char tileInHand : mHand.toCharArray()) {// create new char, the one "we" have
if (tileInHand == tile) {// if the tile we have is the same as the original
tileCount++;// increment the tile count, which means we have more than one
}
}
return tileCount;// return the amount of that tile that we have
}
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;
}
}
Pixel HD, I do hope that this helps you! If I made any errors feel free to let me know! You have to define the return type of the method getTileCount() as an int, since that is what we are going to return. Happy coding!
