1,350 PointsLogic seems write , What's the mistake ?
I did everything in the question step by step, but the code is not passing the test case , have rechecked the code many times but it seems right, What's the mistake ?
public class ScrabblePlayer {
private String mHand;
private int mCount=0;
public ScrabblePlayer() {
mHand = "";
}
public String getHand() {
return mHand;
}
public void addTile(char tile) {
// Adds the tile to the hand of the player
mHand += tile;
getTileCount(tile);
}
public boolean hasTile(char tile) {
return mHand.indexOf(tile) > -1;
}
public int getTileCount(char tile){
for(char letter : mHand.toCharArray()){
if(tile == letter){
mCount++;
}
}
return mCount;
}
}

23,733 PointsAt the top of the class declare mCount, but don't initialize it yet. Set mCount to zero inside the method since it needs t be zero each time the method is called:
public class ScrabblePlayer {
private String mHand;
private int mCount;
public ScrabblePlayer() {
mHand = "";
}
public String getHand() {
return mHand;
}
public void addTile(char tile) {
// Adds the tile to the hand of the player
mHand += tile;
getTileCount(tile);
}
public boolean hasTile(char tile) {
return mHand.indexOf(tile) > -1;
}
public int getTileCount(char tile){
mCount=0
for(char letter : mHand.toCharArray()){
if(tile == letter){
mCount++;
}
}
return mCount;
}
}
Actually, I see no reason why you need a member variable here, so I would just use a local variable:
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;
getTileCount(tile);
}
public boolean hasTile(char tile) {
return mHand.indexOf(tile) > -1;
}
public int getTileCount(char tile){
int count = 0;
for(char letter : mHand.toCharArray()){
if(tile == letter){
count++;
}
}
return count;
}
}

Treehouse TeacherYep the member variable is messing you up...I run a couple of test cases through and it is incrementing each time. A local variable will work!
